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.

They ask you for a decision of the law. Say: Allah gives you a decision concerning the person who has neither parents nor offspring; if a man dies (and) he has no son and he has a sister, she shall have half of what he leaves, and he shall be her heir she has no son; but if there be two (sisters), they shall have two-thirds of what he leaves; and if there are brethren, men and women, then the male shall have the like of the portion of two females; Allah makes clear to you, lest you err; and Allah knows all things.

And a believing man of Firon's people who hid his faith said: What! will you slay a man because he says: My Lord is Allah, and indeed he has brought to you clear arguments from your Lord? And if he be a liar, on him will be his lie, and if he be truthful, there will befall you some of that which he threatens you (with); surely Allah does not guide him who is extravagant, a liar:

O Prophet! when believing women come to you giving you a pledge that they will not associate aught with Allah, and will not steal, and will not commit fornication, and will not kill their children, and will not bring a calumny which they have forged of themselves, and will not disobey you in what is good, accept their pledge, and ask forgiveness for them from Allah; surely Allah is Forgiving, Merciful.
