How is inheritance divided among: a son, 2 grandsons, 3 daughters, and 3 granddaughters?

If the heirs are limited to one son and three daughters, then the inheritance is to be divided among them by taʿṣīb (agnatic succession), with the male receiving the share of two females, in accordance with Allah's saying: "Allah instructs you concerning your children: for the male, what is equal to the share of two females." There is nothing for the grandchildren (sons and daughters of the son) because they are excluded by the deceased's direct son. Thus, the inheritance is divided into five shares: two shares for the son, and one share for each daughter.
