حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ كَعْبِ بْنِ مَالِكٍ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ كَانَ يَجْمَعُ بَيْنَ الرَّجُلَيْنِ وَالثَّلاَثَةِ مِنْ قَتْلَى أُحُدٍ فِي ثَوْبٍ وَاحِدٍ ثُمَّ يَقُولُ ‏"‏ أَيُّهُمْ أَكْثَرُ أَخْذًا لِلْقُرْآنِ ‏"‏ ‏.‏ فَإِذَا أُشِيرَ لَهُ إِلَى أَحَدِهِمْ قَدَّمَهُ فِي اللَّحْدِ وَقَالَ ‏"‏ أَنَا شَهِيدٌ عَلَى هَؤُلاَءِ ‏"‏ ‏.‏ وَأَمَرَ بِدَفْنِهِمْ فِي دِمَائِهِمْ وَلَمْ يُصَلِّ عَلَيْهِمْ وَلَمْ يُغَسَّلُوا ‏.‏
