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 make yourself submissively gentle to them with compassion, and say: O my Lord! have compassion on them, as they brought me up (when I was) little.

And they disobeyed the Messenger of their Lord, so He punished them with a vehement punishment.
