…I don’t want to waste those 4 years of mine. Each year I have to pay a fee of around 1800 euro
which I don’t want to. I can collect that money and go to hajj instead. He now doesn’t talk to me at all. what is the Islamic ruling on this? And I also don’t want to become an Engineer but I want to do something for this deen and I want my akhira to be good.

This is your choice to make and he has no right not talking to you. Be respectful, obedient and try to soften his heart but continue to study Islam.

I told my father that I will study Islam and not Engineering. He got angry and stopped talking to me. He says whether you study engineering which is 4 years and then Islam or you never talk to me again. ..
