Islamic Contract Law – Sanctity of Contract (ʿUqūd) in Islam 

1. Qurʾānic Foundation
  • Principle based on the verse:
    • “O you who have believed! Fulfil your undertakings”
  • The term used:
    • ʿUqūd (plural of ʿaqd = contracts/commitments)
👉 Meaning:
  • All binding commitments must be honoured


2. Meaning of Sanctity of Contract
  • Contracts are:
    • Sacred and binding
  • Parties must:
    • Fulfil obligations faithfully
  • Not just legal duty, but also:
    • Moral and religious duty


3. Scope of the Principle (Very Important)
  • Applies broadly to:
    • Commercial contracts
    • Personal promises
    • Social obligations
    • Religious commitments
👉 Not limited to business transactions


4. Application in Different Contexts (with Examples)
a. Commercial Contracts
  • Example:
    • Sale agreement → must deliver goods and pay price
  • Obligation:
    • Both parties must honour the terms


b. Personal Agreements
  • Example:
    • “I promise to repay you next week”
  • Obligation:
    • Must fulfil the promise


c. Social Commitments
  • Example:
    • Agreement to sponsor a student
  • Obligation:
    • Expected to honour the commitment


d. Religious Covenant (ʿAhd with God)
  • Example:
    • Performing prayers, fasting
  • Seen as:
    • A covenant between الإنسان and God
👉 This is not a commercial contract but still falls under ʿuqūd


5. Link to ʿAqd al-ʿAhd
  • The concept of ʿahd (covenant):
    • Extends the idea of contract to:
      • Spiritual and moral obligations
  • Example:
    • Commitment to obey God
    • Fulfilling religious duties


6. Key Principle
  • In Islamic law:
    • Breaking a contract = breach of legal + moral duty
  • Emphasis on:
    • Honesty
    • Trustworthiness
    • Accountability


Final Summary
  • ʿUqūd (contracts/commitments) must be fulfilled
  • The sanctity of contract:
    • Applies to all types of obligations
    • Not limited to commercial dealings
👉 Includes:
  • Legal contracts
  • Promises
  • Covenants with God


One-Line Understanding

Islamic Contract Law – Development of Contract Theory (Notes)


1. Nature of Early Islamic Jurisprudence
  • Early Muslim jurists focused on:
    • Practical interpretation of law
    • Not abstract theorising
  • Legal principles were developed through:
    • Interpretation of sources (Qurʾān, Sunnah)
    • Real-life cases
👉 Result:
  • Law evolved as a practical system, not a theoretical model


2. Absence of a Formal Contract Theory
  • Early jurists:
    • Did not formally define “contract” (ʿaqd)
    • Did not develop a systematic theory of contract law
  • Instead:
    • Focused on:
      • Rules of specific transactions (sale, lease, etc.)


3. Underlying Principle (Core Idea)
  • The foundation of Islamic contract law is:
    • Fulfilment of obligations
👉 Key idea:
  • Once a commitment is made → it must be honoured


4. Moral Basis of the Theory
  • Initially based on:
    • Moral and ethical persuasion
  • Emphasis on:
    • Honesty
    • Trust
    • Accountability
  • Example:
    • A promise to repay a debt is binding because:
      • It is morally wrong to break it


5. Later Development (Textual Support)
  • Muslim jurists later reinforced this principle using:
    • Qurʾānic evidence (e.g., fulfil your contracts)
    • Prophetic teachings
👉 This gave:
  • Legal authority to what began as moral principles


6. Key Features of Islamic Contract Theory
  • Not abstract or theoretical in origin
  • Built on:
    • Practical rulings + moral values
  • Focus on:
    • Obligation and fulfilment, not just formation


Final Summary
  • Islamic contract law did not start as a formal theory
  • It developed from:
    • Practical legal interpretation
    • Strong moral emphasis on fulfilling obligations
  • Later:
    • Supported by textual evidence, making it legally binding


One-Line Understanding
  • Islamic contract law =
    “A practical system built on the moral and legal duty to fulfil obligations.”
