Lies. Pure lies. I wasn't going to mention it, but it makes me really mad that there are people so bigoted that I'm somehow in the position of defending Islam, which I despise.
The phrasing is: There is no god but Allah (God), and Mohammed is his prophet.
There's plenty enough in there (The bit about the Mohammed) to criticize without using distortions and lies. About the only point they have going for them is their MONOtheism.
Pay attention to the FACTS. Stop spewing that irrelevant propaganda.
