Quran 2:274 — The Heifer (Al-Baqarah)

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.

[2:273] Charity shall go to the poor who are suffering in the cause of GOD, and cannot emigrate. The unaware may think that they are rich, due to their dignity. But you can recognize them by certain signs; they never beg from the people persistently. Whatever charity you give, GOD is fully aware thereof.

[2:275] 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.
