`Aisha said that the Prophet (ﷺ) said to her, "O Aisha! Were your nation not close to the Pre-Islamic
Period of Ignorance, I would have had the Ka`ba demolished and would have included in it the portion
which had been left, and would have made it at a level with the ground and would have made two
doors for it, one towards the east and the other towards the west, and then by doing this it would have
been built on the foundations laid by Abraham." That was what urged Ibn-Az-Zubair to demolish the
Ka`ba. Jazz said, "I saw Ibn-Az-Zubair when he demolished and rebuilt the Ka`ba and included in it a
portion of Al-Hijr (the unroofed portion of Ka`ba which is at present in the form of a compound
towards the northwest of the Ka`ba). I saw the original foundations of Abraham which were of stones
resembling the humps of camels." So Jarir asked Yazid, "Where was the place of those stones?" Jazz
said, "I will just now show it to you." So Jarir accompanied Yazid and entered Al-Hijr, and Jazz
pointed to a place and said, "Here it is." Jarir said, "It appeared to me about six cubits from Al-Hijr or
so."
Sahih al-Bukhari Book 25, Hadith 72
"I came to the Messenger of Allah, who became Muslim with you?' He said: 'Free men and slaves.' I said: 'Is there any moment which brings one closer to Allah than another?' He said: 'Yes, the last part of the night, so pray as much as you want until you pray Subh, then stop until the sun has risen until and it looks like a shield and (its shinning)spreads. Then pray as much as you want until an object's shadow is at its shortest, then stop until the sun passes its zenith, for Hell is stoked at midday. Then pray 'Asr, then stop until you pray 'Asr, then stop until the sun has set, for it sets between the horns of a Shaitan and rises between the horns of a Shaitan.'"
Similar has been recorded by Muslim.
