The history of Abraham dates back four thousand years. During the period in which he lived polytheism was prevalent throughout the known and inhabited world, and had thus come to be a permanent feature of life, continuing from one generation to the next, without any break. Ultimately, the stage was reached when no new born child could learn anything other than polytheism from its surroundings. Abraham was born in Iraq. God commanded him to leave the populated areas of Iraq, Syria and Egypt and go to the uninhabited area of Hijaz and settle his progeny in Arabia. The idea behind settling in a desert area was that here, in an isolated place, a new generation could be brought up, cut off from the influence of polytheism prevalent in the inhabited world of the time. In accordance with this plan of God, Abraham settled his progeny in a place known at present as Makkah, but which was totally unpopulated in those days. At that time, Abraham built a mosque (the Kabah) which was to be the centre of worship for the one God by the new generation, and finally by the whole world.
