Sayyiduna Hisham bin Amir (may Allah be pleased with him) said: On the day of Uhud the wounds became severe, and the Companions complained to the Messenger of Allah (peace and blessings be upon him) of the wounds. He (peace and blessings be upon him) said: "Dig the graves, make them wide and make them well, and bury two or three in one grave, and place in front the one who knew the most Qur'an." So my father was placed in front of two men.
