Mukhtasar Bukhari (Abridged) 676 — Funeral prayer for a martyr

Narrated Jabir bin Abdullah (may Allah be pleased with him): The Prophet (peace and blessings of Allah be upon him) used to put two men from among the martyrs of Uhud in a single garment, then he would ask, "Which of them knew more of the Qur'an?" When one of them was pointed out, he would put him first in the grave and say: "I will be a witness for these people on the Day of Resurrection." And he (peace be upon him) ordered that they be buried with their blood, and they were neither washed nor was funeral prayer offered for them.
