(90) باب دَفْنِ الْجَمَاعَةِ فِي الْقَبْرِ الْوَاحِدِ
It was narrated that Hisham bin 'Amir said:
"On the day of Uhud the people were exhausted. The Prophet said: 'Dig graves and make them wide, and bury two or three in a grave.' They said: 'O Messenger of Allah, who should we 'put in first? He said: 'Put in first the one who knew the Qur'an most."'
