It is narrated from Hazrat Ibn Umar (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) once entered the House of Allah (the Ka'bah), and at that time Hazrat Fadl bin Abbas (may Allah be pleased with him), Usama bin Zaid (may Allah be pleased with him), Uthman bin Talhah (may Allah be pleased with him), and Hazrat Bilal (may Allah be pleased with him) were with the Prophet (peace and blessings of Allah be upon him). At the command of the Prophet (peace and blessings of Allah be upon him), Hazrat Bilal (may Allah be pleased with him) closed the door, and they remained inside for as long as Allah willed. Then when the Prophet (peace and blessings of Allah be upon him) came out, the first person I met was Hazrat Bilal (may Allah be pleased with him), and I asked him where the Prophet (peace and blessings of Allah be upon him) had prayed. He told me, "Here, between these two pillars." However, I forgot to ask how many rak'ahs the Prophet (peace and blessings of Allah be upon him) had prayed.
