Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Whoever helps an oppressor in his falsehood so that he erases the truth with his falsehood, then the protection of Allah and His Messenger is lifted from him. And whoever consumes one dirham of usury, it is equivalent to thirty-three (33) acts of adultery. And whoever's flesh is nourished by the unlawful, then the Fire is more deserving of him."
