Those who swallow down usury cannot arise except as one whom Shaitan has prostrated by (his) touch does rise. That is because they say, trading is only like usury; and Allah has allowed trading and forbidden usury. To whomsoever then the admonition has come from his Lord, then he desists, he shall have what has already passed, and his affair is in the hands of Allah; and whoever returns (to it)-- these arc the inmates of the fire; they shall abide in it.

And when a party of them said: Why do you admonish a with a severe chastisement? They said: To be free from blame before your Lord, and that haply they may guard (against evil).

O men! there has come to you indeed an admonition from your Lord and a healing for what is in the breasts and a guidance and a mercy for the believers.

Call to the way of your Lord with wisdom and goodly exhortation, and have disputations with them in the best manner; surely your Lord best knows those who go astray from His path, and He knows best those who follow the right way.
