A father cursing Islam a lot

Q 2: What is the ruling on a father who curses the Din (religion) of Islam? Should he be regarded as a Kafir (disbeliever)? Whenever he is reproached for this and is told that cursing the Din is Kufr (disbelief), he utters the curse again and again. What is the ruling on this father? It is worth mentioning that he pretends to repent to Allah then utters this curse again whenever he gets angry. How should the son deal with him? Should he leave the house although he is young and cannot work? If he leaves the house, he will have to leave his college and engage in any work (Part No. 25; Page No. 277) away from the house.

A: The son must continue advising his father. If advice is of no avail, the son should adapt his life according to his circumstances. If he knows that staying in the house is more beneficial for him, he should not leave it. If he knows that leaving the house is better for him, he will be permitted to leave it and be sure that anyone who fears Allah and keeps their duty to Him, He will make a way for them to get out (from every difficulty) and He will provide them from (sources) they never could imagine. He should not forget the following Ayah (Qur'anic verse) in which Allah (Glorified be He) says, ...give thanks to Me and to your parents. Unto Me is the final destination. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
