SurahAl-MuṭaffifīnMedinan/MeccanCommercial fraud prohibition the sole surah dedicated to a commercial prohibition

Key Fiqh IssueTaṭfīf shortchanging buyers in weights and measuresḤarām by definitive naṣṣInvalidates or makes voidable the transaction when material

School ComparisonḤanafī: material shortfall creates khiyār (option to cancel) for buyer; Mālikī: shortfall = fasād al-ʿaqd (contract corruption); Shāfiʿī: same khiyār approach; Ḥanbalī: strict disclosure obligationḤarām / Transaction remedy availableBuyer's remedy protects commercial trust

Uṣūl PrincipleḤurmat al-ghishsh prohibition of commercial fraud as a universal Islamic commercial principleḥarāmHonesty in measurement is a religious obligation, not merely commercial ethics

Al-Qurṭubī notes that this surah is unique in being dedicated entirely to a commercial prohibition underscoring the severity of fraud in measurement. Verses 1-3 define the offence with precision: taking full measure when receiving, but giving short measure when selling. The divine condemnation ("waylun" woe!) is the most severe Qurʾānic warning formula, establishing taṭfīf as among the gravest commercial sins.

Al-Qurṭubī maps the legal remedies: when a buyer discovers shortchanging, they have khiyār al-ʿayb (option due to defect) they can cancel the transaction and demand full measure or compensation. The Mālikī classification of severe taṭfīf as fasād al-ʿaqd (contract corruption) is the strongest position it treats material fraud as voiding the contract rather than merely giving the buyer an option. Al-Qurṭubī derives the principle ḥurmat al-ghishsh (prohibition of commercial deception) as a universal maxim extending to all forms of commercial misrepresentation, not just measurement fraud.

وَيْلٌ لِّلْمُطَفِّفِينَ الَّذِينَ إِذَا اكْتَالُوا عَلَى النَّاسِ يَسْتَوْفُونَ وَإِذَا كَالُوهُمْ أَو وَّزَنُوهُمْ يُخْسِرُونَ Waylun li-l-muṭaffifīna lladhīna idhā ktālū ʿalā l-nāsi yastawfūna wa-idhā kālūhum aw wazanūhum yukhsirūn Meaning: "Woe to the defrauders those who, when they take a measure from people, take full and when they give by measure or weight to them, give less" Al-Qurṭubī: the precise definition captures the hypocrisy of selective honesty: demanding full measure for oneself while shortchanging others; the condemnation is not of inaccuracy but of deliberate, self-serving fraud.

أَلَا يَظُنُّ أُولَٰئِكَ أَنَّهُم مَّبْعُوثُونَ لِيَوْمٍ عَظِيمٍ Alā yaẓunnu ūlāʾika annahum mabʿūthūna li-yawmin ʿaẓīm Meaning: "Do they not think that they will be resurrected for a mighty day?" Al-Qurṭubī: the rhetorical question links commercial fraud to the denial of accountability; al-Qurṭubī derives that iman (belief) in the Day of Judgment and commercial honesty are causally linked believers cannot simultaneously believe in divine accountability and engage in deliberate commercial fraud.

Taṭfīf (shortchanging in weights and measures) is ḥarām by definitive Qurʾānic text the "waylun" warning is the most severe condemnation formula.
Material shortchanging creates khiyār al-ʿayb (option to cancel) for the defrauded buyer all four schools provide this remedy.
Mālikī school treats severe fraud as fasād al-ʿaqd (contract corruption) the contract is void rather than merely voidable.
The ḥurmat al-ghishsh principle extends beyond measurement: all commercial misrepresentation (quality fraud, defect concealment, false advertising) is ḥarām by analogy.
Belief in accountability and commercial honesty are causally linked in al-Qurṭubī's analysis the defrauder's conduct reveals a deficiency in their iman in divine reckoning.
