Musannaf Ibn Abi Shaybah

Hazrat Saeed bin Hisham narrates from his father that on the day of Uhud, when the large number of those killed was mentioned to the Noble Prophet (peace and blessings be upon him), he said: "Dig graves, make them wide and good. And bury two or three people in one grave. Give precedence among the dead to the one who knows more Qur'an." So the people gave precedence to my father over two men.
