A Study of the Historical Formation of New Corollaries in Shiite Advanced Jurisprudence

With the addition of new corollaries to Shiite jurisprudence during the era of al-Tafri' jurisprudence (the jurisprudence that has the two following features: 1. the inference of issues and subjects in principles. 2. The systematic provision of jurisprudential texts based on Ijtihad and without depending on the text of the principle), new principles were added along with new corollaries to the structure of jurisprudence. Although the origin of some of them can be analyzed historically, but an important part of the consequences in this process has been unknown thus far. One of these cases is the phenomenon in which a variable in one period is added to the topics of an issue and while addressing the issue immediately affects all the branches. Then, over time, it becomes one of the principles to inference the other branches. This study tries to investigate these developments and criteria and illustrate its effects and consequences in Shiite jurisprudence through analyzing the evolution course of jurisprudential branches, from formation to evolution. The study is conducted based on the issue, "the definition of the criteria and limits of obedience in alimony". This issue has been involved in complexities and conflicts over different periods by passing a series of developments. By carrying out this study, the role of the historical course of the companion's approach to the formation of complexities and ambiguities in this branch will be clarified.
