Saeed bin Mina reported,

I heard Ibn Zubayr say from the pulpit, when he was about to demolish the Kaabah and rebuild it, "My aunt Ayesha told me that the Messenger of Allah ﷺ said to her, 'Ayesha, were it not that your people have only recently left polytheism, I would have demolished the Kaabah and brought it level with the ground, and I would have made for it two doors, an eastern door and a western door, and I would have added six cubits to it from the Hijr, for Quraysh fell short when they built the Kaabah.'"

Sahih

عن سعيد بن ميناء، قال

سمعت ابن الزبير يقول وهو على المنبر حين أراد أن يهدم الكعبة ويبنيها: حدثتني عائشة خالتي، أن رسول الله ﷺ قال لها: يا عائشة، لولا أن قومك حديثو عهد بشرك لهدمت الكعبة فألزقتها بالأرض، وجعلت لها بابين بابا شرقيا وبابا غربيا وزدت فيها ستة أذرع من الحجر فإن قريشا اقتصر تها حيث بنت الكعبة.
