Sahih Bukhari | Volume 5 | Hadith Number 541
Narrated by Abu Huraira
When we conquered Khaibar, we gained neither gold nor silver as booty, but we gained cows, camels, goods and gardens. Then we departed with Allah's Apostle to the valley of Al-Qira, and at that time Allah's Apostle had a slave called Mid'am who had been presented to him by one of Banu Ad-Dibbab. While the slave was dismounting the saddle of Allah's Apostle an arrow the thrower of which was unknown, came and hit him. The people said, "Congratulations to him for the martyrdom." Allah's Apostle said, "No, by Him in Whose Hand my soul is, the sheet (of cloth) which he had taken (illegally) on the day of Khaibar from the booty before the distribution of the booty, has become a flame of Fire burning him." On hearing that, a man brought one or two leather straps of shoes to the Prophet and said, "These are things I took (illegally)." On that Allah's Apostle said, "This is a strap, or these are two straps of Fire."
