How is the inheritance divided among three sons, a mother, a daughter, and a wife?

If the heirs are limited to those mentioned, the mother receives one-sixth due to the presence of a lineal descendant, and the wife receives one-eighth due to the presence of a lineal descendant. The remainder is distributed among the sons and the daughter by way of ta'sib (residuary inheritance), with the male receiving the share of two females. The estate is divided into 168 shares: the mother receives 28 shares, the wife 21 shares, the daughter 17 shares, and each son 34 shares. We emphasize the necessity of referring inheritance matters to the Shariah courts to verify the existence of wills, debts, or other rights that take precedence over the heirs' rights.
