Al-Baqarah 2:282 يا ايها الذين امنوا اذا تداينتم بدين الى اجل مسمى فاكتبوه وليكتب بينكم كاتب بالعدل ولا ياب كاتب ان يكتب كما علمه الله فليكتب وليملل الذي عليه الحق وليتق الله ربه ولا يبخس منه شييا فان كان الذي عليه الحق سفيها او ضعيفا او لا يستطيع ان يمل هو فليملل وليه بالعدل واستشهدوا شهيدين من رجالكم فان لم يكونا رجلين فرجل وامراتان ممن ترضون من الشهداء ان تضل احداهما فتذكر احداهما الاخرى ولا ياب الشهداء اذا ما دعوا ولا تساموا ان تكتبوه صغيرا او كبيرا الى اجله ذالكم اقسط عند الله واقوم للشهادة وادنى الا ترتابوا الا ان تكون تجارة حاضرة تديرونها بينكم فليس عليكم جناح الا تكتبوها واشهدوا اذا تبايعتم ولا يضار كاتب ولا شهيد وان تفعلوا فانه فسوق بكم واتقوا الله ويعلمكم الله والله بكل شيء عليم ٢٨٢

O ye who believe! When ye contract a debt for a fixed term, record it in writing. Let a scribe record it in writing between you in (terms of) equity. No scribe should refuse to write as Allah hath taught him, so let him write, and let him who incurreth the debt dictate, and let him observe his duty to Allah his Lord, and diminish naught thereof. But if he who oweth the debt is of low understanding, or weak, or unable himself to dictate, then let the guardian of his interests dictate in (terms of) equity. And call to witness, from among your men, two witnesses. And if two men be not (at hand) then a man and two women, of such as ye approve as witnesses, so that if the one erreth (through forgetfulness) the other will remember. And the witnesses must not refuse when they are summoned. Be not averse to writing down (the contract) whether it be small or great, with (record of) the term thereof. That is more equitable in the sight of Allah and more sure for testimony, and the best way of avoiding doubt between you; save only in the case when it is actual merchandise which ye transfer among yourselves from hand to hand. In that case it is no sin for you if ye write it not. And have witnesses when ye sell one to another, and let no harm be done to scribe or witness. If ye do (harm to them) lo! it is a sin in you. Observe your duty to Allah. Allah is teaching you. And Allah is knower of all things.

O you who have believed, when you contract a debt for a specified term, write it down. And let a scribe write [it] between you in justice. Let no scribe refuse to write as Allāh has taught him. So let him write and let the one who has the obligation [i.e., the debtor] dictate. And let him fear Allāh, his Lord, and not leave anything out of it. But if the one who has the obligation is of limited understanding or weak or unable to dictate himself, then let his guardian dictate in justice. And bring to witness two witnesses from among your men. And if there are not two men [available], then a man and two women from those whom you accept as witnesses - so that if one of them [i.e., the women] errs, then the other can remind her. And let not the witnesses refuse when they are called upon. And do not be [too] weary to write it, whether it is small or large, for its [specified] term. That is more just in the sight of Allāh and stronger as evidence and more likely to prevent doubt between you, except when it is an immediate transaction which you conduct among yourselves. For [then] there is no blame upon you if you do not write it. And take witnesses when you conclude a contract. Let no scribe be harmed or any witness. For if you do so, indeed, it is [grave] disobedience in you. And fear Allāh. And Allāh teaches you. And Allāh is Knowing of all things.

O ye who believe! When ye deal with each other, in transactions involving future obligations in a fixed period of time, reduce them to writing Let a scribe write down faithfully as between the parties: let not the scribe refuse to write: as Allah Has taught him, so let him write. Let him who incurs the liability dictate, but let him fear His Lord Allah, and not diminish aught of what he owes. If they party liable is mentally deficient, or weak, or unable Himself to dictate, Let his guardian dictate faithfully, and get two witnesses, out of your own men, and if there are not two men, then a man and two women, such as ye choose, for witnesses, so that if one of them errs, the other can remind her. The witnesses should not refuse when they are called on (For evidence). Disdain not to reduce to writing (your contract) for a future period, whether it be small or big: it is juster in the sight of Allah, More suitable as evidence, and more convenient to prevent doubts among yourselves but if it be a transaction which ye carry out on the spot among yourselves, there is no blame on you if ye reduce it not to writing. But take witness whenever ye make a commercial contract; and let neither scribe nor witness suffer harm. If ye do (such harm), it would be wickedness in you. So fear Allah; For it is Good that teaches you. And Allah is well acquainted with all things.
