How is the inheritance calculated if the heirs are three sons, one daughter, and one wife?

The inheritance is divided as follows: The wife receives one-eighth due to the presence of a lineal descendant, based on the Almighty's saying: «But if you have a child, then for them is one eighth of what you leave, after any bequest you [may have] made or debt.» The remainder goes to the daughter and the three sons by way of ta’sib (agnatic inheritance), with the male receiving the share of two females, based on the Almighty'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: one share for the wife, two shares for each son, and one share for the daughter.
