Someone came to Ibn ‘Umar in his house and said: “The Messenger of Allah ﷺ has entered the Ka’bah.” So Ibn ‘Umar said, I (Ibn ‘Umar) came and found that the Messenger of Allah ﷺ had come out, and I found Bilal (RA) standing at the door. I said: “ Bilal, did the Messenger of Allah ﷺ pray inside the Ka’bah?” He said: “Yes.” I said: “Where?” He said: “Between these two columns, two Rak’ahs. Then he came out and prayed two Rak’ahs in front of the Ka’bah.” (Sahih)
