Can someone explain why is there is no reference in the Holy Writings of the Bible  of Ishmael rebuilding the Kaaba and that he received the black stone from the angel Gabriel as Islam’s tradition has it, nor to Abraham’s being in ancient Mecca? —Genesis 12:8–13:18.

In fact where in God’s Word will you find the word Mecca during the time of Abraham, Ishmael and Ishmael’s 12 chieftains? Why didn’t they speak of such a historic moment as well as a prophet Muhammad?

For such an important event surly the Word of God would have mentioned it or showed that it had his backing and approval, at least prophesy about it. It was showed at Mount Sinai that Moses had God’s backing. It was showed that Jesus and his 12 Apostles had God’s backing.

What manifestations did the Muhammad show that he had God’s backing? Whether people believed or not it was still shown to them.
