I doubt any, due to the fact that it is the "correct/true religion".
Generally, any Muslim that I have asked this question to has said they do not need to study into other religions, because theirs is the true one. :cover: A little bit unfair, wouldn't you say?
I don't get that feeling from Eselam. I get the feeling that he has done research and read scientific journals. It's just it seems like the only ones he reads, or at least the only ones he pays attention to, are the ones that agree with his religion.
He does know how to think, I'll give him that.
