Yahya related to me from Malik from Ibn Shihab from Abdullah and
Hasan, the sons of Muhammad ibn Ali ibn Abi Talib from their ather,
mayAllah be pleased with him, that the Messenger of Allah, may Allah
bless him and grant him peace, forbade temporary marriage with women
and the flesh of domestic donkeys on the Day of Khaybar.
Muwatta Malik Book 28, Hadith 45
