Yahya related to me from Malik from Thawr ibn Zayd ad-Dili fromAbu'l-Ghayth Salim, the mawla of ibn Muti that Abu Hurayra said, "Wewent out with the Messenger of Allah, may Allah bless him and granthim peace, in the yearof Khaybar. We did not capture any gold orsilver except for personal effects, clothes, and baggage. Rifaa ibnZayd presented a black slave boy to the Messenger of Allah, may Allahbless him and grant him peace, whose name was Midam. The Messenger ofAllah, may Allah bless him and grant him peace, made for Wadi'l-Qura,and when he arrived there, Midam was unsaddling the camel of theMessenger of Allah, may Allah bless him and grant him peace, when astray arrow struck and killed him. The people said, 'Good luck to him!The Garden!' The Messenger of Allah said, 'No! By He in whose hand myself is! The cloak which he took from the spoils on the Day of Khaybarbefore they were distributed will blaze with fire on him.' When thepeople heard that, a man brought a sandal-strap or two sandal-strapsto the Messenger of Allah, may Allah bless him and grant him peace.The Messenger of Allah, may Allah bless him and grant him peace, said,'A sandal-strap or two sandal-straps of fire!' "
