Muhammad bin Hanafiyyah narrates: Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) said to Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both): The Prophet (peace and blessings be upon him) forbade temporary marriage (Nikah Mut'ah) and the eating of the meat of domesticated donkeys at the time of (the battle of) Khaybar. Sufyan says that by this narration it is meant that the Prophet (peace and blessings be upon him) forbade the eating of the meat of domesticated donkeys at the time of the battle of Khaybar. Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) did not mean that the Prophet (peace and blessings be upon him) also forbade temporary marriage at that time. (Rather, the prohibition of temporary marriage was given later.)
