What did Prophet Muhammad (peace be upon him) say about the foundations of Ka`ba, if his people had not been close to the Pre-Islamic period of ignorance?
 Narrated `Aisha:                     Allah's Apostle said to me, "Were your people not close to the Pre-Islamic period of ignorance, I would have demolished the Ka`ba and would have rebuilt it on its original foundations laid by Abraham (for Quraish had curtailed its building), and I would have built a back door (too)."
