Sayyidina Hisham ibn Aamir narrated : Someone complained to Allah’s Messenger about the wounds suffered in the Battle of Uhud. He said, “Dig the graves and make them wide and spacious, and clean them well. Bury two or three in one grave and place in front one who knew the Quran better (than the other).” My father had also died (a martyr) and was placed in the front of two men. [Abu Dawud 3215]
