ANSWER:

You must not openly talk to him or “advise’ him like this as he’s your father and you’re not his mother! His getting angry at you is natural. 

You can send beneficial authentic Islamic videos prohibiting such sins but just randomly in groups that you both are in, without hinting that you’re sending these to him. 

Make a lot of dua but never directly confront him. 

My father commits many sins (gossiping, cursing, smoking, wasing time on his laptop 24/7 movies, women, Fb) but when I try to advise him he gets angry and he doesn’t allow me to speak. I heard from another Shaikh that one shouldn’t sit with his/her parents when they are engaged in sins, but my dad is constantly smoking, on his laptop and sometimes gossips, does that mean I can’t sit with him?

Does a man have equal financial duty towards his wife & children and widowed mother?My brother does not give monthly pocket money to my mother for her expenses (she lives alone).In case he buys (say) a flight ticket for my mother, he cuts that amount & then gives her the balance monthly pocket money. She has no income of her own.He however pays for his wife&kids as required/is not stingy with them
