How are the legal shares and portions of a deceased father's estate distributed among his three sons and two daughters, given that one of his sons has since passed away, leaving behind a wife and two daughters?

If the father dies leaving three sons and two daughters, his estate is divided among them by ta'sib (agnatic inheritance), with the male receiving the share of two females. Thus, it is divided into eight shares (two shares for each son and one share for each daughter).

If one of the sons then dies, leaving a wife, two daughters, two brothers, and two sisters (full siblings or paternal siblings), the share of the deceased son (which is two shares from the first father's estate) is divided among these heirs. This issue falls under the category of munasakhat (successive inheritances), and the outcome of its division is that the estate of the deceased son is divided into 576 shares, such that each brother (who is a son of the first deceased) receives 154 shares, each sister (who is a daughter of the first deceased) receives 77 shares, the wife of the deceased son receives 18 shares, and his two daughters receive 96 shares (48 shares for each).
