depends if he died a christian.smhSlightly off topic
I knew this Nigerian kid who was born a Muslim.And stayed a Muslim all his life
That is until he turned Christian and died a week later Wallahi
What will happen to him do you think
Bv it is wrong to say so and so will go to hell, unless that person is doing such things that are clearly outside of all Islamic beliefs. But to such and such a person is going to hell is different, unless it's for nuanced things where it is needed knowledge. But to say a murderer, rapist, Kaffir, adulterer, etc that well known major sins, and there is no repentance, you should believe that those are actions that lead you to hell as principles, but individual cases differ as it is left ultimately to Allah to answer that question.
