Do the children of a deceased daughter inherit from their deceased mother if their father is not the owner of the apartment, and what is their share?

The apartment inherited from the husband is to be divided among her living heirs. Those of her children, male or female, who died before her, do not inherit. The living sons and daughters inherit, with the male receiving the share of two females. If there is an heir with a prescribed share (husband, father, or mother), their share is given first, and the remainder goes to the children. The children of a daughter who died before her do not inherit anything, due to the presence of direct male descendants. The matter of estates must be referred to the Sharia courts for precise investigation, as there might be wills, debts, or other rights that take precedence over the heirs' rights.
