'When I first read the Qur'an, I was surprised to find the endless regurgitation of spiteful attacks. The Meccans shouted: “Muhammad, you are an insane, demon-possessed sorcerer, forging the Qur'an.” Allah answered: “My Messenger is not insane, nor is he demon-possessed.” I found this perplexing. Why didn't some enterprising scribe edit these incriminating charges out before codifying the Qur'an? Then I realized that without the raging feud, there was no justification for the scripture's single most repetitive rant: “If you reject Muhammad, Muslims will kill you so that his god can roast you alive.”'
