Muhammad bin 'Abdullah bin 'Abdul Hakam محمد بن عبد الله بن عبد الحكم · The Book of the Masjids

"The Messenger of Allah (ﷺ) entered the House (the Ka'bah), with Usamah bin Zaid, Bilal and 'Uthman bin Talhah, and they locked the door behind them. When the Messenger of Allah (ﷺ) opened it, I was the first one to enter. I met Bilal and asked him: 'Did the Messenger of Allah (ﷺ) pray inside?' He said: 'Yes, he prayed between the two Yemeni columns.'"
