"Submission to God's will" is the meaning of the word "Islam." Muslims are those who follow Islam. Muslims are monotheists who believe in a single, all-knowing God, known in Arabic as Allah.
The three groups within Islam are:
1. Sunni Muslims follow Muhammad's lead.
2. Shias believe that the leader should be Muhammad's descendant.
3. Sufis live in poverty and devote their lives to a spiritual path.
• Despite the fact that three main sects of Islam, Sunni, Shia, and Sufi agree on most of the essential principles and practices of Islam, there has been a deep schism between them for over 14 centuries.
• The schism began with a disagreement about who should succeed Prophet Muhammad as head of the Islamic faith he founded.
