Sunnis are the followers of the Sunni division of the Islamic religion. Sunnis belong to the larger of the two major divisions of Islam. The other major division is called Shiah, and its followers are called Shiites. Sunnis make up more than 80 percent of the Muslims (followers of Islam) in the world, and they live everywhere Islam has spread. This name comes from the Sunnis' claim that they follow the Sunna (example) of Muhammad, the prophet of Islam.
