Do the children of a brother who died before their sister inherit from her, given that she has sisters and a husband, and how is the inheritance divided in this case?

If your aunt's heirs are limited to her husband and her two sisters who died before her, then the inheritance is divided as follows: the husband receives one-half due to the absence of descendants for the deceased, and the two sisters receive two-thirds. As for the brother who died before her and his children, they do not inherit, because the heir's life was not stable after the deceased. Thus, the prescribed shares have exhausted the entire inheritance, and the inheritance is confined to the husband and the two sisters. It must be noted that matters of inheritance are serious and must be referred to the Sharia courts for investigation and to ensure there are no other heirs, wills, debts, or rights that take precedence over the rights of the heirs.
