ANSWER:

How can one know that Allah decreed that he would die in that particular manner? 

It is the individual who chose to end his life and he chose to enter hell for eternity!

He could have chosen to be an imam leading people in prayers but he didn’t! 

If Allah had already decided, for how much time a person will Live in this World, Then why Suicide is a Sin ?

Only when Allah gives hidayah a person can convert or do good deeds but if Allah doesn’t will to give hidayah to that very person then how is it the mistake of a non believer. Even if we pray for them if Allah doesn’t will then it’s not the mistake of the non believer. It’s all upto Allah to give hidayah??
