How is the inheritance legally divided in the event of the successive deaths of the father, the paternal uncle, and their mother, with heirs for each (males, females, and spouses), and a shared house? Do the paternal aunts inherit from their mother's estate? Do the grandchildren inherit from their grandmother?

First: Your father's inheritance is to be divided among his two sons, his wife, and his mother. The paternal uncle, his children, and the paternal aunts receive nothing. The mother gets one-sixth, the wife gets one-eighth, and the remainder goes to the two sons. Your paternal uncle's inheritance is to be divided among his children, his wife, and his mother. You and your paternal aunts receive nothing. The mother gets one-sixth, the wife gets one-eighth, and the remainder goes to the children (the male receives the equivalent of the share of two females). The grandmother has a share from your father's estate and your paternal uncle's estate (one-sixth from each), so her share of the house will be one-third.

Second: If the grandmother passes away, her estate goes to her heirs: her three daughters receive two-thirds, and the remainder goes to her son's daughters and their male siblings by 'asabah (agnatic relationship), where the male receives the equivalent of the share of two females.
