Mishkat al-Masabih 20 Game and Animals Which May Be Slaughtered كتاب الصيد والذبائح 61

وَعَنِ ابْنِ عُمَرَ قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ أَكْلِ الْجَلَّالَةِ وَأَلْبَانِهَا. رَوَاهُ التِّرْمِذِيُّ وَفِي رِوَايَةِ أَبِي دَاوُدَ: قَالَ: نُهِيَ عَنْ ركوبِ الْجَلالَة

Ibn ‘Umar told that God’s messenger prohibited eating the animal which feeds on filth or drinking its milk. Trimidhi transmitted it. In Abu Dawud’s version he said that he forbade riding the animal which feeds on filth.
