“O YOU who have attained to faith! Whenever you give or take credit for a stated term, set it down in writing. And let a scribe write it down equitably between you; and no scribe shall refuse to write as God has taught him: thus shall he write. And let him who contracts the debt dictate; and let him be conscious of God, his Sustainer, and not weaken anything of his undertaking. And if he who contracts the debt is weak of mind or body, or, is not able to dictate himself, then let him who watches over his interests dictate equitably. And call upon two of your men to act as witnesses; and if two men are not available, then a man and two women from among such as are acceptable to you as witnesses, so that if one of them should make a mistake, the other could remind her. And the witnesses must not refuse [to give evidence] whenever they are called upon. And be not loath to write down every contractual provision, be it small or great, together with the time at which it falls due; this is more equitable in the sight of God, more reliable as evidence, and more likely to prevent you from having doubts [later]. If, however, [the transaction] concerns ready merchandise which you transfer directly unto one another, you will incur no sin if you do not write it down. And have witnesses whenever you trade with one another, but neither scribe nor witness must suffer harm; for if you do [them harm], behold, it will be sinful conduct on your part. And remain conscious of God, since it is God who teaches you [herewith] - and God has full knowledge of everything.”

Allah then taught them what they ought to learn in their dealings, saying: (O ye who believe!) in Allah and His Messenger (when ye contract a debt for a fixed term, record it) i.e. the debt (in writing. Let a scribe record it in writing between you) the indebted person and the creditor (in (terms of) equity) justice. (No scribe should refuse to write) the contract between the creditor and the debtor (as Allah hath taught him) how to write, (so let him write) the contract without addition or omission, (and let him who incurreth the debt dictate) i.e. the indebted person should explain to the scribe the debt he owes, (and let him observe his duty to Allah his Lord) let the indebted person fear his Lord, (and diminish naught thereof) and not diminish any amount of debt he owes upon dictation. (But if he who oweth the debt is of low understanding) is ignorant of dictation, (or weak) unable to dictate, (or unable himself to dictate) does not know how to dictate to the scribe, (then let the guardian of his interests dictate) the guardian of his wealth who is the creditor (in (terms of) equity) without any addition. (And call to witness) for your rights, (from among your men, two witnesses) from among your free, Muslim men who are of good character. (And if two men be not (at hand) then a man and two women, of such as ye approve as witnesses) from among people who are reliable in their witness, (so that if the one erreth (through forgetfulness)) so that if one of the women forgets (the other) who did not forget (will remind her. And the witnesses must not refuse) to give witness (when they are summoned) to court. (Be not averse) disinclined (to writing down) i.e. the debt (whether it be small or great, with (record of) the term thereof. That) i.e. that which I mentioned regarding the writing down of the debt (is more equitable) more correct and fairer (in the sight of Allah and more sure for testimony) clearer for the witness when he gives his testimony if he happens to forget, (and the best way of avoiding doubt between you) concerning the debt and the fixed term of its payment; (save only in the case when it is actual merchandise which you transfer among yourselves from hand to hand.
