'A'isha, the wife of Allah's Apostle (ﷺ), reported Allah's Messenger (ﷺ) as having said this
Didn't you see that when your people built the Ka'ba, they reduced (its area with the result that it no longer remains) on the foundations (laid) by Ibrahim. I said: Messenger of Allah, why don't you rebuild it on the foundations (laid by) Ibrahim? Thereupon Allah's Messenger (ﷺ) said: Had your people not been new converts to Islam, I would have done that. 'Abdullah b. 'Umar (Allah be pleased with them) said: If 'A'isha (Allah be pleased with her) had heard it from Allah's Messenger (may peace be up (vn him), I would not have seen Allah's Messenger (ﷺ) abandoning the touching of the two corners situated near al-Hijr, but (for the fact) that it was not completed on the foundations (laid) by Ibrihim.
