How is the inheritance calculated if the heirs are: one son, one grandson (son of the son of the son), one father, one maternal half-brother, one full nephew (son of the full brother), one paternal half-nephew (son of the paternal half-brother), one full paternal cousin, one mother, and one wife?

If the heirs are limited to the wife, father, mother, and son, then the wife receives one-eighth due to the presence of a lineal descendant. The mother and father each receive one-sixth due to the presence of a lineal descendant. The remainder goes to the son by ta'sib (residuary heirship). The inheritance is divided into 24 shares: the wife receives 3 shares, the mother 4 shares, and the father 4 shares. The remainder goes to the son. The remaining relatives of the deceased do not inherit due to the presence of the son. Matters of inheritance must be brought before the Sharia courts to verify the existence of wills, debts, or other rights that take precedence over the heirs' rights.
