Well, by sheer luck it will be correct about some things, obviously. But so much of it is utter bullshit. I'm coming from a Bible perspective here, but the same is bound to be true for the Qu'ran. And think about it, would it really be likely that the Qu'ran is right and all others are wrong?
Come on.. That point of view is so ridiculous it hardly even merits serious debate. And when the Qu'ran, or Bible or whatever, is wrong about some things what is to say it's not wrong about other, fundamental things as well?
The entire idea of believing in a book written over a 1,000 years ago, assuming that it was inspired by God, despite there being considerable gaps of knowledge and even downright mistakes in it, does not sit very well with me. I fail to understand why any rational, educated human being, living in the 21st century, would even contemplate that Allah is real.
