What are the shares of the deceased's heirs who left behind two living wives and seven sons, and does a wife who died before him inherit?

A stepmother who passed away before her husband has no share in the inheritance because whoever dies earlier does not inherit from the one who dies later. If a father dies leaving behind only two wives and seven sons, the two wives receive one-eighth, divided equally between them, due to the presence of children. The remainder goes to the seven sons, divided equally among them. The inheritance is divided into 16 shares: one share for each wife, and two shares for each son. Inheritance matters should be referred to the Sharia courts for investigation, as there might be wills, debts, or rights that take precedence over the heirs' rights.
