4400. Narrated 'Abdullāh bin 'Umar رَضِيَ اللَّهُ عَنْهُمَا: The Prophet ﷺ arrived (at Makkah) in the year of the Conquest (of Makkah) while Usāma was riding behind him on (his she-camel) Al-Qaṣwā. Bilāl and 'Uthmān bin Ṭalḥa were accompanying him. When he made his she-camel kneel down near the Ka'bah, he said to 'Uthmān, "Get us the key (of the Ka'bah)." He brought the key to him and opened the gate (of the Ka'bah), for him. The Prophet ﷺ, Usāma, Bilāl and 'Uthmān (bin Ṭalḥa) entered the Ka'bah and then closed the gate behind them (from inside). The Prophet ﷺ stayed there for a long period and then came out. The people rushed to get in, but I went in before them and found Bilāl standing behind the gate, and I said to him, "Where did the Prophet ﷺ offer Ṣalāt (prayer)?" He said, "He offered Ṣalāt (prayer) between those two front pillars." The Ka'bah was built on six pillars, arranged in two rows, and he offered Ṣalāt (prayer) between the two pillars of the front row leaving the gate of the Ka'bah at his back and facing (in Ṣalāt) the wall which faces one when one enters the Ka'bah. Between him and that wall (was the distance of about three cubits). But I forgot to ask Bilāl about the number of Rak'ā, the Prophet ﷺ had prayed. There was a red piece of marble at the place where he (i.e., the Prophet ﷺ) had offered the Ṣalāt (prayer).
