It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that on the day of the conquest of Makkah, the Messenger of Allah (peace and blessings be upon him) entered Makkah riding on the camel of Sayyiduna Usama bin Zaid (may Allah be pleased with him), and advanced until he made it sit in the courtyard of the Ka'bah. Then he called for Uthman bin Talhah to bring the key of the House of Allah. So he brought the key, and then the Prophet (peace and blessings be upon him) opened the door of the House of Allah and entered inside. Sayyiduna Usama (may Allah be pleased with him), Sayyiduna Bilal (may Allah be pleased with him), Sayyiduna Uthman bin Talhah (may Allah be pleased with him), (and according to one narration, Sayyiduna Fadl bin Abbas (may Allah be pleased with him)) entered the House of Allah with the Prophet (peace and blessings be upon him). They kept the door closed for quite some time. After that, when it was opened, I (Abdullah bin Umar) quickly moved ahead of the people and found Sayyiduna Bilal (may Allah be pleased with him) standing near the door. I asked him, "At which place did the Messenger of Allah (peace and blessings be upon him) perform the prayer?" He informed me that the Prophet (peace and blessings be upon him) performed the prayer between the two pillars in front, but I forgot to ask how many units (rak‘ahs) he had performed.
