أَخْبَرَنَا مُحَمَّدُ بْنُ مَعْمَرٍ، قَالَ حَدَّثَنَا وَهْبُ بْنُ جَرِيرٍ، قَالَ حَدَّثَنَا أَبِي قَالَ، سَمِعْتُ حُمَيْدَ بْنَ هِلاَلٍ، عَنْ سَعْدِ بْنِ هِشَامِ بْنِ عَامِرٍ، عَنْ أَبِيهِ، قَالَ ‏:‏ لَمَّا كَانَ يَوْمُ أُحُدٍ أُصِيبَ مِنَ الْمُسْلِمِينَ، وَأَصَابَ النَّاسَ جِرَاحَاتٌ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏:‏ ‏
"‏ احْفِرُوا وَأَوْسِعُوا، وَادْفِنُوا الاِثْنَيْنِ وَالثَّلاَثَةَ فِي الْقَبْرِ، وَقَدِّمُوا أَكْثَرَهُمْ قُرْآنًا ‏"‏ ‏.‏
