How is the inheritance divided among the father, mother, son, daughter, and full brother?

If the heirs are limited to those mentioned, then the mother and father each receive one-sixth due to the presence of a lineal descendant heir. The remainder goes to the son and the daughter by ta'sib (residuary inheritance), with the male receiving the share of two females. The full brother is excluded from inheritance due to the presence of the father and the son. The estate is divided into 18 shares: 3 for the mother, 3 for the father, 8 for the son, and 4 for the daughter. Inheritance cases must be referred to Sharia courts due to their complexity and to ensure there are no other heirs, debts, or bequests that take precedence over the heirs' rights.
