Sahih Muslim , Book 15, Hadith 435 (In-Book) ⓘ

Ibn Umar (Allah be pleased with them) reported: Allah's Messenger came on the Day of Victory, and got down in the courtyard of the Ka'ba and he sent (a message) for 'Uthman b. Talha (Allah be pleased with them). He came with the key and opened the door. Allah's Apostle then entered therein and Bilal, Usama b. Zaid, and 'Uthman b. Talha (along with him), and then commanded the door to be closed. They stayed there for a considerable time, and then the door was opened, and Abdullah said: I was the first to meet Allah's Messenger.. outside (the Ka'ba), and Bilal was close behind him. I said to Bilal: Did Allah's Messenger observe prayer therein? He said: Yes. I said: Where? He said: Between the two pillars in front of his face. He said: I forgot to ask him as to the number of rakahs he prayed.
