How is the estate of a man who died leaving a father, five brothers, two sons, three daughters, and a wife to be distributed, knowing that one of his sons is a minor with special needs, and there is no debt or will?

If a person dies and leaves behind his father, his brothers, his wife, his two sons, and his daughters, and no one else, then his father receives one-sixth due to the presence of a lineal descendant, and his wife receives one-eighth due to the presence of a lineal descendant. The remainder goes to the two sons and daughters by ta'sib, with the male receiving the share of two females. The brothers receive nothing because they do not inherit in the presence of the father or a son. The estate is divided into 168 shares.
