How can one deal with a father who curses and insults, and prevents his son from celebrating Eid, despite the son's attempts to please him, given that the father is a smoker, does not pray, burdens his son with work responsibilities, and prevents him from praying in the mosque?

This trial requires you to be patient and benevolent towards your father and to strive for his reformation and guidance by frequently supplicating for his guidance and righteousness, and by your patience and dutifulness towards him. You can also seek the help of some people of virtue and knowledge to advise him. And you are not obliged to obey him in preventing you from praying in the mosque.
