It was narrated from Jabir bin ‘Abdullah that the Messenger of Allah (ﷺ) used to put two or three of the slain of Uhud in one shroud. He would ask:
“Which of them had memorized more Qur’an?” And if one of them was pointed out to him, he would put him in the niche-grave first. And he said: “I am a witness over them.” He commanded that they should be buried with their blood, and that the funeral prayer should not be offered for them and they should not be washed.
