Kembaraxtra – Islamic Finance: Common Unilateral Contracts in Practice
Introduction
In Islamic commercial law, contracts are generally classified into two categories: bilateral (mu‘awadat), which involve an exchange, and unilateral (tabarru‘at), which involve acts of donation, concession, or benevolence. While bilateral contracts dominate trade and commerce, unilateral contracts are equally important because they promote compassion, social justice, and ethical dealings in society.
Some of the most common unilateral contracts include:
1. Wasiyyah (Will): A person leaves a will in favour of a beneficiary who is not already entitled to inherit under the Qur’anic rules of inheritance. The will cannot exceed one-third of the estate, ensuring fairness to rightful heirs.
2. Tanāzul (Waiver): A person voluntarily gives up their right or entitlement, either during negotiations or as an upfront clause. For example, an investor may waive excess returns to a fund manager as an incentive.
3. Ibrā’ (Rebate/Discount): A creditor forgives or reduces part of a debt, often when a debtor settles early. In Shari’ah, this rebate must be voluntary; pre-agreed rebates are not permissible because they create uncertainty (gharar) in the sale price.
These contracts highlight Islam’s emphasis on generosity, fairness, and transparency. They not only regulate financial transactions but also cultivate trust, compassion, and accountability.
Five Case Scenarios with Solutions
Case 1: Will Beyond the One-Third Limit
• Scenario: Ahmad writes a will leaving half of his estate to his friend. His children object.
• Solution: The Qur’an (An-Nisa’ 4:11-12) fixes heirs’ shares clearly. A will cannot exceed one-third of the estate to non-heirs. Ahmad’s will is valid only up to one-third, and the rest must go to heirs.
• Hadith: The Prophet ﷺ said: “Allah has given every rightful person his right, so there is no bequest for an heir.” (Sunan Abi Dawud 2870).
Case 2: Waiver of Profit Share
• Scenario: Fatimah invests in a Shari’ah-compliant fund. The fund earns higher profits than expected. She agrees upfront to waive extra profit above a set threshold to reward the fund manager.
• Solution: This is valid because waiver (tanāzul) is her voluntary choice. It incentivises the manager without injustice.
• Qur’an: “And give full measure and weight in justice…” (Al-An‘am 6:152).
Case 3: Ibra’ on Early Loan Repayment
• Scenario: Yusuf owes RM10,000 to an Islamic bank but settles early. The bank voluntarily grants him a rebate of RM1,000.
• Solution: This is permissible because the rebate was discretionary, not pre-agreed. If it had been pre-fixed in the contract, it would cause uncertainty in the selling price.
• Qur’an: “But if the debtor is in difficulty, then postpone until a time of ease. But if you give from your right as charity, then it is better for you, if you only knew.” (Al-Baqarah 2:280).
Case 4: Waiver to Avoid Conflict
• Scenario: Two business partners disagree over profit distribution. One partner waives part of his share to preserve their friendship and continue the business.
• Solution: This voluntary waiver avoids dispute and strengthens the relationship.
• Hadith: The Prophet ﷺ said: “The best among you are those who are best to their companions.” (Sunan al-Tirmidhi 1162).
Case 5: Wasiyyah to Non-Muslim Neighbour
• Scenario: Ali wishes to leave part of his wealth to his non-Muslim neighbour who always supported him.
• Solution: This is valid as long as it does not exceed one-third of the estate and does not harm the rights of heirs.
• Qur’an: “Allah does not forbid you from being kind and just to those who do not fight you because of religion nor drive you out of your homes…” (Al-Mumtahanah 60:8).
Critical Analysis
Unilateral contracts in Islam serve an essential role in balancing strict commercial rules with compassion and ethical flexibility. By limiting wills to one-third for non-heirs, Islam protects heirs’ rights while allowing space for generosity. Waivers and rebates ensure that contracts remain fair and flexible without introducing uncertainty.
Critics argue that prohibiting pre-agreed rebates reduces efficiency in modern banking, as customers prefer clarity. However, Shari’ah prioritises certainty (qat‘iyyah) and fairness over convenience to prevent exploitation.
In practice, unilateral contracts bridge gaps between rigid legal obligations and human realities. They foster trust, reduce disputes, and encourage social solidarity—values embedded in both Qur’an and Sunnah.
Conclusion
Unilateral contracts such as wasiyyah, tanāzul, and ibrā’ reflect the ethical spirit of Islamic finance: balancing rights with compassion, certainty with flexibility, and law with morality. They provide a Shari’ah-compliant way to deal with death, debt, and business relationships, ensuring justice while cultivating goodwill.
