حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا بِشْرٌ، - يَعْنِي ابْنَ الْمُفَضَّلِ - عَنْ مُحَمَّدِ بْنِ زَيْدٍ، قَالَ حَدَّثَنِي عُمَيْرٌ، مَوْلَى آبِي اللَّحْمِ قَالَ شَهِدْتُ خَيْبَرَ مَعَ سَادَتِي فَكَلَّمُوا فِيَّ رَسُولَ اللَّهِ صلى الله عليه وسلم فَأَمَرَ بِي فَقُلِّدْتُ سَيْفًا فَإِذَا أَنَا أَجُرُّهُ فَأُخْبِرَ أَنِّي مَمْلُوكٌ فَأَمَرَ لِي بِشَىْءٍ مِنْ خُرْثِيِّ الْمَتَاعِ . قَالَ أَبُو دَاوُدَ مَعْنَاهُ أَنَّهُ لَمْ يُسْهِمْ لَهُ . قَالَ أَبُو دَاوُدَ وَقَالَ أَبُو عُبَيْدٍ كَانَ حَرَّمَ اللَّحْمَ عَلَى نَفْسِهِ فَسُمِّيَ آبِي اللَّحْمِ .
Narrated Umayr, client of AbulLahm: I was present at Khaybar along with my masters who spoke about me to the Messenger of Allah (ﷺ). He ordered about me, and a sword was girded on me and I was trailing it. He was then informed that I was a slave. He, therefore, ordered that I should be given some inferior goods. Abu Dawud said: This means that he (the Prophet) did not allot a portion of the spoils. Abu Dawud said: Abu 'Ubaid said: As he (the narrator Abi al-Lahm) made eating meat unlawful on himself, he was called Abi al-Lahm (one who hates meat)
