Quran 2:275 — The Heifer (Al-Baqarah)

Those who charge usury are in the same position as those controlled by the devil's influence. This is because they claim that usury is the same as commerce. However, GOD permits commerce, and prohibits usury. Thus, whoever heeds this commandment from his Lord, and refrains from usury, he may keep his past earnings, and his judgment rests with GOD. As for those who persist in usury, they incur Hell, wherein they abide forever.

[2:274] Those who give to charity night and day, secretly and publicly, receive their recompense from their Lord; they will have nothing to fear, nor will they grieve.

[2:276] GOD condemns usury, and blesses charities. GOD dislikes every disbeliever, guilty.
