Khilafah definition
Khilafah literally means a replacement, meaning the replacement of leadership after the Prophet Muhammad, not as a prophet, but as head of state. People who hold the position of caliph are called caliphs (Raharjo, t.t: 346). So the person who replaces the first caliph should be called the caliph of the first caliph, and who replaces the second caliph is called the caliph of the caliph who replaces the first caliph. Thus the word caliph will be used multiple times. However, this did not happen because the term caliph became a word that means "head of state" in Islam after the death of the Prophet Muhammad.
