Sunan an-Nasa'i 1955

Qutaybah narrated to us, saying: al-Layth narrated to us, from Ibn Shihab, from ‘Abd al-Rahman ibn Ka‘b ibn Malik, that Jabir ibn ‘Abd Allah informed him that the Messenger of Allah (peace and blessings of Allah be upon him) would place two of those killed at Uhud together in one garment, then ask: ‘Which of the two had learned more of the Qur’an?’ When one of them was indicated, he would place him first in the lahd (side-niche grave). He said: ‘I am a witness over these.’ He ordered that they be buried with their blood; he did not pray over them, and they were not washed.
