KembaraXtra-Islamic Finance: The Technical Definition of a Contract
Introduction
In modern legal systems, a contract is generally defined as an agreement between two or more parties that creates an obligation to do, or not to do, a specific act. It is a framework that binds the rights and responsibilities of those who enter into it. Surprisingly, traditional Islamic commercial law did not initially produce a systematic or technical definition of a contract (‘Aqd). Instead, the nature and principles of contracts were derived mainly through discussions of sales (al-bay‘), since sales were the most common and practical form of transaction.
Islamic jurists examined issues such as offer (ijab), acceptance (qabul), and their relationship to legal rights and liabilities within the context of sales rather than in a dedicated, overarching chapter on contracts. This does not mean that contracts were foreign to Islamic civilization—on the contrary, the Qur’an itself explicitly mentions contracts and their sanctity. Early Muslim jurists embedded the rules of contracts across various transactional areas such as sales, leases, and partnerships rather than codifying them under one heading.
It was only later, particularly with the codification of the Ottoman Civil Code, Majallah al-Ahkam al-‘Adliyyah (commonly known as the Mejelle), that a precise technical definition of contract emerged. The Mejelle defined a contract as “the connection of an offer with an acceptance in a lawful manner which marks its effect on the subject of that connection.” This definition resembles that of modern systems but is distinctive in requiring that the contract’s manner and effect comply with Shari’ah principles.
Therefore, while the systematic study of contracts in Islamic law is relatively recent, the principles have always been present in Islamic jurisprudence. Today, scholars and practitioners extract these principles from classical discussions and apply them in shaping the general theory of Islamic contracts for contemporary financial and commercial practice.
Case Studies with Solutions
Case 1: Partnership to Produce Alcoholic
Scenario: Two business partners form a contract to manufacture and export alcohol to non-Muslim countries.
Solution: Invalid. Even if mutual consent exists, the object of the contract is unlawful (haram). The Mejelle’s requirement of a contract being concluded “in a lawful manner” makes this void.
Sale Without Clear Offer and Acceptance
Scenario: A shopkeeper places goods on display. A customer takes the goods and leaves money without verbally communicating acceptance, and the seller later disputes the price.
Solution: Invalid or disputable. Islamic law requires clear ijab (offer) and qabul (acceptance). Silence or assumption does not establish consent. A valid contract must explicitly show mutual agreement on price and object.
Case 3: Lease Contract With Unlawful Condition
Scenario: A landlord rents out an apartment but includes a condition that the tenant must not perform daily prayers inside the premises.
Solution: Invalid. While the lease itself is permissible, the unlawful condition violates Shari’ah principles. Contracts must be lawful not only in form but also in conditions attached.
Case 4: Forward Sale of Crops (
Salam
)
Scenario: A farmer sells 100 kg of dates to be delivered in six months. The buyer pays upfront, but the weight and quality are not specified.
Solution: Voidable. A valid salam contract requires clear specification of the commodity’s type, quantity, and delivery date to prevent disputes. Without this, the contract suffers from gharar (excessive uncertainty).
Case 5: Deposit Taking (
Wadi‘ah
) With Misuse
Scenario: Mariam deposits gold jewellery with a custodian under a safekeeping contract. The custodian later uses the jewellery for personal gain, intending to return it later.
Solution: Invalid conduct. The custodian has breached trust, and the contract is violated. Under Islamic law, wadi‘ah requires safekeeping only. The custodian is liable to compensate Mariam for any damage or loss.
l
Conclusion
The technical definition of contracts in Islamic law developed gradually, with the Mejelle providing the first formal articulation. Unlike modern systems, Islamic law embeds a moral requirement—that contracts must be lawful under Shari’ah. The essence of contracts lies in the valid connection of offer and acceptance, with clear consent, fairness, and lawfulness.
Through real-world examples—ranging from unlawful objects to ambiguous terms and breaches of trust—we see how the technical framework ensures that contracts serve their higher purpose: safeguarding rights, preventing harm, and aligning commercial dealings with Islamic ethical values.

KembaraXtra-Islamic Finance: Bilateral and Unilateral Contracts
Introduction
In Islamic commercial law, contracts are broadly classified into two major categories: bilateral contracts (al-‘uqud al-i’tiqadiyyah) and unilateral contracts (al-‘uqud al-tabarru’iyyah). This classification is fundamental because each type carries different legal features, obligations, and implications.
A bilateral contract arises when two parties, each with full legal capacity, agree to exchange something of value. It is primarily commercial in nature, and therefore, conditions such as clarity, mutual consent, and freedom from uncertainty (gharar) are strictly required. The purpose is to ensure fairness and to avoid disputes.
A unilateral contract, on the other hand, is generally gratuity-based. It is formed when one party makes an offer (such as a gift, donation, or will) without expecting any return or compensation. In such cases, acceptance or consideration by the recipient is not required for validity. Furthermore, minor uncertainty (gharar) is tolerated in unilateral contracts, because the purpose is not commercial gain but generosity and goodwill.
The Qur’an emphasizes the importance of fulfilling obligations:
“O you who believe, fulfill [all] contracts.” (Surah Al-Ma’idah 5:1)
The Prophet ﷺ said:
“The Muslims are bound by their conditions, except a condition that makes the lawful unlawful, or the unlawful lawful.” (Sunan al-Tirmidhi)
These references highlight that whether bilateral or unilateral, contracts must be respected, but their rules differ according to purpose.

Solution: Valid unilateral act. Qur’an 2:280 praises those who remit debts.
Case 7: Salam Sale (Bilateral)
Scenario: A farmer sells 500kg of dates for delivery in 6 months, paid fully in advance.
Solution: Valid Salam contract. All specifications must be clear. Hadith in Sahih Muslim permits advance payment.
Case 8: Charitable Donation (Unilateral)
Scenario: Mariam donates RM2,000 to a mosque for repairs.
Solution: Valid unilateral donation (sadaqah). No consideration required. Qur’an 2:261 praises charity.
Case 9: Agency Contract (Bilateral)
Scenario: A hires an agent to buy goods on his behalf, paying a commission fee.
Solution: Valid Wakalah contract. Commercial nature requires clear terms.
Case 10: Inheritance Waiver (Unilateral)
Scenario: A daughter waives her right to inherit a family property out of goodwill.
Solution: Valid unilateral waiver (tanazul). She is not obliged to accept her share if willingly waived.
Conclusion
Bilateral and unilateral contracts represent two core foundations of Islamic contract law. Bilateral contracts emphasize commercial exchange, requiring strict clarity, mutual consent, and prohibition of gharar. Unilateral contracts reflect goodwill and generosity, where consideration and acceptance are not required, and some uncertainty is tolerated.
By mastering the distinctions and applications of these contracts, Islamic finance practitioners can structure Shari’ah-compliant products that both serve commercial purposes and uphold ethical, charitable values rooted in the Qur’an and Sunnah.

KembaraXtra-Islamic Finance: Differences Between Bilateral and Unilateral Contracts
Bilateral Contracts
- Require two or more parties.
- Consideration is required (exchange of value).
- Acceptance by the offeree is necessary.
- Purpose is commercial or transactional (sale, lease, partnership, etc.).
- Must be free from gharar (uncertainty) – clear terms on price, object, payment, and delivery.
Unilateral Contracts
- Require only one party (offeror).
- No consideration required from the recipient.
- Acceptance not required for validity.
- Purpose is gratuity or goodwill (gift, donation, will, waiver, etc.).
- Gharar (uncertainty) is tolerated since no commercial risk or exchange is involved.
Qur’an and Hadith Reinforcement
- “Do not consume one another’s wealth unjustly, but only [in lawful] business by mutual consent.” (Surah An-Nisa 4:29) → Governs bilateral contracts.
- “Whoever removes a worldly grief from a believer, Allah will remove from him one of the griefs of the Hereafter.” (Sahih Muslim) → Encourages gratuitous (unilateral) acts like gifts and donations.
- “Give the worker his wages before his sweat dries.” (Ibn Majah) → Reinforces bilateral fairness in commercial contracts.

KembaraXtra-Islamic Finance: The Need of Ijtihad in Modern Times
Introduction
Islamic law (Shari’ah) is rooted in divine revelation through the Qur’an and Sunnah. However, with the passing of Prophet Muhammad (peace be upon him), revelation ceased, leaving subsequent generations to rely on scholarly reasoning (Ijtihad) for guidance in new and complex situations. As human society evolves, novel cases arise—particularly in the financial sector—that were never encountered during the early centuries of Islam. Modern developments such as short selling, derivatives trading, swap transactions, and futures markets highlight the urgency of Ijtihad.
Even classical contracts like Musharakah and Ijarah present challenges when applied in modern frameworks, for example, issues of redeeming Musharakah capital or structuring floating rental rates based on benchmarks such as LIBOR. These are not theoretical problems but real challenges faced by Islamic financial institutions across the globe.
If Ijtihad is neglected, two outcomes become likely: (1) Islam may appear incapable of addressing modern realities, and (2) ad hoc rulings by unqualified individuals could lead to inconsistent or invalid solutions. Properly conducted Ijtihad, however, provides systematic, transparent, and probable rulings that balance authenticity with practicality. Importantly, such rulings are not absolute like Qur’anic injunctions but represent the best-probable outcomes based on structured reasoning.
To meet contemporary needs, modern Islamic societies emphasize:
- Scholarship of the Mujtahid – Jurists must be well-qualified, knowledgeable, and respected by the community.
- Collective Ijtihad – Greater reliance is placed on councils and institutions such as AAOIFI, OIC Fiqh Academy, and Shari’ah boards of Islamic banks.
- Publication of Resolutions – Making rulings public ensures transparency, builds trust, and allows widespread acceptance across jurisdictions.
This framework ensures that Ijtihad remains the intellectual engine driving Islamic finance, enabling it to remain Shari’ah-compliant, relevant, and competitive in global markets.
Case Scenarios with Solutions
Case 1: Short Selling in Equity Markets
Scenario: An investor wants to engage in short selling of stocks, profiting from price declines.
Solution: Classical Shari’ah prohibits selling what one does not own. Instead, Islamic finance introduces alternatives such as Salam contracts (advance sale) or Arbun (earnest money sale), offering permissible ways to hedge risks without violating ownership principles.
Case 2: Islamic Alternatives to Derivatives (Options & Swaps)
Scenario: A company seeks to hedge against currency fluctuations using conventional options and swaps.
Solution: Jurists permit structured Islamic contracts like Wa’ad (unilateral promise) and Murabahah (cost-plus financing) to serve as hedging tools, avoiding excessive uncertainty (gharar) and speculation. These alternatives align with the principles of risk-sharing and real asset backing.
Case 3: Floating Rental Rates in Ijarah
Scenario: A bank structures an Ijarah (leasing) contract with rental payments tied to LIBOR, but stakeholders question Shari’ah compliance.
Solution: While LIBOR itself is an interest-based benchmark, its use as a pricing reference—not as a contract element of interest—is tolerated under Ijtihad for practical reasons. Scholars encourage developing independent Islamic benchmarks, but until then, LIBOR linkage is accepted as a transitional necessity.
Case 4: Redemption of Musharakah Capital
Scenario: A business partner in a Musharakah contract requests early redemption of his capital contribution.
Solution: Ijtihad permits redemption if all parties agree and the capital is valued fairly at market rates. This ensures justice while providing flexibility. Profit/loss distribution is adjusted to reflect the actual tenure of participation.
Case 5: Cryptocurrency as a Medium of Exchange
Scenario: An Islamic bank is approached to accept cryptocurrency deposits. Concerns arise about volatility and legitimacy.
Solution: If the cryptocurrency is recognized as a tradable asset with transparent valuation, and is not linked to prohibited activities (gambling, interest, fraud), it can be treated as a form of wealth. However, jurists recommend cautious regulation and collective Ijtihad for standardization.
Case 6: Green Sukuk for Sustainable Development
Scenario: A government wants to issue Sukuk to finance renewable energy projects and carbon trading schemes.
Solution: Scholars permit Green Sukuk since the proceeds fund Shari’ah-compliant projects that promote public welfare (maslahah). Ijtihad validates this innovation, provided structures avoid prohibited elements like interest-based guarantees.
Conclusion
Ijtihad is indispensable in modern times, particularly in Islamic finance, where new products and challenges emerge daily. From addressing short selling and floating rental benchmarks to pioneering cryptocurrency and Green Sukuk, jurists use Ijtihad to bridge classical principles with contemporary realities. Through qualified scholarship, collective reasoning, and transparent publication of rulings, Islamic finance remains both faithful to Shari’ah and responsive to global market demands.

KembaraXtra-Islamic Finance: The Meaning of Contract (‘Aqd) in Islamic Commercial Law
Introduction
Contracts (‘Aqd) lie at the heart of Islamic commercial law (Fiqh al-Mu‘āmalāt), serving as a foundation for regulating human interactions in trade, business, family matters, and even governance. A contract is not merely a technical arrangement—it represents an ethical and legal bond that facilitates cooperation, fairness, and justice in society. In Islamic jurisprudence, the formation and effect of a contract are equally important. A contract may be classified as valid (sahih), invalid (batil), or voidable (fasid) depending on whether it complies with the essential conditions of Shari’ah.
The ultimate purpose of contracts is to enable individuals and communities to meet their legitimate needs in a way that reflects the divine principles of justice and balance. Contracts can be political, social, commercial, or family-based. For example, in commerce they regulate trade and partnerships, while in family life they govern marriage and divorce.
The Majallah al-Ahkam al-‘Adliyyah (Islamic Civil Code of the Ottoman Empire, 1876), widely known as the Mejelle, underscores this principle by affirming that human beings are social by nature. A person cannot live in isolation but requires cooperation with others to build and sustain an organized society. Yet, human nature also inclines toward competition, which can lead to disputes. Hence, laws are necessary to maintain justice, protect rights, and ensure that contracts are fulfilled in ways that uphold Shari’ah objectives.
Thus, contracts in Islamic law are more than transactional tools—they are moral and social instruments that promote order, fairness, and mutual benefit.
Case Scenarios with Solutions
Case 1: Sale Without Clear Ownership
Scenario: Ahmad sells a car to Bilal, but at the time of the agreement, Ahmad does not actually own the car. He intends to buy it later from a dealer and then transfer it.
Solution: The contract is invalid (batil) because ownership is a prerequisite for selling. A person cannot sell what he does not own. To comply with Shari’ah, Ahmad must first purchase the car and take ownership before entering into the sale contract.
Case 2: Marriage Contract With Missing Consent
Scenario: A father arranges a marriage contract for his adult daughter without her knowledge or consent.
Solution: In Islamic law, the consent of both parties is essential for a valid marriage contract. Without the daughter’s explicit approval, the contract is voidable (fasid) and cannot be enforced. Consent must be secured to ensure the contract is legitimate.
Case 3: Mudarabah Partnership With Ambiguous Profit-Sharing
Scenario: Fatimah invests capital in a Mudarabah partnership with Yusuf, who provides expertise and management. They agree that Yusuf will receive a “fair share” of profit but do not specify a ratio.
Solution: The contract is defective because the profit-sharing ratio must be explicitly agreed upon (e.g., 60:40). Without clarity, disputes may arise. The contract must be revised with a fixed, mutually agreed profit ratio for it to be valid.
Case 4: Lease Agreement With Unfair Terms
Scenario: An Islamic bank leases machinery to a client under an Ijarah contract. The agreement states that the lessee must continue paying rent even if the machinery breaks down and cannot be used.
Solution: The contract is voidable because Islamic law requires that the lessor (owner) bears the risk of ownership. If the machinery becomes unusable without the lessee’s fault, the rental obligation ceases. The bank must repair or replace the machinery for the contract to remain valid.
Case 5: Sale of Prohibited Goods
Scenario: A merchant enters into a contract to sell alcohol to a customer in a Muslim-majority country.
Solution: The contract is invalid (batil) because its subject matter is prohibited (haram) in Shari’ah. A valid contract must deal only with lawful (halal) goods or services. The merchant must restrict sales to permissible items to comply with Islamic commercial law.
L
Conclusion
The concept of contract (‘Aqd) in Islamic commercial law is deeply rooted in ethics, social responsibility, and legal structure. From regulating trade to governing family life, contracts serve as a means of ensuring justice, fairness, and cooperation in society. The Mejelle highlighted that human beings, as social creatures, require laws to balance cooperation with competition. Islamic law therefore provides structured rules that classify contracts as valid, invalid, or voidable, ensuring that they serve legitimate needs while aligning with Shari’ah objectives.
Through practical applications, such as in sales, leasing, partnerships, and family arrangements, Islamic jurisprudence demonstrates that contracts are not only legal frameworks but also vehicles for promoting justice and preserving social harmony.

KembaraXtra-Islamic Finance: The Nature of Contract
Introduction
In Islamic law, the concept of contract—referred to in Arabic as ‘Aqd—literally means “to tie.” It symbolizes the binding connection that joins two parties: the offeror and the offeree. Contracts are not only tools for conducting transactions but also instruments that formalize human cooperation and establish rights, duties, and liabilities between individuals and institutions.
The role of contracts extends beyond simple commercial exchanges. They are deeply embedded in the organization of society, encompassing political, social, economic, and religious dimensions. For instance, a contract may govern the relationship between a ruler and the ruled, a husband and wife, or business partners in trade. In every sphere, contracts help to secure order, fairness, and mutual benefit.
Within Islamic commercial law (Fiqh al-Mu‘āmalāt), contracts serve as the legal backbone for financial dealings such as sales, leases, partnerships, and agency. They are both jurisprudentially rich and practically vital, representing one of the most intellectually stimulating areas of Islamic law. Without contracts, structured human interaction—whether in primitive communities or modern economies—would be impossible. They express the intentions of the parties and give them a framework to realize those intentions lawfully under Shari’ah.
Case Scenarios with Solutions
Case 1: Contract Without Clear Terms
Scenario: Two business partners agree verbally to share profits from a new store but fail to specify the ratio.
Solution: The contract is defective because ambiguity in profit-sharing (gharar) can lead to disputes. To be valid, the agreement must state an explicit ratio (e.g., 60:40). Written documentation further ensures clarity and enforceability.
Case 2: Marriage Contract Without Witnesses
Scenario: A man and woman agree to marry and exchange vows privately without any witnesses.
Solution: Islamic law requires at least two witnesses for a valid marriage contract. Without witnesses, the marriage is voidable (fasid). The couple must renew the contract with witnesses present for legitimacy.
Case 3: Lease Contract With Improper Risk Transfre
Scenario: A bank leases office space to a client under an Ijarah contract but stipulates that the tenant must pay for structural repairs to the building.
Solution: This condition invalidates the lease because the lessor must bear ownership-related risks and responsibilities. Structural repairs fall under the landlord’s obligations. Only maintenance costs related to usage can be charged to the tenant.
Case 4: Sale of Unlawful Goods
Scenario: A trader contracts to sell pork and alcohol in a Muslim-majority jurisdiction.
Solution: The contract is invalid (batil) because its subject matter is prohibited (haram) under Shari’ah. Only lawful goods and services can form the subject of valid contracts in Islamic law.
Case 5: Deferred Payment Sale Without Clarity
Scenario: A shopkeeper sells a laptop on credit but fails to mention the due date for payment.
Solution: The sale is defective because the payment schedule is unclear. Shari’ah requires certainty in terms and conditions to avoid disputes. The seller must specify when and how payment will be made for the contract to be valid.
Conclusion
Contracts in Islamic law are not merely legal mechanisms but moral bonds that regulate relationships across social, political, family, and financial spheres. By “tying” parties together, contracts provide structure, fairness, and accountability in human interactions. From sales to leases and marriages, the validity of contracts depends on compliance with Shari’ah requirements such as clarity, lawful subject matter, consent, and proper allocation of risk.
The concept of ‘Aqd thus demonstrates Islam’s holistic vision of law—where contracts serve not only economic needs but also uphold justice and preserve social harmony in every aspect of life.
Introduction
In Islamic law, the concept of contract—referred to in Arabic as ‘Aqd—literally means “to tie.” It symbolizes the binding connection that joins two parties: the offeror and the offeree. Contracts are not only tools for conducting transactions but also instruments that formalize human cooperation and establish rights, duties, and liabilities between individuals and institutions.
The role of contracts extends beyond simple commercial exchanges. They are deeply embedded in the organization of society, encompassing political, social, economic, and religious dimensions. For instance, a contract may govern the relationship between a ruler and the ruled, a husband and wife, or business partners in trade. In every sphere, contracts help to secure order, fairness, and mutual benefit.
Within Islamic commercial law (Fiqh al-Mu‘āmalāt), contracts serve as the legal backbone for financial dealings such as sales, leases, partnerships, and agency. They are both jurisprudentially rich and practically vital, representing one of the most intellectually stimulating areas of Islamic law. Without contracts, structured human interaction—whether in primitive communities or modern economies—would be impossible. They express the intentions of the parties and give them a framework to realize those intentions lawfully under Shari’ah.
Case Scenarios with Solutions
Case 1: Contract Without Clear Terms
Scenario: Two business partners agree verbally to share profits from a new store but fail to specify the ratio.
Solution: The contract is defective because ambiguity in profit-sharing (gharar) can lead to disputes. To be valid, the agreement must state an explicit ratio (e.g., 60:40). Written documentation further ensures clarity and enforceability.
Case 2: Marriage Contract Without Witnesses
Scenario: A man and woman agree to marry and exchange vows privately without any witnesses.
Solution: Islamic law requires at least two witnesses for a valid marriage contract. Without witnesses, the marriage is voidable (fasid). The couple must renew the contract with witnesses present for legitimacy.
Case 3: Lease Contract With Improper Risk Transfre
Scenario: A bank leases office space to a client under an Ijarah contract but stipulates that the tenant must pay for structural repairs to the building.
Solution: This condition invalidates the lease because the lessor must bear ownership-related risks and responsibilities. Structural repairs fall under the landlord’s obligations. Only maintenance costs related to usage can be charged to the tenant.
Case 4: Sale of Unlawful Goods
Scenario: A trader contracts to sell pork and alcohol in a Muslim-majority jurisdiction.
Solution: The contract is invalid (batil) because its subject matter is prohibited (haram) under Shari’ah. Only lawful goods and services can form the subject of valid contracts in Islamic law.
Case 5: Deferred Payment Sale Without Clarity
Scenario: A shopkeeper sells a laptop on credit but fails to mention the due date for payment.
Solution: The sale is defective because the payment schedule is unclear. Shari’ah requires certainty in terms and conditions to avoid disputes. The seller must specify when and how payment will be made for the contract to be valid.
Conclusion
Contracts in Islamic law are not merely legal mechanisms but moral bonds that regulate relationships across social, political, family, and financial spheres. By “tying” parties together, contracts provide structure, fairness, and accountability in human interactions. From sales to leases and marriages, the validity of contracts depends on compliance with Shari’ah requirements such as clarity, lawful subject matter, consent, and proper allocation of risk.
The concept of ‘Aqd thus demonstrates Islam’s holistic vision of law—where contracts serve not only economic needs but also uphold justice and preserve social harmony in every aspect of life.

KembaraXtra-Islamic Finance: Contracts and the Qur’an
Introduction
In Islamic jurisprudence, the concept of contract (‘Aqd) is both sacred and practical. The Qur’an and Sunnah are the primary sources of law, and they establish the foundational principles of contractual dealings. Unlike other legal systems that evolved mainly through secular reasoning, Islamic law begins from divine revelation. The Qur’an highlights contracts as binding obligations that reflect not only mutual agreements but also moral and spiritual accountability.
The Qur’an uses the term ‘Aqd—literally meaning “to tie” or “to knot”—to describe the bond that contracts create between the offeror and the offeree. It is not merely a legal tool but a moral commitment to fairness and honesty. Surah al-Mā’idah (5:1) instructs: “O you who believe! Fulfil your contracts.” This verse enshrines the principle of honoring promises and respecting obligations, which underpins all forms of transactions.
Surah al-Nisā’ (4:29) further clarifies the ethical foundation: “Do not consume one another’s wealth unjustly, but only [in lawful] business by mutual consent.” This emphasizes that valid contracts require genuine consent, free from exploitation, fraud, or coercion. In addition, the Qur’an mentions around 40 verses related to various types of contracts, including sale, hire (ijarah), forward sale (salam), debt-based transactions, pledges, guarantees, and fiduciary agreements. These references show that contracts, in diverse forms, were common during the time of revelation and remain integral today.
Thus, in Islamic commercial law, contracts are not just legal structures but vehicles to safeguard trust, justice, and social harmony. They serve as a bridge between divine injunctions and human interaction in commerce, politics, and family life.
Case Scenarios with Solutions
Case 1: Sale Without Mutual Consent
Scenario: A shopkeeper pressures a poor villager into buying goods he doesn’t need.
Solution: The contract is invalid because Qur’an 4:29 requires mutual goodwill and consent. Coercion invalidates the agreement.
Case 2: Delayed Fulfilment of Debt
Scenario: Khalid borrows money under a debt contract but refuses to repay despite ability.
Solution: The Qur’an obliges debtors to honour commitments. Deliberate delay is unjust; courts may enforce repayment and impose consequences for negligence.
Case 3: Forward Sale (
Salam
) in Agriculture
Scenario: A farmer sells wheat in advance for delivery in six months at a fixed price.
Solution: This is permissible under Qur’anic guidance as long as the quantity, quality, and delivery date are specified. Salam contracts support farmers with upfront financing.
Case 4: Hire Contract (
Ijarah
) with Unfair Burden
Scenario: A landlord leases a house but forces the tenant to pay property taxes.
Solution: Invalid. In Shari’ah, ownership risks (like taxes or major repairs) must remain with the lessor. Only usage-related expenses can be passed to the tenant.
Case 5: Guarantee Contract (
Kafalah)
Scenario: A guarantor agrees to cover Ali’s loan if he defaults. Ali defaults, but the guarantor refuses payment.
Solution: The Qur’anic principle of fulfilling obligations makes the guarantor liable. The guarantee is binding and enforceable.
Case 6: Sale of Prohibited Goods
Scenario: A merchant enters a contract to sell alcohol to a non-Muslim buyer.
Solution: Invalid, as Qur’an prohibits unlawful (haram) items from being traded. The contract is void regardless of mutual consent.
Case 7: Debt Contract Without Documentation
Scenario: Ahmad lends his friend 1,000 dinars but fails to document the transaction. Later, the friend denies it.
Solution: Qur’an 2:282 advises documenting debts in writing and involving witnesses. While the loan remains valid, lack of proof complicates enforcement.
Case 8: Breach of Promise in Partnership (
Musharakah)
Scenario: Two partners agree to contribute equally to a business, but one fails to deliver his share.
Solution: The defaulting partner is in breach of Qur’anic injunctions to fulfil commitments. The other partner may seek restitution or dissolve the contract.
Case 9: Hire of Labour Without Clear Wages
Scenario: A contractor hires workers but doesn’t agree on wages before work begins.
Solution: Invalid contract due to ambiguity (gharar). Wages must be specified beforehand to ensure fairness and avoid disputes.
Case 10: Fiduciary Contract (
Wadi’ah
- Deposit Taking)
Scenario: Layla deposits jewellery with a custodian, who later uses it for personal gain.
Solution: The custodian has breached trust. Wadi’ah contracts require safekeeping, not personal use. Compensation is due for misuse and any resulting loss.
Conclusion
The Qur’an establishes the sanctity of contracts as both a legal and moral duty. From sales and leases to guarantees and deposits, contracts ensure that wealth and property are exchanged fairly and responsibly. Central to their validity is mutual consent, transparency, and adherence to lawful (halal) terms. The Qur’anic emphasis on fulfilling contracts demonstrates Islam’s vision of building trust, preventing exploitation, and sustaining social order.
Through real-life applications, we see that contracts remain the backbone of Islamic commercial law, guided by divine injunctions and enriched by centuries of juristic reasoning.

KembaraXtra-Islamic Finance: Contracts and the Prophet Muhammad
Introduction
The Sunnah of the Prophet Muhammad (peace be upon him) is not only a moral and spiritual guide but also a legal framework that illustrates the essence of contracts in Islam. While the Qur’an provides broad principles, the Prophet’s sayings and actions (Traditions) clarify, explain, and apply these principles in real-life scenarios. Together, they form the foundation of Islamic commercial law (Fiqh al-Mu‘āmalāt).
One of the Prophet’s well-known sayings is: “The property of a Muslim is not lawful for others to enjoy unless by the owner’s consent.” This teaching establishes the cornerstone of contracts in Islam—the transfer of property, wealth, or services must be based on the true consent of the owner. Any acquisition without valid consent is unlawful and invalid under Shari’ah.
The Prophet’s Traditions act like “case law” in the Islamic legal system, offering numerous examples of what constitutes valid and invalid contracts. For instance, he prohibited the sale of a foetus in an animal’s womb because delivery cannot be guaranteed, thus avoiding gharar (excessive uncertainty). Such rulings reinforce the importance of contracts as a means of ensuring fairness, transparency, and the genuine agreement of all parties involved.
The presence or absence of conditions that affect consent—such as coercion, fraud, or ambiguity—determines whether a contract is valid, void, or voidable. Hence, the Prophetic Traditions remain a living source of guidance for structuring Islamic contracts today.
Case Studies with Solutions
Case 1: Sale of a Foetus in an Animal
Scenario: A farmer sells the unborn calf of a cow to a buyer.
Solution: Invalid. The Prophet prohibited this because delivery cannot be guaranteed, and the foetus may not survive. This falls under gharar (uncertainty), rendering the contract void.
Case 2: Selling What One Does Not Possess
Scenario: A merchant sells grain to a buyer before he has actually purchased or possessed the grain himself.
Solution: Invalid. The Prophet forbade selling goods one does not own or control. The seller must first acquire ownership before entering into a contract.
Case 3: Coerced Sale
Scenario: A wealthy trader pressures a poor man into selling his land far below market value.
Solution: Invalid. Consent must be free and genuine. A coerced sale lacks valid consent, violating the principle expressed by the Prophet that property cannot be lawfully taken without the owner’s approval.
Case 4: Ambiguous Contract in Hire (
Ijarah
)
Scenario: A worker is hired to perform “some tasks” without a clear agreement on the type of work or wages.
Solution: Voidable. The Prophet prohibited contracts with excessive ambiguity (gharar). For validity, the contract must clearly define the work and compensation to prevent exploitation.
Case 5: Honest vs. Dishonest Trade
Scenario: A trader hides defects in his goods and sells them as if they are perfect. Later, the buyer discovers the defect.
Solution: The Prophet declared that deceit in trade invalidates the contract. The buyer has the right to return the item or demand compensation. Honesty is a condition for valid consent and fair dealing.
Conclusion
The Prophet Muhammad’s Traditions serve as practical illustrations of contract law in action. By emphasizing genuine consent, eliminating ambiguity, and prohibiting unjust or deceitful practices, the Sunnah ensures that contracts remain instruments of justice and trust. Whether in sales, leases, or partnerships, the validity of a contract depends on fairness, clarity, and mutual agreement.
These Prophetic teachings continue to shape Islamic finance today, offering timeless principles to guide complex modern transactions while upholding the sanctity of contracts as moral and legal obligations.

KembaraXtra-Islamic Finance: Requirements of a Valid and Enforceable Contract
Introduction
In Islamic commercial law (Fiqh al-Mu‘āmalāt), contracts (‘Aqd) are not merely legal instruments but sacred commitments that bind individuals in financial and social dealings. For a contract to be valid and enforceable, certain fundamental requirements must be met. Classical jurists and contemporary codifications identify six essential elements:
Beyond these six, Islamic law adds a unique and crucial condition: the contract must comply with Shari’ah principles. This means that even if the structural elements of a contract are in order, the purpose, object, or conditions of the contract must not contradict Islamic prohibitions.
These requirements reflect both common sense and divine guidance. In contrast to common law systems, where consideration and the “intention to create legal relations” are central, or civil law systems that emphasize mutual consent, Islamic law insists on a higher moral filter—compliance with divine injunctions. This ensures that contracts are not only legally sound but also ethically and spiritually legitimate.
Case Scenarios with Solutions
Case 1: Missing Offer
Scenario: A customer walks into a shop, sees a product, and pays money without any explicit offer being made by the seller.
Solution: Invalid. A contract requires a clear ijab (offer). Without it, no binding agreement is established.
Case 2: Acceptance with Modification
Scenario: The seller offers to sell a book for $20. The buyer says, “I accept, but I’ll pay $15.”
Solution: Invalid acceptance. This is considered a counter-offer, not acceptance. For validity, the acceptance must match the offer exactly.
Case 3: Unqualified Offeror
Scenario: A minor attempts to sell his father’s car without consent.
Solution: Invalid. The offeror must have legal capacity. A minor cannot independently dispose of property unless acting under guardianship.
Case 4: Unqualified Offeree
Scenario: A mentally incapacitated person agrees to buy land.
Solution: Invalid. The offeree must be legally competent to give valid consent. Contracts entered into by those lacking capacity are void.
Case 5: Defective Object
Scenario: A merchant contracts to sell wine to a non-Muslim buyer.
Solution: Invalid. The subject matter of the contract must be lawful under Shari’ah. Since wine is prohibited, the contract is void regardless of consent.
Case 6: Unclear Object (
Gharar
)
Scenario: A fisherman agrees to sell “whatever fish I catch tomorrow” for a set price.
Solution: Voidable. The object is uncertain, violating the prohibition of gharar. A valid contract requires clear knowledge of the object.
Case 7: Absence of Consideration
Scenario: A man promises to give his neighbour his land without any exchange or specified gift intention.
Solution: Invalid as a contract. Without consideration or clear intention as a gift (hibah), there is no enforceable contract.
Case 8: Lawful Form, Unlawful Purpose
Scenario: Two businessmen form a partnership (shirkah) with the purpose of running a gambling operation.
Solution: Invalid. Even if all six structural elements exist, the unlawful objective makes the contract void under Shari’ah.
Case 9: Conditional Sale That Violates Shari’ah
Scenario: A car is sold on condition that the buyer never uses it for daily prayers transportation.
Solution: Invalid. The condition is unlawful. Contracts with conditions contrary to Shari’ah are voidable.
Case 10: Compliance With All Elements
Scenario: A farmer sells 100 kg of dates to a buyer at an agreed price, specifying quality, quantity, and delivery time. Both offer and acceptance are clear, parties are qualified, and the object is lawful.
Solution: Valid. All six elements plus Shari’ah compliance are satisfied, making the contract enforceable.
Conclusion
A valid and enforceable contract in Islamic law requires more than just mutual consent and clarity. It must meet the six essential elements—offer, acceptance, offeror, offeree, object, and consideration—while also adhering to the overarching principle of Shari’ah compliance. Any missing element or unlawful objective renders the contract invalid or voidable.
Through practical case studies, it becomes clear that Islamic law balances technical structure with moral responsibility, ensuring that contracts are instruments of justice, trust, and ethical exchange in both personal and commercial life.

For a contract to be valid and enforceable, certain fundamental requirements must be met. Classical jurists and contemporary codifications identify six essential elements:

KembaraXtra-Islamic Finance: An Offer
Introduction
In Islamic commercial law, the concept of offer (ijab) represents the first step in the formation of a binding contract. An offer is essentially a declaration of intent by one party (the offeror) inviting the other party (the offeree) to accept the proposal. The offer can originate from either side of a transaction: a buyer proposing to purchase goods or a seller proposing to sell.
The Mejelle (Ottoman Civil Code) provides a technical definition: “The statement made in the first place with a view to making a disposition of property and such disposition is proved thereby.” This definition emphasizes clarity, formality, and communication of the offer. To be valid, the offer must be clear, absolute, and communicated to the intended party.
Some scholars argue that an offer must target a specific party, while others accept a general offer open to anyone, such as public announcements of goods for sale. Islamic jurisprudence, however, distinguishes between a valid offer and an invitation to treat. For instance, displaying goods with price tags or placing advertisements is not itself a contractual offer but an invitation for others to make offers.
This approach aligns with common law principles, as shown in cases like Pharmaceutical Society of Great Britain v. Boots Cash Chemists [1953], where the court ruled that the display of goods was only an invitation to treat, not an offer. Similarly, in Islamic law, the shop owner’s display of goods does not bind him to sell; the true offer emerges only when the buyer proposes to purchase and the seller accepts.
Thus, in both Islamic and conventional law, the offer is foundational: it sets the stage for acceptance, leading to a valid and enforceable contract.
Case Scenarios with Solutions
Case 1: General Offer in a Market
Scenario: A seller announces in a marketplace, “These apples are for sale at $5 per kilo.” A buyer hears this and pays the amount.
Solution: Valid. The announcement constitutes an offer because it includes a specific object and price, and the buyer’s payment signals acceptance.
Case 2: Invitation to Treat in a Shop
Scenario: A clothing store displays shirts with price tags. A customer picks one and brings it to the cashier.
Solution: The display is only an invitation to treat. The customer’s action is the offer, and the sale is finalized when the cashier accepts payment.
Case 3: Ambiguous Offer
Scenario: A seller tells a buyer, “I might sell you my car if the price is right.”
Solution: Invalid. The statement is vague and conditional, lacking the clarity and absoluteness required for a valid offer.
Case 4: Offer to Multiple People
Scenario: A farmer announces, “I will sell my cow for $500 to anyone who pays first.”
Solution: Valid. Islamic law recognizes that a general offer can bind the offeror once someone accepts with payment.
Case 5: Revocation of Offer
Scenario: Ahmad offers to sell his land to Bilal but revokes the offer before Bilal accepts.
Solution: Valid revocation. An offeror may withdraw his offer any time before acceptance, as no binding contract has yet been formed.
Case 6: Acceptance Without Knowledge of Offer
Scenario: A seller posts an online offer to sell goods. A buyer coincidentally sends the same payment amount without seeing the offer.
Solution: Invalid. Acceptance must be based on knowledge of the offer. If the buyer is unaware, no valid contract is formed.
Case 7: Offer with Unlawful Object
Scenario: A trader offers to sell pork to a customer.
Solution: Invalid. Even with clear offer and acceptance, the contract is void since the subject matter is unlawful under Shari’ah.
Case 8: Silence as Acceptance
Scenario: A seller offers to sell a house to a buyer. The buyer remains silent, and the seller assumes acceptance.
Solution: Invalid. Silence does not constitute acceptance in Islamic law unless accompanied by prior conduct indicating agreement.
Case 9: Online Advertisement
Scenario: An e-commerce platform lists goods with prices. A customer clicks “Buy Now.”
Solution: The listing is an invitation to treat. The customer’s click is the offer, and the seller’s confirmation forms the contract.
Case 10: Conditional Offer
Scenario: A businessman offers to sell his car, but only if his partner agrees.
Solution: Voidable. The offer is conditional on a third party’s consent, which creates uncertainty. Until consent is granted, the offer is incomplete.
Conclusion
In Islamic commercial law, an offer (ijab) is the critical starting point of a contract, requiring clarity, definiteness, and lawful intent. While displays and advertisements are considered invitations to treat, a valid offer must reflect a clear statement of intention communicated to the offeree.
Through the scenarios, it becomes evident that the rules around offers safeguard fairness, prevent ambiguity, and align closely with both Shari’ah principles and broader legal traditions. This ensures that contracts are not only legally enforceable but also ethically sound.

Some scholars argue that an offer must target a specific party, while others accept a general offer open to anyone, such as public announcements of goods for sale. Islamic jurisprudence, however, distinguishes between a valid offer and an invitation to treat. For instance, displaying goods with price tags or placing advertisements is not itself a contractual offer but an invitation for others to make offers.
This approach aligns with common law principles, as shown in cases like Pharmaceutical Society of Great Britain v. Boots Cash Chemists [1953], where the court ruled that the display of goods was only an invitation to treat, not an offer. Similarly, in Islamic law, the shop owner’s display of goods does not bind him to sell; the true offer emerges only when the buyer proposes to purchase and the seller accepts.
Thus, in both Islamic and conventional law, the offer is foundational: it sets the stage for acceptance, leading to a valid and enforceable contract.
Case Scenarios with Solutions
Case 1: General Offer in a Market
Scenario: A seller announces in a marketplace, “These apples are for sale at $5 per kilo.” A buyer hears this and pays the amount.
Solution: Valid. The announcement constitutes an offer because it includes a specific object and price, and the buyer’s payment signals acceptance.
Case 2: Invitation to Treat in a Shop
Scenario: A clothing store displays shirts with price tags. A customer picks one and brings it to the cashier.
Solution: The display is only an invitation to treat. The customer’s action is the offer, and the sale is finalized when the cashier accepts payment.
Case 3: Ambiguous Offer
Scenario: A seller tells a buyer, “I might sell you my car if the price is right.”
Solution: Invalid. The statement is vague and conditional, lacking the clarity and absoluteness required for a valid offer.
Case 4: Offer to Multiple People
Scenario: A farmer announces, “I will sell my cow for $500 to anyone who pays first.”
Solution: Valid. Islamic law recognizes that a general offer can bind the offeror once someone accepts with payment.
Case 5: Revocation of Offer
Scenario: Ahmad offers to sell his land to Bilal but revokes the offer before Bilal accepts.
Solution: Valid revocation. An offeror may withdraw his offer any time before acceptance, as no binding contract has yet been formed.
Case 6: Acceptance Without Knowledge of Offer
Scenario: A seller posts an online offer to sell goods. A buyer coincidentally sends the same payment amount without seeing the offer.
Solution: Invalid. Acceptance must be based on knowledge of the offer. If the buyer is unaware, no valid contract is formed.
Case 7: Offer with Unlawful Object
Scenario: A trader offers to sell pork to a customer.
Solution: Invalid. Even with clear offer and acceptance, the contract is void since the subject matter is unlawful under Shari’ah.
Case 8: Silence as Acceptance
Scenario: A seller offers to sell a house to a buyer. The buyer remains silent, and the seller assumes acceptance.
Solution: Invalid. Silence does not constitute acceptance in Islamic law unless accompanied by prior conduct indicating agreement.
Case 9: Online Advertisement
Scenario: An e-commerce platform lists goods with prices. A customer clicks “Buy Now.”
Solution: The listing is an invitation to treat. The customer’s click is the offer, and the seller’s confirmation forms the contract.
Case 10: Conditional Offer
Scenario: A businessman offers to sell his car, but only if his partner agrees.
Solution: Voidable. The offer is conditional on a third party’s consent, which creates uncertainty. Until consent is granted, the offer is incomplete.
Conclusion
In Islamic commercial law, an offer (ijab) is the critical starting point of a contract, requiring clarity, definiteness, and lawful intent. While displays and advertisements are considered invitations to treat, a valid offer must reflect a clear statement of intention communicated to the offeree.
Through the scenarios, it becomes evident that the rules around offers safeguard fairness, prevent ambiguity, and align closely with both Shari’ah principles and broader legal traditions. This ensures that contracts are not only legally enforceable but also ethically sound.

KembaraXtra-Islamic Finance – Accepting an Offer
Introduction
In Islamic finance, the validity of a contract rests on the principles of offer (ijab) and acceptance (qabul). Acceptance is the clear and unconditional approval of the offeror’s proposal by the offeree. For a contract to be binding, acceptance must mirror the offer in all respects. If any changes are made, it transforms the acceptance into a counter-offer requiring fresh approval.
This ensures fairness, transparency, and the establishment of mutual consent (ittihad al-iradat), also known as the “meeting of minds.” Islam emphasizes lawful trade, free from exploitation, coercion, or ambiguity (gharar). The Qur’an reminds:
“…O you who have believed, do not consume one another’s wealth unjustly but only [in lawful] business by mutual consent…” (Surah An-Nisa, 4:29)
Acceptance must also be communicated clearly, whether through words, writing, or actions. Without such communication, no valid contract is formed.

Acceptance must also be communicated clearly, whether through words, writing, or actions. Without such communication, no valid contract is formed.
Explanation
- Exact Conformity: Acceptance must fully align with the offer. Any deviation creates a new proposal.
- Counter-Offer Principle: When terms are altered, the original offer is void, and negotiation continues until consensus is reached.
- Communication Requirement: Silent approval or unexpressed decisions have no legal effect. The Prophet ﷺ said:
“The two parties to a transaction have the option (to confirm or cancel) as long as they have not separated.” (al-Bukhari, Muslim) - Modes of Expression: Acceptance may be verbal, written, or implied through conduct, including modern communication tools such as emails and digital platforms.
- Shari’ah Compliance: Acceptance must be free of deceit (tadlis), coercion, or uncertainty (gharar), ensuring clarity and trust between parties.
Case Scenarios
- Email Acceptance in a Murabahah Agreement
A bank offers a Murabahah contract. The client responds via email: “I accept all terms as stated.”
→ Valid acceptance since it mirrors the offer and is communicated clearly. - Verbal Acceptance in Ijarah (Leasing)
A company offers to lease equipment. The lessee states over the phone: “I agree to your offer exactly as presented.”
→ Clear verbal communication makes the acceptance binding. - Counter-Offer in Musharakah (Partnership)
An investor proposes a $50,000 partnership. The offeree replies: “I accept, but I can only contribute $30,000.”
→ This is a counter-offer, not acceptance, requiring the offeror’s new consent. - Conduct as Acceptance in a Mudarabah Contract
A financier offers to fund a venture. The entrepreneur, without verbal reply, begins using the funds in accordance with the terms.
→ Their conduct is deemed acceptance, validating the contract. - Uncommunicated Acceptance in Wakalah (Agency Agreement)
A principal offers an agency contract. The prospective agent privately agrees in his heart but never communicates it.
→ No valid contract arises since acceptance must be conveyed.
Shari’ah Insights
- Email Acceptance (Murabahah)
- Qur’an: “…fulfill [every] commitment. Indeed, the commitment is ever [that about which one will be] questioned.” (Surah Al-Isra, 17:34)
- Legal Maxim: “Certainty is not removed by doubt” (al-yaqin la yazulu bil-shakk) → Clear, documented email acceptance removes any uncertainty.
- Verbal Acceptance (Ijarah)
- Hadith: “The Muslims are bound by their conditions…” (Abu Dawud, Tirmidhi)
- Legal Maxim: “Custom is an arbitrator” (al-ʿadah muhakkamah) → Verbal contracts are binding in many cultures, making this valid.
- Counter-Offer (Musharakah)
- Qur’an: “…do not devour one another’s wealth unjustly…” (Surah Al-Baqarah, 2:188)
- Insight: A counter-offer ensures no party is forced into terms they cannot meet, protecting fairness.
- Conduct as Acceptance (Mudarabah)
- Hadith: “Actions are but by intentions…” (al-Bukhari, Muslim)
- Legal Maxim: “Matters are judged by their objectives” (al-umūr bi maqāsidiha) → Using the funds according to agreed terms reflects genuine acceptance.
- Uncommunicated Acceptance (Wakalah)
- Qur’an: “…and do not conceal testimony, for whoever conceals it – his heart is indeed sinful…” (Surah Al-Baqarah, 2:283)
- Insight: Acceptance must be disclosed; silence or concealment has no effect in Shari’ah.
