Investigating the Shiite theological approach to the place of expediency in deducing religious rules

One of the basic principles in the inference of religious rules in Shia jurisprudence is the principle of expediency. The justification of expediency as the source of the inference of religious law is based on the verbal foundations of this principle. This paper examines the place of interest in ijtihad and the inference of religious judgments with the Shiite theological approach. This research is a descriptive-adaptive research that has been conducted in a librarian way based on the analysis of documents of Shiite theological and jurisprudential sources on the basis of the principle of expediency. Theological foundations of expediency in the system of the Shi'a from the Shia point of view include the elements of perfection and prosperity, divine knowledge, divine justice, divine wisdom, rationality and goodness. The element of expediency is not merely considered in the system of the Transcendental God and in the process of the codification of the heavenly laws, the process of governing the Islamic ruler in the age of presence and absence is also in the circle of this discussion, precisely for this reason, its importance becomes twofold. In the study of the Shi'i theological approach it is expedient to conclude that the adherence to the rules of the material and the corruptions of al-Amri is one of the results of the famous theological statement in the Shiite language, which states: God's transcendental actions are purposeful and superstitious (unwittingly, unpardonable) It is impossible.
