It is narrated from Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Usury (riba) has seventy-two doors; the lowest of them is like a man committing adultery with his own mother, and the worst usury is a man's unjust attack with his tongue on the honour of his (Muslim) brother."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Yahya bin Abi Kathir (may Allah have mercy on him) except Umar bin Rashid (may Allah have mercy on him), and no one narrated it from Umar bin Rashid (may Allah have mercy on him) except Mu'awiyah bin Hisham (may Allah have mercy on him); and this report is not narrated from Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) except with this chain."
