Q. A woman is divorced with a daughter. She has remarried a divorced man who has a son. Can the (previously) divorced man’s son marry the (previously) divorced woman’s daughter?
A. Step children are non-Mahrams to one another. Hence, it is permissible for the stepfather’s son to marry the stepmother’s daughter. (Hindiyyah 6/472)
