How is the inheritance divided among the deceased's heirs, who include two sons, two daughters, a wife, and four full sisters?

If the deceased left no heirs except his wife, two sons, and two daughters, then the wife inherits one-eighth due to the presence of a lineal descendant, and the two sons and two daughters inherit the remainder by ta'sib (agnatic succession), with the male receiving the share of two females. The children of the deceased brother and the full sisters do not inherit because they are completely excluded by the son. The estate is divided into 48 shares: the wife receives 6 shares, each son receives 14 shares, and each daughter receives 7 shares.
