Sunan An-Nasa'i
Hadith #2900
It was narrated from Aishah that the Messenger of Allah said:""Don't you see that when your people (re)built the Kabah, they did not build it on all the foundations laid by Ibrahim, peace be upon him?"" I said: ""O Messenger of Allah, why do you not rebuild it on the foundation of Ihrahim, peace be upon him?"" He said: ""Were it not for the fact that your people have recently left disbelief (I would have done so)."" Abdullah bin Umar said: ""Aishah heard this from the Messenger of Allah, for I see that he would not touch the two corners facing Al-Hijr because the House not built on the foundations of Ihrahim, peace be upon him?
