THE MYTH OF MECCA
For an increasing number of Islamic historians, the tradition of Mohammed being the source and explanation of the Arab Conquest, wherein Arab tribesmen on horseback emerged out of the Arabian deserts to conquer Syria, Mesopotamia, Persia, Afghanistan, Egypt, Libya and Spain in less than 80 years (636-712), stands history on its head.
They demonstrate that the story of Mohammed uniting various Arab tribes as Genghiz Khan did for the Mongols, and providing them with the religious fervor to conquer in the name of Islam, is "sacred history," rather than real history.
