How is the estate of deceased parents and son divided among the son's children (two sons and a daughter) and his sisters (two), which includes agricultural and uncultivated lands, and a dwelling?

Firstly: If a man dies, leaving behind a wife, a son, and two daughters, the wife receives one-eighth, and the remainder is for the son and the two daughters, with the male receiving the equivalent of two shares of a female.

Secondly: After the son's death, his inheritance is divided among his heirs. His mother receives one-sixth, and the remainder is for his children, with the male receiving double the share of the female. His two sisters receive nothing.

Thirdly: After the mother's death, her two daughters inherit two-thirds, and the remainder is for the son's children, with the male receiving the equivalent of two shares of a female.

Fourthly: Whatever portion of the land or property can be divided should be divided, and each heir given their share. Whatever cannot be divided should be valued or sold, and each heir given their share from the total value.
