Answer:
O Caliph
Step-by-step explanation:
The Caliph was the leader of the Caliphate, which was a political and religious system that emerged after the death of the Prophet Muhammad in the 7th century. The Caliph was considered to be the successor to Muhammad and was responsible for leading the Islamic community (umma) and enforcing Islamic law (sharia). The Caliph was not an emperor, president, or king, but rather a spiritual and political leader who held a unique position within the Islamic faith.
