What is the ruling of Islamic Sharia on dividing the mother's apartment after her death, especially with different accounts regarding her will concerning it? Should the apartment be divided as a legal inheritance, or given to the sister based on the uncle's narration of the mother's will, or does the sister receive half of the apartment based on "to the male, the equivalent of the share of two females" and the remaining half is divided among the heirs, while keeping the family apartment as a gathering place?

A father must be just among his children in gift-giving, such that he gives the male the share of two females. Otherwise, the gifts must be included in the inheritance and divided among all heirs. The apartment the father gave to the mother is part of the estate and will be divided among all heirs. If you give half of it to the sister and you all agree to that, there is no harm. Otherwise, she must be given half of what the male receives, and the remaining half will be divided among all heirs. There is no harm in keeping the family apartment jointly owned among you by agreement, provided that you respond to any future request for its division.
