Narrated Aishah, Ummul Muminin: I liked to enter the House (the Kabah) and pray therein. The Messenger of Allah ﷺ caught me by hand and admitted me to al-Hijr. He then said: Pray in al-Hijr when you intend to enter the House (the Kabah), for it is a part of the House (the Kabah). Your people shortened it when they built the Kabah, and they took it out of the House.
