Sayyiduna Umayr, the freed slave of Abi al-Lahm (may Allah be pleased with him), said: I came to the Prophet (peace and blessings be upon him) on the day of Khaybar, and at that time I was a slave (owned by a master). I said: "Give me something too." So he (peace and blessings be upon him) gave me a sword and said: "Hang it on yourself." I took it and hung it on myself, but it fell to the ground. Then he (peace and blessings be upon him) gave me some odds and ends from the goods.
