What is the share of each heir among the son, daughter, and wife of the deceased?

If the deceased leaves behind only a wife, a son, and a daughter, the wife receives one-eighth due to the presence of a lineal descendant. The remainder goes to the son and daughter by way of ta’sib, with the male receiving the share of two females. The inheritance is divided into 24 shares: the wife receives 3 shares, the son 14 shares, and the daughter 7 shares.
