What is the ruling regarding a young man raising his voice at his father, who is confronting him because he advised his sisters to stay away from flirting with young men?

What a young man does by advising his sisters and preventing them from speaking to young men is a good deed and falls under enjoining good and forbidding evil. He should continue to do so. If his sisters are doing that, he must stop them and not pay attention to his father's prohibition, for there is no obedience to a creature in disobedience to the Creator. However, he must not raise his voice at his father.
