فِقهُ العَقدِ وَالشُّرُوط — العُقُودُ وَالشُّرُوطُ فِي الفِقهِ الإِسلَامِيّ: العَنَاصِرُ الأَسَاسِيَّةُ الَّتِي تُصَحِّحُ العَقدَ وَأَنوَاعُ الشُّرُوطِ القَابِلَةِ لِلتَّطبِيقِ وَالمُبطِلَةِ وَالمَبدَأُ الشَّامِلُ بِأَنَّ العُقُودَ مُبَاحَةٌ مَا لَم تُحظَر
Fiqh al-Aqd wal-Shurut (فِقهُ العَقدِ وَالشُّرُوط — Jurisprudence of Contracts and Conditions; *'aqd*: contract, lit. a knot or tie; *shart* [pl. shurut]: condition, stipulation; the default rule: the Hanbali principle — 'the default in contracts is permissibility unless there is evidence of prohibition' [al-asl fi al-'uqud al-ibaha illa ma dalla al-dalil 'ala tahrimihi]; the Shafi'i/Hanafi alternative: 'the default in 'ibadat is prohibition and in 'adat [custom/transactions] permissibility' — effectively the same result for contracts; the essential elements [arkan] of a valid contract: [1] 'aqidan [two contracting parties]: both must be: mukallaf [legally competent: adult, sane, not under legal incapacity]; rida [willing: no coercion]; [2] mahall al-'aqd [subject matter]: must be: mawjud [existing or achievable]; ma'lum [known/identified: not excessive gharar/uncertainty]; qabil lil-tasarruf [susceptible to legal disposition]; lawful; [3] sighah [form/offer-and-acceptance]: ijab [offer] + qabul [acceptance]; must be: mutatabi'an [sequential]; mutawafiqan [matching in material terms]; the principle of qabul matching ijab means: if the offer says 'I sell for 100' and acceptance says 'I accept for 90' — no contract; types of conditions: [1] shart sahih [valid condition]: any condition that does not contradict the essence of the contract and is not prohibited; example: seller conditions on installment payment — valid; [2] shart fasid [corrupt condition]: violates the contract's essential nature or is Islamically prohibited; example: condition that riba [interest] be paid on late payment — fasid; but debate: does a fasid shart invalidate the whole contract or just itself? Hanafi position: the condition is invalid but the contract stands [if the condition doesn't fundamentally alter the contract's nature]; Shafi'i position: a fasid shart typically voids the contract; Hanbali position: closer to Shafi'i; [3] shart mubah [permissible condition]: any condition that the parties agree to and that doesn't contravene the above; the wide Hanbali permissibility of conditions: Ibn Taymiyya's principle that 'Muslims are bound by their conditions' [al-muslimun 'inda shurутihim] allows parties to customize contracts extensively; modern Islamic commercial contracts: sophisticated contracts used in Islamic finance [sukuk, murabahah, ijarah] often use multiple layered conditions; structuring teams must analyze each condition under the applicable school's framework; AAOIFI sharia standards analyze conditions extensively for compliance) is the foundational framework for all Islamic commercial agreements.
The Default Permissibility Principle
Islamic contract law begins from a fundamentally different starting point than many historical legal systems. The Hanbali principle — that the default in transactions is permissibility unless there is specific prohibitory evidence — means that commercial creativity is presumed valid. You don’t need to find a positive permission for a new commercial arrangement; you need to find a prohibition to exclude it.
This contrasts with the ‘ibada (ritual worship) domain, where the default is prohibition: you cannot introduce new ritual practices without specific authorization. The contract domain is more flexible, because economic life generates endless new arrangements that the classical jurists could not anticipate.
The Offer-Acceptance Matching Requirement
The sighah requirement — that offer and acceptance must match in all material terms — is a crucial source of commercial dispute. If a buyer says “I accept for 90” when the seller offered for 100, classical doctrine says there is no contract. The divergence in terms means the parties haven’t yet agreed.
Modern commercial practice handles this with careful drafting — the parties must ensure that acceptance is unequivocal and matches all material terms, or that any counter-offer is clearly labeled as such (generating a new offer that the other party can accept).
The Condition Classification Challenge
The most practically significant questions in Islamic contract law involve conditions: when does a contractual condition become void-making? The schools diverge on the key question of whether a corrupt condition voids the whole contract or just the condition itself.
For Islamic finance structuring: Hanafi flexibility on conditions — the contract survives even if a condition is removed — makes Hanafi-based jurisdictions (Pakistan, much of Central Asia) more amenable to complex conditional structures than Shafi’i-based ones.
