Islam spread for many reasons. First, Islam had a religious zeal and a belief in jihad (Holy war or struggle against temptation) so many people fought for their beliefs. Second, the Arabian Peninsula was overpopulated causing people to move and therefore spreading their religion. Third, there was also a desire for new lands and wealth, once again spreading the religion.
