What is the ruling regarding the estate of a deceased wife who willed that the installments for the apartment be paid from her financial entitlements, and does the inheritance include the entitlements from the savings fund and the death grant, and what is the share of the heirs in the apartment and when is it due?

The deceased's assets must be inventoried, including her share of her parents' inheritance, her earnings, her jewelry, and her post-mortem rights. Then, her debts must be settled. If she made a will for a non-heir, within the limit of one-third, it should be executed. The remainder is divided among the heirs according to Islamic law. If the deceased had male children, her sisters have no right to the inheritance, and the children take the remainder after the husband's share is distributed (with the male receiving the share of two females). If she had no male child, then the sisters are asabat (residuaries) after the shares of the daughters and the husband are distributed. If the money was illicit (e.g., from working in an interest-based bank), it is not permissible for the heirs to take it; rather, it must be distributed for charitable causes. If the heirs are in need, they may take what they need and donate the rest. Matters of inheritance are complex and sensitive, and a mere fatwa (definition) is insufficient. It is imperative to refer to the Sharia (definition) courts to verify all rights, wills, and debts.
