How is the inheritance divided among the deceased's heirs: a wife, two sons, and three daughters?

The wife receives one-eighth due to the existence of a lineal descendant, based on Allah's saying: "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 goes to the sons and daughters by way of ta'sib (residuary heirship), with the male receiving the share of two females, based on Allah's saying: "Allah instructs you concerning your children: for the male, what is equal to the share of two females." Thus, the inheritance is divided into eight shares: the wife receives one share, each son receives two shares, and each daughter receives one share. The matter of inheritances must be referred to the Sharia courts for investigation to determine if there are any bequests, debts, or rights that take precedence over the rights of the heirs.
