Abdullah bin Umar reported,

On the day of the Conquest, the Messenger of Allah ﷺ entered Makkah riding a she-camel belonging to Usama bin Zayd. He made it kneel near the Kaabah, then called for Uthman bin Talha to bring the key.Uthman went to fetch it, but his mother refused to hand it over.He said to her, "You will give it to me, or else a sword will come forth from my back."So she gave it to him, and he handed it to the Prophet ﷺ, who opened the door and entered along with Bilal, Uthman, and Usama. They closed the door behind them and remained inside for a long while.Ibn Umar said, "I was a strong young man at the time, so I rushed ahead of the people and reached the door before them. I found Bilal standing at the entrance.I asked him, "Where did the Messenger of Allah ﷺ pray?"He replied, "Between the two front pillars."But I forgot to ask him how many units of prayer he performed.

عن ابن عمر

دخل رسول الله ﷺ يوم الفتح وهو على ناقة لأسامة بن زيد فأناخ يعني بالكعبة ثم دعا عثمان بن طلحة بالمفتاح فذهب يأتيه به فأبت أمه أن تعطيه فقال لتعطينه أو يخرج بالسيف من صلبي فدفعته إليه ففتح الباب فدخل ومعه بلال وعثمان وأسامة فأجافوا الباب عليهم مليا قال ابن عمر وكنت رجلا شابا قويا فبادرت الناس فبدرتهم فوجدت بلالا قائما على الباب فقلت أين صلى رسول الله ﷺ فقال بين العمودين المقدمين ونسيت أن أسأله كم صلى
