It is narrated that Abu Hurayrah said: “A man gave as a gift to the Messenger of Allah صلى الله عليه وسلم a slave who was called Mid’am. Whilst Mid’am was bringing down a saddle for the Messenger of Allah صلى الله عليه وسلم, an arrow came out of nowhere and killed him. The people said, “How fortunate he is! Paradise is his,” but the Messenger of Allah صلى الله عليه وسلم said, “No, by the One in Whose hand is my soul, the cloak which he took from the war-booty on the day of Khaybar before the booty had been shared out will burn him with fire.” When the people heard that, a man came and brought one or two shoelaces to the Prophet صلى الله عليه وسلم and said, “A shoelace of fire” or “Two shoelaces of fire.”
