Umayr (may Allah be pleased with him), the slave of Abu al-Lahm, related: I was present at Khaybar while I was a slave. I said: O Messenger of Allah (peace and blessings be upon him)! Give me a share as well. So he (peace and blessings be upon him) gave me a sword. He (peace and blessings be upon him) said: "Hang this sword on yourself," and he (peace and blessings be upon him) gave me some odds and ends of goods, but he did not give me a share.
Muslim recorded another hadith on zakah with this chain, and this text too is sahih (authentic) on his condition.
