Assalamu Alaykum

This question has been on my mind for quite some time now and i thought i would ask it here. Sorry if it has been already asked. I know that according to Islam a Muslim will eventually end up in Heaven after being punished for his sins. Now the question i have is lets say a Christian man(or any other religion) who follows the Bible and is a very good person who does all sorts of kind acts and is a very peaceful person. He follows the Bible as Muslims follow the Qu'ran He gives to charity etc... does he end up going to hell? Because as i far as i know its all Muslims will eventually end up in Heaven.

Please correct me if I am wrong and I hope I haven't offended anyone. I was just thinking about this question for quite some time now.

Jazaka Allahu Khairan
