Hasan and Abdullah, both sons of Muhammad bin Ali, narrate from their father that Sayyiduna Ali (may Allah be pleased with him) said to Sayyiduna Ibn Abbas (may Allah be pleased with them both): You are a man who has gone astray; the Prophet (peace and blessings be upon him) "forbade mut'ah marriage and the meat of domestic donkeys at the time of Khaybar." Sufyan said that at the time of Khaybar the Prophet (peace and blessings be upon him) "forbade the meat of domestic donkeys", but not mut'ah marriage.
