The role of a son with his parents when they are in error and disobedience

Question:
May Allah reward you. Honorable Shaykh, this questioner says in his question: There may be someone whose father or mother is misguided or not on the right path. What is the son's role with his father or his mother? Does he call them to the truth and to guidance, or

Answer:
Without a doubt, the right of the parent is great, and the son must advise his father regarding sins. If the parent is a mushrik (one who associates partners with Allah), he calls him to Islam and to tawhid (the oneness of Allah), because he is the most deserving of being called and shown compassion. He strives to guide him by exerting the means, and the Guide is Allah (Mighty and Majestic). But he calls him, explains to him, and strives for his entry into Islam. If the parent is a sinner, he advises him to repent and abandon sins, because he is the most deserving of people of his advice and of his concern for him regarding sins. However, if the parent persists in what he is doing, the son is free of blame if he has advised him and explained to him; his blame is cleared. But dutifulness to the parent remains, so he is dutiful to him even if he is a disbeliever, even if he is a mushrik, even if he is a sinner; he is dutiful to his parent, as He (Mighty and Majestic) said: . Yes.
