How is inheritance divided among a father, mother, husband, daughter, grandson, and granddaughter?

If the heirs are limited to those mentioned, the inheritance is divided as follows: the parents receive one-sixth each, the husband receives one-fourth due to the presence of a descendant heir, and the daughter receives one-half because she is the sole daughter. The original share basis of the inheritance is 12, and it increases to 13. The father receives two shares, the husband three shares, the mother two shares, and the daughter six shares. There is nothing for the sons' children and daughters' children because nothing remains for them after the obligatory sharers. Inheritance matters must be referred to Sharia courts to verify all rights, bequests, and debts before distribution.
