According to your friend’s holy book:
Surely those who believe, and those who are Jews, and the Christians, and the Sabians, whoever believes in Allah and the Last Day and does good, they shall have their reward from their Lord, and there is no fear for them, nor shall they grieve. [2:62 cf. 5:69, 22:17]
Good of you to believe in Allah! I am sure you will be rewarded as that book says.
As for me, I am not too worried. This belief in eternal hell or eternal heaven after this current life, will be discarded after the Christ returns and corrects a lot of such misunderstandings. If you are really interested in knowing what to expect in the afterlife, here is a good source:
