Musannaf Ibn Abi Shaybah

Hazrat Abu Ishaq narrates from his father, and he from the elders of the Ansar, that on the day of the Battle of Uhud, the bodies of Hazrat Abdullah bin Amr (may Allah be pleased with him) bin Haram and Amr bin Jamuh were brought to the Holy Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said: Bury both of them in the same grave. Indeed, both of them were true friends and companions in the world.

It is narrated from Hazrat Jabir bin Abdullah (may Allah be pleased with him) that on the day of the Battle of Uhud, when two martyrs’ bodies were brought to the Holy Prophet (peace and blessings be upon him) to be buried in a single grave, he (peace and blessings be upon him) would ask: “Which of them had memorized more of the Qur’an?” When one of them was indicated, he (peace and blessings be upon him) would place him first in the grave.

Hasan says that burying two persons (bodies) in a single grave is disliked.

It is narrated from Hazrat Anas that the Holy Prophet (peace and blessings be upon him) said: See which of the two has memorized more of the Holy Qur'an, give him precedence in the grave.

Hazrat Abdur Rahman bin Ka'b bin Malik narrates from his father that the Holy Prophet (peace and blessings be upon him) would gather two or three persons in a single lahd (grave).
