Pilgrims circulating around the Kaaba in Mecca

Ahmed Mater: Magnetism

"It all began in the mists of time with Adam's expulsion from the Garden of Eden. He it was, the first man to have immediate contact with God, who built the first Ka'ba, the great cubic block that is the most important physical feature of the Hajj in Mecca; this, by the time of Abraham, some 1,700 years BC, had so deteriorated that its site had to be revealed to him by God Himself. By divine design, no doubt, it was close to the place where Abraham had abandoned Hagar, the Egyptian slave who had borne him his then only son, Ishmael...
As Abraham returned to Mecca and, with young Ishmael's aid, rebuilt the Ka'ba, he is regarded as the founder of the Hajj and its first pilgrim. During the rebuilding a mysterious Black Stone, a metre or so long, was set in the wall; this, profoundly precious to Islam, is variously believed to have been discovered by Ishmael on a nearby hill, or to have been given to Abraham by the Archangel Gabriel."
