How is the inheritance divided among the heirs: (1) son, (3) grandson, (4) daughter, (1) granddaughter, (1) wife?

The deceased's wife receives one-eighth due to the presence of a lineal descendant, as Allah Almighty says: "But if you have a child, then for them [the wives] is one eighth of what you leave." The remainder goes to his son and his four daughters by ta'sib (agnatic inheritance), with the male receiving the share of two females, as Allah Almighty says: "Allah instructs you concerning your children: for the male, what is equal to the share of two females." The grandchildren (son's sons and son's daughter) receive nothing because they are excluded by the son, an exclusion of deprivation. The estate is divided into 48 shares: the wife receives 6 shares, the son receives 14 shares, and each of his four daughters receives 7 shares.
