Two men buried in one grave

Muhammad bin Ishaq narrates from his father, from the elders of the Ansar, that on the day of the Battle of Uhud the bodies of Sayyiduna Abdullah bin Amr bin Haram and Sayyiduna Amr bin al-Jamuh (may Allah be pleased with them both) were brought to the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) said: "Bury the two of them in a single grave, for indeed these two were true friends and companions in the world."

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

Al-Hasan said: Burying two persons (two bodies) in a single grave is disliked.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "See which of the two had memorized more of the Holy Qur'an, and place him first in the lahd."

Abd al-Rahman bin Ka'b bin Malik narrates from his father that the Prophet (peace and blessings be upon him) used to put two or three persons together in a single lahd (grave).
