How is the inheritance divided among: a husband, a mother, a son, a daughter, three full brothers, and four full sisters?

If the deceased's heirs are limited to a son, a husband, a mother, and a daughter, then the full brothers and sisters do not inherit, as they are excluded by the son. The inheritance is divided as follows: The mother receives one-sixth due to the presence of a lineal descendant and a number of siblings. The husband receives one-fourth due to the presence of a lineal descendant. What remains after the mother's and husband's shares is divided between the son and the daughter by ta'sib (residuary inheritance), with the male receiving the share of two females. The origin of the estate is twelve, and it corrects to thirty-six shares.
