How is the inheritance distributed among a son, a father, a full brother, four daughters, and a full sister?

If the heirs are limited to those mentioned, the full sister and full brother are excluded by the father and the son. The father inherits one-sixth due to the presence of a male lineal descendant, based on the Almighty's saying: "And for his parents, each of them is to have a sixth of what he left if he had a child" (An-Nisa:11). The remainder goes to the son and the daughters, with the male receiving the share of two females, based on the Almighty's saying: "Allah instructs you concerning your children: for the male, what is equal to the share of two females" (An-Nisa:11).

The inheritance is divided into 36 shares: the father receives 6 shares, the son receives 10 shares, and each daughter receives 5 shares.

Inheritance matters must be brought before the Sharia courts for precise investigation, as there might be an unknown heir, or wills, or debts that take precedence over the rights of the heirs.
