What is the division of inheritance among: a mother, a wife, three sons, a daughter, a grandson (son of a son), two full brothers, three full sisters, and a full brother's son?

If the deceased left behind only a mother, a wife, a daughter, and three sons, then the mother receives one-sixth due to the presence of a lineal descendant, and his wife receives one-eighth due to the presence of a lineal descendant. The remainder goes to the daughter and the sons by ta'sib (residuary inheritance), with the male receiving the share of two females. The other mentioned heirs receive nothing, as they are excluded by the direct son. The inheritance is divided into 168 shares: the mother receives 28 shares, the wife receives 21 shares, the daughter receives 17 shares, and each son receives 34 shares. It is advisable to consult the Sharia courts regarding matters of inheritance, as there may be bequests or debts that the heirs are unaware of.
