Answer:
passing of power
Step-by-step explanation:
Although Islam is the dominant religion, serious divisions exist between its observers. Early in Islam's history, a major split occurred between the Shiite and the Sunni Muslims over political power. One group, the Shiites, believed that power should be passed on within Muhammad's (the founder of Islam) own family. The Sunnis, on the other hand, felt that power should be passed down through the lines of the clergy.
