Islam was founded in 610 CE on the Arabian Peninsula. It was founded by Muhammad and is a monotheistic religion.
The holy book of the Islamic religion is the Quran. The leader is Caliph and there are two subgroups, Sunnis and Shi'a. The Sunnis are successors of Muhammad, while the Shi'a believe any good Muslim can lead the community. Muslims believe in 5 Pillars; declaration of faith, daily prayer, alms for the poor, fast during Ramadan, and Hajj.
