It is narrated from Sayyida Aisha (may Allah be pleased with her), she says: O Messenger of Allah! All your wives have entered the House of Allah (Ka'bah) except me (and I have not entered). The Prophet (peace and blessings be upon him) said: Send a message to Shaybah that he should open the door for you. So she sent the message, but Shaybah said: Neither in the time of ignorance did we have the authority, nor do we have it now in Islam, to open it at night. The Prophet (peace and blessings be upon him) said: Aisha! Then perform prayer in the Hijr, because when your people built the House of Allah, due to lack of funds, they made it smaller. In another narration: Perform prayer in the Hijr, for it is also a part of the House of Allah.
