The Old Testament stands as a backbone behind the New Testament. The Qu'ran is the interpretation of the Hebrew religion, and the Hebrew religion continued the message which was first given by Abraham. And therefore in these three religions there is the influence of this great master, of whom so little is known to the world. His initiation took place in the old school of Egypt; and when coming back from Egypt after his initiation he felt intuitively the place where his message was going to culminate, and was going to be a world message. In that place he put a stone, and that stone was called the Ka'ba. A stone which attracts thousands and millions of people for hundreds of years, where they go and offer their homage. A place which was visited with respect and reverence, with that sacred stone in view by the great prophet of Beni-Israel.
