Jurisprudential Feasibility of Generalizing the Sentence of Disinheritance Due to Murder by Wills, Assisting in Murder, and Murder of Excluder from the Point of View of Islam's Two Main Sects, Sunni and Shi'a

Sometimes it is possible that due to some reasons, the heir is prevented from inheriting from the heirs which these are called the obstacles to inheritance. Now, this research seeks to find an answer to this basic question: can the judgment of a murderer who killed his testator and is deprived of inheritance be extended to other similar jurisprudential chapters, such as will? Or if someone kills his excluder to get inheritance or assists in the murder to get inheritance, is he also deprived of inheritance? This article aims at providing a reasoned answer to the above question. To answer this question, using library sources and descriptive-analytical methods, different modes have been considered for the research problem; in the case where the legatee is an heir or not. Assisting in murder and the murder of excluder were also investigated. The opinions of Shi'a and Sunni jurists were examined. Then, by analyzing the opinions and findings of the research, it can be concluded that it is possible to generalize the verdict to other chapters such as the will and the murder of excluder. The reason for its feasibility can be considered as the application of hadiths, the possessing property unlawfully, as well as the abolition of character, custom, Conduct of the Wise, and legislator’s taste. The confirmatory proof for executing the custom of the wise is the application of deprivation in American laws.
