Believers, when you contract a debt for a fixed period, put it in writing. Let a scribe write it down between you with fairness; no scribe shall refuse to write as Allah has taught him. Therefore, let him write; and let the debtor dictate, fearing Allah his Lord, and do not decrease anything of it. If the debtor is a fool, or weak, or unable to dictate himself, let his guardian dictate for him in fairness. Call to witness two witnesses of your men, if the two are not men, then a man and two women from the witnesses whom you approve; so that if one of the two errs, one of them will remind the other. Whenever witnesses are called upon they must not refuse, and do not be weary to write it down, be it small or large, together with its term. This is more just with Allah; it ensures accuracy in testifying and is the least of doubt. Unless it is present merchandise that you circulate between you; then no guilt shall be on you if you do not write it down and take witnesses when you are selling, and let no harm be done to either scribe or witness. If you do, that is a transgression in you. Fear Allah. Allah teaches you, and Allah has knowledge of everything.
