"John, I'm Scared to Doubt Because I Might Go to Hell"

Someone recently wrote this to me. At one time I too was scared to doubt. But I was never scared of Allah's threat of hell. In fact, I never gave it a thought. Why are people scared of the Christian hell when they have never been scared of the Muslim hell? When Muslims leave their faith they are just as scared of Allah's hell as Christians seem to be about Yahweh's hell. If Christians are not scared of Allah's hell then they should not be scared of Yahweh's hell. Both conceptions of hell are culturally inherited beliefs.
