O you who believe! when you deal with each other in contracting a debt for a fixed time, then write it down; and let a scribe write it down between you with fairness; and the scribe should not refuse to write as Allah has taught him, so he should write; and let him who owes the debt dictate, and he should be careful of (his duty to) Allah, his Lord, and not diminish anything from it; but if he who owes the debt is unsound in understanding, or weak, or (if) he is not able to dictate himself, let his guardian dictate with fairness; and call in to witness from among your men two witnesses; but if there are not two men, then one man and two women from among those whom you choose to be witnesses, so that if one of the two errs, the second of the two may remind the other; and the witnesses should not refuse when they are summoned; and be not averse to writing it (whether it is) small or large, with the time of its falling due; this is more equitable in the sight of Allah and assures greater accuracy in testimony, and the nearest (way) that you may not entertain doubts (afterwards), except when it is ready merchandise which you give and take among yourselves from hand to hand, then there is no blame on you in not writing it down; and have witnesses when you barter with one another, and let no harm be done to the scribe or to the witness; and if you do (it) then surely it will be a transgression in you, and be careful of (your duty) to Allah, Allah teaches you, and Allah knows all things.

Say: O followers of the Book! come to an equitable proposition between us and you that we shall not serve any but Allah and (that) we shall not associate aught with Him, and (that) some of us shall not take others for lords besides Allah; but if they turn back, then say: Bear witness that we are Muslims.

And you are not (engaged) in any affair, nor do you recite concerning it any portion of the Quran, nor do you do any work but We are witnesses over you when you enter into it, and there does not lie concealed from your Lord the weight of an atom in the earth or in the heaven, nor any thing less than that nor greater, but it is in a clear book.

Is he then who has with him clear proof from his Lord, and a witness from Him recites it and before it (is) the Book of Musa, a guide and a mercy? These believe in it; and whoever of the (different) parties disbelieves in it, surely it is the truth from your Lord, but most men do not believe.

And those who disbelieve say: You are not a messenger. Say: Allah is sufficient as a witness between me and you and whoever has knowledge of the Book.

And on the day when We will raise up in every people a witness against them from among themselves, and bring you as a witness against these-- and We have revealed the Book to you explaining clearly everything, and a guidance and mercy and good news for those who submit.

And the earth shall beam with the light of its Lord, and the Book shall be laid down, and the prophets and the witnesses shall be brought up, and judgment shall be given between them with justice, and they shall not be dealt with unjustly.
