How is inheritance divided among four sons, a grandson, two daughters, and a wife?

If the deceased leaves behind only a wife, and male and female children, then the wife receives one-eighth (1/8) due to the presence of inheriting offspring. Allah (Exalted be He) says: "But if you have a child, then for them [the wives] is one eighth of what you leave, after any bequest you [may have] made or debt." The remainder is for the sons and daughters by way of ta'sib (residuary heirship), with the male receiving the share of two females. Allah (Exalted be He) says: "Allah instructs you concerning your children: for the male, what is equal to the share of two females." The grandson does not inherit in the presence of a son, as he is completely excluded by the son.

The inheritance is divided into eighty shares. The wife receives ten shares (one-eighth), each son receives fourteen shares, and each daughter receives seven shares.
