What is the share of each heir from the deceased's estate, which consists of 19 feddans of agricultural land, 430 square meters of building land, and a three-story house, if the heirs are: 4 sons, a husband, 2 daughters, and a maternal half-sister?

The husband receives one-fourth due to the existence of a lineal descendant, based on the Almighty's saying: "But if they have a child, for you is one fourth of what they leave, after any bequest they [may have] made or debt." The remainder goes to the two sons and two daughters by virtue of 'asabah (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." There is nothing for the sister from the mother's side because she is completely excluded from inheritance. The estate is divided into forty shares: the husband receives ten shares, each son receives six shares, and each daughter receives three shares.
