This I am actually quite certain of, Ze. Perhaps Islam changed, although you say it can't, but in the Middle Ages they repeatedly said that if you were christian you'd go to hell. Might be for political reasons, I don't know, but they did say that.
Why would the jinn lie about being muslim anyway? What possible advantage could he gain? The only thing he could do is trick people into believing in Islam. Which is what Allah wants them to do.
How could I miss that? That's hilarious. It also looks like these Jinns have nothing better to do than pretend they're muslim. They can only go to the 7th level.
In a lot of ways Dante gets back at people by putting them in hell in his very own novel. That's one of the most important ideas behind it as far as I'm concerned.
I read in the language Dante wrote it in. Can you imagine that? It's neither Italian nor Latin. The beginning is actually quite good though. With the midlife crisis part and everything.
