Measurements for the Identification and Acquisition of Legitimate Expediency in the Islamic System

The present paper seeks to explain the extent of legitimacy in the temporary ignoring of the limits of Islamic rulings by the Muslim ruler. Knowing the important and more important criteria and the system of prioritizing government’s expediency can help the Islamic ruler to break the deadlock between social and material expediencies. Understanding the expediency and mechanisms of change in their changeable and unchangeable borders can be effective in enforcing Islamic legitimacy on a religious state. The limits for abrogating or developing the primary and secondary criteria in a religious government have a close relationship with the basic goals and intentions of the Shari'a. The main questions of this research pivot around the goals and frameworks of government, including whether the Islamic government is obliged to exercise divine limits, or can other purposes be assumed for them which cannot be ignored in case of the impossibility to implement divine limits. What are the mechanisms and tools of such a process? How far go the borders of ignoring the divine limits by the Muslim ruler? This research seeks to prove that prioritizing the objectives of the Islamic state, interpretation of expediency, the source and the basis of the analysis of expediency, the method, tool and methodology for the discovery and application of expediency, the factors of discovery and implementation of expediency are effective in the analysis of the degree of legitimacy and the functions of any political structure in Islam.
