Narrated 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 ﷺ 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 ﷺ said, "This is a strap, or these are two straps of Fire."

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا مُعَاوِيَةُ بْنُ عَمْرٍو، حَدَّثَنَا أَبُو إِسْحَاقَ، عَنْ مَالِكِ بْنِ أَنَسٍ، قَالَ حَدَّثَنِي ثَوْرٌ، قَالَ حَدَّثَنِي سَالِمٌ، مَوْلَى ابْنِ مُطِيعٍ أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ يَقُولُ افْتَتَحْنَا خَيْبَرَ، وَلَمْ نَغْنَمْ ذَهَبًا وَلاَ فِضَّةً، إِنَّمَا غَنِمْنَا الْبَقَرَ وَالإِبِلَ وَالْمَتَاعَ وَالْحَوَائِطَ، ثُمَّ انْصَرَفْنَا مَعَ رَسُولِ اللَّهِ ﷺ إِلَى وَادِي الْقُرَى، وَمَعَهُ عَبْدٌ لَهُ يُقَالُ لَهُ مِدْعَمٌ، أَهْدَاهُ لَهُ أَحَدُ بَنِي الضِّبَابِ، فَبَيْنَمَا هُوَ يَحُطُّ رَحْلَ رَسُولِ اللَّهِ ﷺ إِذْ جَاءَهُ سَهْمٌ عَائِرٌ حَتَّى أَصَابَ ذَلِكَ الْعَبْدَ، فَقَالَ النَّاسُ هَنِيئًا لَهُ الشَّهَادَةُ. فَقَالَ رَسُولُ اللَّهِ ﷺ " بَلَى وَالَّذِي نَفْسِي بِيَدِهِ، إِنَّ الشَّمْلَةَ الَّتِي أَصَابَهَا يَوْمَ خَيْبَرَ مِنَ الْمَغَانِمِ لَمْ تُصِبْهَا الْمَقَاسِمُ لَتَشْتَعِلُ عَلَيْهِ نَارًا ". فَجَاءَ رَجُلٌ حِينَ سَمِعَ ذَلِكَ مِنَ النَّبِيِّ ﷺ بِشِرَاكٍ أَوْ بِشِرَاكَيْنِ، فَقَالَ هَذَا شَىْءٌ كُنْتُ أَصَبْتُهُ. فَقَالَ رَسُولُ اللَّهِ ﷺ " شِرَاكٌ أَوْ شِرَاكَانِ مِنْ نَارٍ ".
