The Women - 4:161 Because they practiced usury when they were forbidden to do so, and ate the people´s money unjustly... We prepared for their disbelievers a painful torment.
Usury:
The Cow/2:275 "Those who eat usurious money rise up like one who is struck by the devil. This is because they say, "Usury is like shopping". But Allah has made shopping lawful and usury unlawful. And whoever receives a reminder from his Lord and desists, he may keep what he has earned in the past, and his affair is up to Allah. As for those who continue, they are the inhabitants of Hell, and they will abide therein forever."
The Cow/2:276 Allah condemns usury and supports charity. Allah does not love any sinful ingrate.
The Cow/2:278 O you who believe, if you really believe, listen to Allah and abandon all forms of usury.
The Cow/2:279 If you do not do so, expect a war from Allah and His Messenger. If you repent, your principal is yours again. Do not be wronged nor be wronged.

The Romans/30:39 The usury money which you give to increase in the wealth of the people does not increase with Allah. But as for the zakat which you give seeking Allah´s Pleasure, those who give it multiply their investment.
