It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) entered the Sacred House (the Ka'bah) with Sayyiduna Usamah, Bilal, and Uthman bin Talhah Hajabi (may Allah be pleased with them), and the door was closed from inside. When the door was opened, I was the first to enter. I met Sayyiduna Bilal (may Allah be pleased with him) and asked him, "Did the Prophet (peace and blessings be upon him) pray inside the Ka'bah?" He said, "Yes! Between the two pillars on the right-hand side."
