Business transaction

In the name of Allah, the most Gracious, the most Merciful

(2:188) And do not consume one another’s wealth unjustly or send it [in bribery] to the rulers in order that [they might aid] you [to] consume a portion of the wealth of the people in sin, while you know [it is unlawful].

(2:282) 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 Allah has taught him. So let him write and let the one who has the obligation dictate. And let him fear Allah, 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 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 Allah 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 Allah . And Allah teaches you. And Allah is Knowing of all things.
(2:283) And if you are on a journey and cannot find a scribe, then a security deposit [should be] taken. And if one of you entrusts another, then let him who is entrusted discharge his trust [faithfully] and let him fear Allah, his Lord. And do not conceal testimony, for whoever conceals it – his heart is indeed sinful, and Allah is Knowing of what you do.

(4:29) O you who have believed, do not consume one another’s wealth unjustly but only [in lawful] business by mutual consent. And do not kill yourselves [for one another]. Indeed, Allah is to you ever Merciful.
(4:30) And whoever does that in aggression and injustice – then We will drive him into a Fire. And that, for Allah, is [always] easy.
(4:31) If you avoid the major sins which you are forbidden, We will remove from you your lesser sins and admit you to a noble entrance [into Paradise].

(5:1) O those who believed! Fulfill your contract obligations. …

(6:152) Not to go near the property of an orphan except in the best way [to improve it], until he attains maturity.  Give full measure and just weight – We never charge a soul with more than it can bear.  Whenever you speak, be just, even if it affects your own relatives, and fulfill your covenant with Allah.  These are the things which He has enjoined on you so that you may guard yourselves against evil.

(17:35) And give full measure when you measure, and weigh with an even balance. That is the best [way] and best in result.

(30:39) And whatever you give for interest to increase within the wealth of people will not increase with Allah. But what you give in zakah, desiring the countenance of Allah – those are the multipliers.

(83:1) Woe to those who defraud,
(83:2) who when, they take by measure from men, take the full measure,
(83:3) but when they give by measure or by weight to others, they give less than due.
(83:4) Do they not think that they will be raised to life again
(83:5) on a Mighty Day,
(83:6) a Day when all mankind will stand before the Rabb of the worlds?
