Legal and Judicial Study of Permeating the Verdict for the Inheritance Deprivation Due to Murder to the Deprivation of Legatee’s Inheriting from Testator

There is a consensus among Muslims that murderers are forbidden from inheritance. The main question of this research is that if the legatee murders the testator or the chamberlain, is it possible to extend the sentence of a forbidden murderer of inheritance to a will? Three hypotheses were put forward. Each one of the hypothesis was analyzed. The first case is if he commits murder with the intention of acquiring inheritance, and the second case is if he has no intention of acquiring inheritance. The second hypothesis is that the testator is an heir, and the same two states are assumed for the second hypothesis.
