2. Sura Al-Báqara

Allāh destroys interest and gives increase for charities. And Allāh does not like every sinning disbeliever.

Indeed, those who believe and do righteous deeds and establish prayer and give zakāh will have their reward with their Lord, and there will be no fear concerning them, nor will they grieve.

O you who have believed, fear Allāh and give up what remains [due to you] of interest, if you should be believers.

And if you do not, then be informed of a war [against you] from Allāh and His Messenger. But if you repent, you may have your principal - [thus] you do no wrong, nor are you wronged.

And if someone is in hardship, then [let there be] postponement until [a time of] ease. But if you give [from your right as] charity, then it is better for you, if you only knew.

And fear a Day when you will be returned to Allāh. Then every soul will be compensated for what it earned, and they will not be wronged [i.e., treated unjustly].

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 Allāh has taught him. So let him write and let the one who has the obligation [i.e., the debtor] dictate. And let him fear Allāh, 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 them [i.e., 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 Allāh 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 Allāh. And Allāh teaches you. And Allāh is Knowing of all things.

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 Allāh, his Lord. And do not conceal testimony, for whoever conceals it - his heart is indeed sinful, and Allāh is Knowing of what you do.

To Allāh belongs whatever is in the heavens and whatever is in the earth. Whether you show what is within yourselves or conceal it, Allāh will bring you to account for it. Then He will forgive whom He wills and punish whom He wills, and Allāh is over all things competent.
