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 وسلمفَأَمَرَ 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, and they spoke to the Messenger of Allah, peace and blessings be upon him, concerning me. So he gave an order regarding me, and a sword was hung upon me, and I was dragging it. Then it was reported that I was a slave, so he ordered that I be given something from the miscellaneous goods.

Abu Dawud said: Its meaning is that he did not allot a share of the spoils to him.

Abu Dawud said: Abu 'Ubaid said: He had forbidden meat to himself, so he was named Abi al-Lahm.
