Musannaf Ibn Abi Shayba 28:1009

Muhammad ibn Fudayl narrated to us, from Muhammad ibn Ishaq, from Yazid ibn Khusayfa, from Salim, the freed slave of Ibn Muti’, from Abu Hurayrah, who said: Rifa’ah gifted a young slave to the Messenger of Allah (may Allah bless him and grant him peace). He went out with him to Khaybar, and he (the slave) dismounted between the afternoon (Asr) and sunset (Maghrib) prayers. A stray arrow came to the young slave and killed him. We said, "Congratulations to him for Paradise." He (the Prophet) said, "By the One in Whose hand is my soul, the cloak he took from the spoils of war before they were distributed is burning upon him now in the Fire." A man from the Ansar said, "O Messenger of Allah, I took two sandal straps on that day." He said, "Two like them of Hellfire will be presented to you."
