In the name of Allah, the Most Gracious, the Most Merciful
Al-Baqara
(2:275) Those who consume interest cannot stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity. That is because they say, “Trade is [just] like interest.” But Allah has permitted trade and has forbidden interest. So whoever has received an admonition from his Lord and desists may have what is past, and his affair rests with Allah . But whoever returns to [dealing in interest or usury] – those are the companions of the Fire; they will abide eternally therein.
(2:276) Allah destroys interest and gives increase for charities. And Allah does not like every sinning disbeliever.
(2:277) Indeed, those who believe and do righteous deeds and establish prayer and give zakah will have their reward with their Lord, and there will be no fear concerning them, nor will they grieve.
(2:278) O you who have believed, fear Allah and waive what is still due to you from usury if you are indeed believers.
(2:279) And if you do not, then be informed of a war [against you] from Allah and His Messenger. But if you repent, you may have your principal, causing no loss to debtor and suffering no loss.
(2:280) And if the debtor is in hardship, then [let there be] postponement until [a time of] ease to repay. But if you waive the sum by way of charity, then it is better for you, if you understand.
(2:281) And fear a Day when you will be returned to Allah. Then every soul will be compensated for what it earned, and they will not be treated unjustly.
(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.
(2:284) To Allah belongs whatever is in the heavens and whatever is in the earth. Whether you show what is within yourselves or conceal it, Allah will bring you to account for it. Then He will forgive whom He wills and punish whom He wills, and Allah is over all things competent.
(2:285) The Messenger has believed in what was revealed to him from his Lord, and [so have] the believers. All of them have believed in Allah and His angels and His books and His messengers, [saying], “We make no distinction between any of His messengers.” And they say, “We hear and we obey. [We seek] Your forgiveness, our Lord, and to You are the [final] destination.”
(2:286) Allah does not charge a soul except [with that within] its capacity. It will have [the consequence of] what [good] it has gained, and it will bear [the consequence of] what [evil] it has earned. “Our Lord, do not impose blame upon us if we have forgotten or erred. Our Lord, and lay not upon us a burden likes that which You laid upon those before us. Our Lord, and burden us not with that which we have no ability to bear. And pardon us; and forgive us; and have mercy upon us. You are our protector, so give us victory over the disbelieving people.”
Alay-Imran
(3:130) O you who have believed, do not consume usury, doubled and multiplied, but fear Allah that you may be successful.
(3:131) And fear the Fire, which has been prepared for the disbelievers.
(3:132) And obey Allah and the Messenger that you may obtain mercy.
(3:133) And hasten to forgiveness from your Lord and a garden as wide as the heavens and earth, prepared for the righteous
(3:134) Who spend [in the cause of Allah ] during ease and hardship and who restrain anger and who pardon the people – and Allah loves the doers of good;
(3:135) And those who, when they commit an immorality or wrong themselves [by transgression], remember Allah and seek forgiveness for their sins – and who can forgive sins except Allah ? – and [who] do not persist in what they have done while they know.
(3:136) Those – their reward is forgiveness from their Lord and gardens beneath which rivers flow [in Paradise], wherein they will abide eternally; and excellent is the reward of the [righteous] workers.
Ar-Rum
(30:38) So give the relative his right, as well as the needy and the traveler. That is best for those who desire the countenance of Allah, and it is they who will be the successful.
(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.
