عَنْ عُمَيْرٍ مَوْلَى آبِي اللَّحْمِ رَضِيَ اللَّهُ عَنْهُ قَالَ شَهِدْتُ خَيْبَرَ مَعَ سَادَتِي فَكَلَّمُوا فِيَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَأَمَرَ بِي فَقَلَّدْتُ سَيْفًا فَإِذَا أَنَا أَجُرُّهُ فَأُخْبِرَ أَنِّي مَمْلُوكٌ فَأَمَرَ لِي بِشَيْءٍ مِنْ خُرْثِيِّ الْمَتَاعِ
Mawla Abi al-Lahm Sayyiduna Umair (may Allah be pleased with him) narrates: He says, I was present with my masters in the Battle of Khaybar. When they spoke to the Messenger of Allah (peace and blessings be upon him) about me, he (peace and blessings be upon him) gave a ruling regarding me. I hung a sword with myself in such a way that it was dragging. When it was informed to the Prophet (peace and blessings be upon him) that I was a slave, he (peace and blessings be upon him) ordered that a small amount of household goods from the spoils of war be given to me.
