Where data is analyzed based on objectives and the formulation of the problem raised. The conclusion that can be drawn from this study according to the author is that the system of the government Khilafah is not a Shari'a but only a choice, which is the right system to be applied when a government system in its era is a system of kingdoms or sultanates. The Prophet himself never left a definite message on how the system of state administration, for example, how the state was formed, how was the system of appointment of heads of state, who had the right to set laws. Because of this ambiguity it can be seen that the practice of the Islamic state system in its history has always changed.
