Those who consume usury shall not rise up (from their tomb) except as he who rises in madness that satan has touched. That is because they say: 'Selling is like usury' Allah has permitted trading and forbidden usury. To whomsoever an exhortation comes from his Lord then he desists, he shall have his past gains, and his matter is with Allah. But whoever reverts shall be among the people of the Fire and shall remain in it for ever.
