(87) باب مَا يُسْتَحَبُّ مِنْ تَوْسِيعِ الْقَبْرِ
It was narrated from Sa'eed bin Hisham bin 'Amir that his father said:
"On the day of Uhud some of the people among the Muslims were killed, and people were wounded. The Messenger of Allah said: 'Dig graves and make them wide, and bury two or three in a grave, and put the one who knew more Qur'an in first."'
