c. Caliph
Caliph is the title given to a Muslim authority who is known to be the
successor of the prophet. It was told that when Prophet Muhammad died, it was
Abu Bakr who followed his steps taking over the political and administrative
duties and responsibilities. The term was also used in Q’ran to refer to Adam
and David as vice-regents of God. Abu
Bakr together with his successors are considered to be the perfect caliphs or
successors in their times.
