How is the estate of a man who died leaving behind a wife, a son, two daughters, a father, a mother, three brothers, and four sisters divided, given that his father then passed away after him?

A father who dies after his son inherits from him, and his share passes to his heirs. If a person dies leaving a mother, a father, a wife, a son, two daughters, and siblings (brothers and sisters), then the mother receives one-sixth, and the father receives one-sixth due to the presence of a lineal descendant (heir). The wife receives one-eighth due to the presence of a lineal descendant (heir). The remainder is for the son and the two daughters by ta'sib (residuary heirship), with the male receiving the share of two females. The siblings (brothers and sisters) do not inherit due to the presence of the son and the father. The estate is divided into 96 shares: the mother receives 16 shares, the father receives 16 shares, the wife receives 12 shares, the son receives 26 shares, and each daughter receives 13 shares. As for how to divide the share of the deceased father, this requires an accurate enumeration of his heirs.
