''Allah's Apostle, Usama bin Zaid, Bilal, and Uthman bin abu Talha entered the Ka'ba and then closed its door. When they opened the door I was the first person to enter (the Ka'ba). I met Bilal and asked him, ''Did Allah's Apostle offer a prayer inside (the Ka'ba)?'' Bilal replied in the affirmative and said, ''(The Prophet offered the prayer) in between the two right pillars.''
