How is the estate of a woman who died unmarried, but with children of three deceased siblings (one brother and two sisters) distributed, and what is the share of each of her heirs, who are: two sons and two daughters of her deceased brother, two daughters of her second deceased sister, and one daughter of her third deceased sister?

The children of the sister and the daughter of the brother are not among the heirs, so they have no share in the inheritance. The same applies to the children of the brother from the mother's side.

As for the sons of the full brother or the half-brother (from the father's side), they are among the heirs, and they receive all the wealth equally by ta'sib (agnatic inheritance) if there is no other heir.

Inheritance cases must be submitted to Sharia courts for verification and to search for wills, debts, and rights before dividing the inheritance.
