It is narrated from al-Qasim bin Muhammad (may Allah have mercy on him) that he said: I went to the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), and said: Dear mother! Uncover for me the graves of the Messenger of Allah (peace and blessings be upon him) and his two companions. So she showed (me) three low graves, covered with the red pebbles of the courtyard. The grave of the Messenger of Allah (peace and blessings be upon him) was in front; the head of Sayyiduna Abu Bakr (may Allah be pleased with him) was opposite the space between his (peace and blessings be upon him) two shoulders, and the head of Sayyiduna Umar (may Allah be pleased with him) was opposite his (peace and blessings be upon him) feet.
