Al-Muttalib b. Abu Wada'a said that when ‘Uthman b. Maz'un died, was brought out on his bier and buried, the Prophet ordered a man to bring him a stone, but he was unable to carry it; so God’s messenger got up and, going over to it, rolled up his sleeves. Al-Muttalib remarked that the one who told him about God’s messenger said, “I still seem to see the whiteness of the forearms of God’s messenger when he rolled up his sleeves.” He then carried it and placed it at his head saying, “I am marking my brother’s grave with it, and I shall bury beside him those of my family who die.”
He said that the Prophet’s grave was sprinkled and that the one who sprinkled the water over his grave from a water-skin was Bilal b. Rabah. He began where the head was and sprinkled it to his feet.
Al-Qasim b. Muhammad told of his going to visit ‘A’isha and saying, “Mother, show me the grave of the Prophet and his two companions.” She showed him three graves which were neither high nor low, but were spread over with soft red pebbles in an open space.
