Does a deceased son inherit from his father's estate if the father died after him, given that the deceased father has one son and two daughters?

If a son dies after his father but before taking his share of the inheritance, his share does not lapse but rather transfers to his heirs. If a father dies leaving only a son and two daughters, the inheritance is divided among them by 'ta'sib' (residuary kinship), with the male receiving the equivalent of the share of two females. That is, the son receives two shares and each daughter receives one share. The questioner is advised to refer inheritance cases to the Sharia courts for investigation and to confirm the absence of wills, debts, or other heirs.
