from his father, form his grandfather - the on the Day of Kahaibar, the Messenger of Allah forbade the flesh of domesticated donkeys and of al-Jallalah (animals that eat dung), and (he forbade) riding them and eating their mat."

أَخْبَرَنِي عُثْمَانُ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنِي سَهْلُ بْنُ بَكَّارٍ، قَالَ حَدَّثَنَا وُهَيْبُ بْنُ خَالِدٍ، عَنِ ابْنِ طَاوُسٍ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، مُحَمَّدِ بْنِ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ مَرَّةً عَنْ أَبِيهِ، وَقَالَ، مَرَّةً عَنْ جَدِّهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى يَوْمَ خَيْبَرَ عَنْ لُحُومِ الْحُمُرِ الأَهْلِيَّةِ وَعَنِ الْجَلاَّلَةِ وَعَنْ رُكُوبِهَا وَعَنْ أَكْلِ لَحْمِهَا ‏.‏
