The Criteria to Discover Importance to Find the Superior Preference from the Perspective of Usul Fiqh (the Principles of the Jurisprudence) Based on the Ideas of Main Islamic Sects

Objective examples of two conflicting verdicts are abundant in many subjects, and the examination of criteria to find the superior preferences reveals that it has not been accurately analyzed. With a brief look at the issues of the principles of jurisprudence, it appears that some issues such as: conflict and preference have been discussed in a scattered manner. The axial issue in this article is the position of the most important subjects of Usul Fiqh to find the preference and importance based on Islamic sects and their Usul Fiqh studies . The author's idea is to re-examine the content of the theories, not just to find common titles. Because of the lack of similarity between the title of Tazahum (emulation in acting) in relation to the two schools of Imamiyyah and Sunni and their Usul Fiqh, it is necessary to study principled-jurisprudential content of the materials that are likely related to this article's title . With this approach, the criteria do not result in scientific conclusions merely, but help to explain the practical aspect of these titles, and also because of these evaluations, the verbal and semantic commonalities have been explained based on main Islamic sects ideas in the subject of Usul Fiqh. Therefore, in this article, the researcher has chosen a descriptive-analytical method. Research findings show that In the "Principles of Jurisprudence", based on the ideas of Islamic sects, such rules like "avoiding the corruption is more important than gaining the benefits ", the similarity between the verdict and the subject, and the purposes of religion have a special role in the discovery of importance and preferences. There are also two important origins in the discussion of Tazahum (emulation in acting) in the Ahl al-Sunnah principles, namely: The jurisprudence of the preferences and the jurisprudence of the balanced matter were studied. Although there are more differences in terms of titles, but in terms of content and concepts, there are many similarities.
