Islam, in the tenth century, was the main religion, or at least, the religion of the majority of nations in an area covering more than half of the civilized world stretching over three continents from the Pyrenees and Siberia in West and North Europe to the farthest end of Asia, up to China and New Guinea in the East; from Morocco in North Africa to the southern tip of Africa, covering two-thirds of the African continent.

It is one of the most striking facts of human history that the spread of Islam over such a vast area took place within three centuries. Most striking of all, within half a century after the Hijrah (Prophet Muhammad's Migration from Makkah to Al-Madeenah), Islam had already conquered the whole of North Africa from Egypt to Morocco, all the Middle Eastern lands from Yemen to Caucasia and from Egypt to the lands beyond Transoxiana (portion of Central Asia corresponding approximately with modern-day Uzbekistan and southwest Kazakhstan).

This has caused its missionaries and most of the orientalists to develop a complex within themselves by depicting Islam and introducing it as a regressive, vulgar religion of savage people.




Many have sought to answer the questions of why the triumph of Islam was so speedy and complete? Why have so many millions embraced the religion of Islam

A. J. Arberry has also pointed out that the reason for the spread of Islam is Islam itself and its religious values.

The rapidity of the spread of Islam, noticeably through extensive provinces which had been long Christian, is a crucial fact of history […] The sublime rhetoric of the Quran, that inimitable symphony, the very sounds of which move men to tears and ecstasy".
