Islamic Contract Law – Bargain Theory (English Law) Comparison


1. What is Bargain Theory? (English Law)
  • A contract is based on a bargain (exchange) between parties
  • Each party must:
    • Give something
    • Receive something in return
👉 This “something” is called consideration


Simple Example
  • A sells a laptop to B for RM1000
  • A gives: laptop
  • B gives: RM1000
👉 This exchange = bargain → valid contract


2. Key Features of Bargain Theory
  • Focus on:
    • Exchange of value
  • Requires:
    • Consideration
  • Principle:
    • “No consideration = no contract”
  • Law is concerned with:
    • What is exchanged, not morality


3. Examples of Bargain Theory
a. Sale Contract
  • Goods exchanged for money
  • Profit comes from:
    • Price difference


b. Service Contract
  • Work/services exchanged for payment


c. Debt Agreement
  • Loan given → repayment promised


4. What is NOT a Bargain (in English Law)
  • Pure promise:
    • “I will give you RM1000” ❌
  • No exchange → no consideration
👉 Not a valid contract (unless formalised as a deed)


5. Comparison with Islamic Contract Law
A. Core Foundation
  • Bargain Theory (English Law)
    • Based on:
      • Exchange (consideration)
  • Islamic Contract Law
    • Based on:
      • Fulfilment of obligations
      • Moral + legal duty


B. Role of Consideration
  • English Law
    • Essential requirement
  • Islamic Contract Law
    • Not required in the same strict sense
    • Focus is on:
      • Consent
      • Lawful subject matter


C. Treatment of Promises
  • English Law
    • Not binding without consideration
  • Islamic Contract Law
    • Can be binding:
      • Morally
      • Sometimes legally


D. Focus of the System
  • English Law
    • Economic exchange
    • Legal enforceability
  • Islamic Contract Law
    • Ethical responsibility
    • Justice and fairness


6. Key Difference (Very Important)
  • Bargain Theory
    • Contract = exchange of value
  • Islamic Contract Law
    • Contract = binding obligation that must be fulfilled


Final Summary
  • Bargain theory explains contracts as:
    • Mutual exchange (consideration-based)
  • Islamic contract law is broader:
    • Includes:
      • Exchange-based contracts
      • Non-exchange obligations (promises, covenants, oaths)


One-Line Comparison
  • Bargain theory = “You give something, I give something”
  • Islamic contract law = “Once you commit, you must fulfil”


If you want, we can move next to will theory—it’s another key comparison often asked in exams.

Islamic Contract Law – Moral Injunctions vs Legally Binding Principles 


1. Basic Distinction
  • Important to distinguish between:
    • Moral injunctions → ethical guidance (right vs wrong)
    • Legally binding principles → enforceable legal rules
👉 However:
  • In Islamic law, the line is not always clear


2. Why the Line is Blurred
  • Islamic law is based on:
    • Qurʾān
    • Sunnah
  • These sources contain:
    • Commands
    • Prohibitions
    • Moral teachings
👉 Some rules are:
  • Clearly legal
  • Others are:
    • Moral but may influence legal rulings


3. Indicators of Legally Binding Rules
  • Imperative form (command language)
    • Example:
      • “Fulfil your contracts”
    • Indicates:
      • Legal obligation


  • Past tense used as command
    • Sometimes Arabic uses:
      • Past tense to imply obligation
    • Still indicates:
      • Binding rule


4. Moral Rules Becoming Legal Rules
  • Some actions are:
    • Initially morally condemned
  • But over time:
    • Become legally prohibited


Examples
  • Dishonesty in trade
    • Moral teaching:
      • Be truthful
    • Legal effect:
      • Fraud → contract can be invalid


  • Unfair dealing
    • Moral issue:
      • Exploitation is wrong
    • Legal effect:
      • May invalidate or affect contract


5. Commands via Consequences
  • Sometimes rules are expressed indirectly:
    • By stating consequences of actions


Example
  • If a text says:
    • “Those who cheat will be punished”
👉 Implies:
  • Cheating is:
    • Prohibited
    • Can affect legal validity


6. Application in Contract Law
  • Contracts must avoid:
    • Prohibited elements
    • Morally condemned behaviour
  • Because:
    • Moral violations can lead to:
      • Legal consequences


7. Key Insight
  • In Islamic contract law:
    • Law and morality are closely connected
👉 Unlike some legal systems:
  • Where law and morality are separated


Final Summary
  • Moral injunctions = ethical guidance
  • Legal principles = binding rules
  • BUT:
    • In Islamic law:
      • Moral teachings can become legal obligations
      • The boundary between them is sometimes blurred


One-Line Understanding
  • Islamic law =
    “Morality can shape law, and law reinforces morality.”

​Islamic Contract Law – Will Theory (English Law) Comparison


1. What is Will Theory? (English Law)
  • Contract is based on the free will (intention) of the parties
  • Emphasises:
    • Freedom of contract
    • Parties are free to decide:
      • Whether to contract
      • Terms of the contract
👉 Key idea:
  • A contract is binding because parties intended it


Simple Example
  • A and B agree:
    • A sells a car for RM5,000
  • Both willingly agree
👉 Contract is valid because:
  • There is mutual intention (meeting of minds)


2. Key Features of Will Theory
  • Focus on:
    • Consent and intention
  • Emphasises:
    • Freedom
    • Autonomy of parties
  • Law respects:
    • What parties choose to agree on


3. Examples of Will Theory
a. Negotiated Contract
  • Parties freely negotiate terms
  • Example:
    • Price, delivery, conditions


b. Customised Agreements
  • Parties create their own terms
  • Law enforces:
    • Their chosen arrangement


c. Business Deals
  • Companies structure contracts based on:
    • Mutual consent and interests


4. Limitations of Will Theory
  • Freedom is not absolute
  • Law may restrict contracts involving:
    • Illegality
    • Fraud
    • Misrepresentation
    • Unfairness


5. Comparison with Islamic Contract Law
A. Core Foundation
  • Will Theory (English Law)
    • Contract based on:
      • Intention and consent
  • Islamic Contract Law
    • Based on:
      • Consent + obligation to fulfil
      • Moral and legal responsibility


B. Freedom of Contract
  • English Law
    • Strong emphasis on:
      • Freedom to contract
  • Islamic Contract Law
    • Freedom exists but is:
      • Limited by Shariah principles
    • Must avoid:
      • Riba (interest)
      • Gharar (excessive uncertainty)
      • Unlawful subject matter


C. Role of Morality
  • English Law
    • Focus on:
      • Legal validity
  • Islamic Contract Law
    • Combines:
      • Legal + ethical + religious values


D. Binding Nature
  • Will Theory
    • Binding because:
      • Parties intended it
  • Islamic Contract Law
    • Binding because:
      • Parties agreed
      • And must fulfil obligations as a duty


6. Key Difference (Very Important)
  • Will Theory
    • Contract = expression of free will
  • Islamic Contract Law
    • Contract = binding commitment governed by law and morality


Final Summary
  • Will theory focuses on:
    • Freedom and intention of parties
  • Islamic contract law:
    • Accepts intention
    • But adds:
      • Moral responsibility
      • Religious accountability
      • Substantive limits (Shariah rules)


One-Line Comparison
  • Will theory = “What parties intend becomes law”
  • Islamic contract law = “What parties agree must be lawful and fulfilled”
