Sayyiduna Umayr, the freed slave of Abi al-Lahm (may Allah be pleased with him), said: I took part in the campaign of Khaybar with my master and was present at its conquest. I asked the Prophet (peace and blessings be upon him) to give me a share too (of the spoils), and he (peace and blessings be upon him) gave me some minor items from the goods but did not give me a formal share.
