Question: And also, his father does not pray, and when he advises him, he says: “I know more than you.” So what do you advise I do with him?
Response: You mean he does not even know about salaah?! He [claims] he knows more than him, and [yet he] does not know about salaah?!
He has not attained [knowledge], [rather], he has become a compound ignoramus – and refuge is sought in Allaah; [Either that], or he is a savant of misguidance.
So, [despite the calamity of the situation], he is [still] required to maintain sincere advice to his father, and [remind him] with the fear of Allaah; [Yes], he [should remind him] with the fear of Allaah ‘Azza wa Jall.
So if he refuses, and [if] he is able to separate from him, then he should move out and live away from him, [and] live [separately] by himself. [Live] in a house with his [own] family, or he lives alone by himself.
Yet [throughout], he must maintain his duty, honour and kindness towards his father, even if he is living [separately] in another house; Yes.
