“5. The center of focus of the Kabah that Muslims circle 7 times counterclockwise once a year during the Hajj, is a meteorite called the black stone. This meteorite is the reference point by which they count the 7 revolutions (tawaf). It is the “zero” marker.
This shows the true origin of the Hajj to be pagan. Obviously a real meteorite fell sometime before Muhammad was born and the pagan Arabs began worshipping it. A similar pagan worship of a meteorite is found in Ephesus when Apostle Paul visited it: Acts 19:34-36″
