Aishah narrated: "I wanted to enter the House to perform Salat in it, so the Messenger of Allah (ﷺ) took me by the hand and put me in the Hijr, and he said: 'Perform Salat in the Hijri if you want to enter the House. For indeed it is part of the House, but your people considered it insignificant when they built the Ka'bah, so they put it outside the House.'"
