"islam" is false religion that speaks with no truth or authority and cannot even tell you if their false prophet is in heaven. Read Romans chapter 5.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
