Sayyiduna Abdullah bin Umar (may Allah be pleased with them) narrated that the Messenger of Allah (peace and blessings be upon him) entered the Ka'bah, and Usamah bin Zaid, Bilal, and Uthman bin Talhah Hajabi were also with him. Then Uthman closed the door of the Ka'bah, and the Prophet stayed inside. When he came out, I asked Bilal, "What did the Prophet (peace and blessings be upon him) do inside?" He replied, "He left one pillar to his left, one to his right, and three behind him, and at that time there were six pillars in the Ka'bah. Then he performed prayer."
