It was narrated from ‘Amr bin Shuaib, from his father, from his father Muhammad bin ‘Abdullah bin ‘Amr — or on one occasion he said: from his father, from his grandfather — that on the Day of Khaibar, the Messenger of Allah صلی اللہ علیہ وآلہ وسلم forbade the flesh of domesticated donkeys and of Al Jallalah (animals that eat dung), and (he forbade) riding them and eating their meat.” (Hasan)
