Salim (the freed slave of Ibn Muti') heard Sayyiduna Abu Hurayrah (may Allah be pleased with him) say: When we conquered Khaybar, we did not obtain gold or silver as spoils; rather, we got camels, cattle, goods and orchards. Then we came with the Prophet (peace and blessings be upon him) to Wadi al-Qura, and with him (peace and blessings be upon him) was a slave called Mid'am, whom a man from Banu al-Dibab had gifted to him (peace and blessings be upon him). Once, while Mid'am was unloading the saddle from the mount of the Messenger of Allah (peace and blessings be upon him), suddenly a stray arrow from an unknown direction struck him and he died. The people said: Congratulations, this man is of the people of Paradise. The Messenger of Allah (peace and blessings be upon him) said: "No, by the One in whose hand is my soul! The cloak which he took from the spoils of Khaybar before the distribution is wrapped around him as fire." When the people heard this, a man brought one or two sandal straps to him (peace and blessings be upon him) and said: I had obtained these. He (peace and blessings be upon him) said: "These are one or two straps of fire."
