How is the inheritance of an endowed house (waqf) that was rented to a grandfather with six sons and three daughters distributed, and does it differ from a normal inheritance, especially with a written will stating that the male's share is double that of the female, and should the Sharia, which stipulates the equal distribution of endowments, be followed, or the will?

If a man dedicates an endowment (waqf) to his children without specifying proportions, then male and female beneficiaries are equal in benefiting from it. This is by agreement among the jurists. However, if the endower stipulates a specific division, such as requiring the male to receive the share of two females, then his condition is valid and must be observed. Some scholars have even recommended this type of division.
