Is it permissible to calculate the inheritance for a woman who passed away leaving behind two daughters, and another heir who is the daughter of her deceased brother, given that the mother had written a will before her death stipulating that the inheritance be divided among the three: the two daughters and the daughter of her deceased brother?

The deceased's will to divide her estate between her two daughters and her granddaughter (daughter of her son) is valid. The granddaughter receives one-third as a bequest, and the two daughters receive two-thirds of the remainder as a prescribed share. It is mentioned that two or more female children are entitled to two-thirds. Inheritance cases must be submitted to the Sharia courts due to their sensitive nature.
