How is the estate of a father to be divided who passed away, leaving behind four sons, five daughters, and a wife, then one of the sons (who was disabled and unmarried) passed away, and then the wife passed away?

If a father passed away, leaving behind a wife, four sons, and five daughters, and then one of the sons passed away, followed by the mother, and the heirs of the sons and the mother are the same as the heirs of the father, then the inheritance is divided directly among the living heirs (the three sons and the five daughters), as if the father had passed away leaving only them. The inheritance is divided such that the male receives the share of two females, making 11 shares in total: two shares for each son and one share for each daughter. Issues related to inheritances must be submitted to the Sharia courts for investigation.
