How is inheritance divided among 3 sons, 4 daughters, and a wife?

If the deceased leaves behind only a wife, sons, and daughters, then the wife receives one-eighth (1/8) due to the presence of inheriting offspring. Allah states: "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 ta'sib (residuary heirship), with the male receiving the share of two females. Allah states: "Allah instructs you concerning your children: for the male, what is equal to the share of two females."

The inheritance is divided into eighty shares: - For the wife: ten shares (one-eighth). - For each son: fourteen shares. - For each daughter: seven shares.
