أَخْبَرَنِي إِبْرَاهِيمُ بْنُ يَعْقُوبَ، قَالَ أَنْبَأَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ حُمَيْدِ بْنِ هِلاَلٍ، عَنْ سَعْدِ بْنِ هِشَامِ بْنِ عَامِرٍ، عَنْ أَبِيهِ، قَالَ : اشْتَدَّ الْجِرَاحُ يَوْمَ أُحُدٍ فَشُكِيَ ذَلِكَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ : " احْفِرُوا وَأَوْسِعُوا وَأَحْسِنُوا، وَادْفِنُوا فِي الْقَبْرِ الاِثْنَيْنِ وَالثَّلاَثَةَ، وَقَدِّمُوا أَكْثَرَهُمْ قُرْآنًا " .
It was narrated from Sa'd bin Hisham bin 'Amir that his father said: "Many people were wounded on the day of Uhud and complaints were made to the Messenger of Allah about that. He said: 'Dig graves and make them good and wide, and bury two or three in a grave, and put in first the one who knew the Qur'an most."' Translation Not Available
