[Squirrelloid]

Islam is slightly more conflicted on the 'non-believers' part than Christianity. There's at least one Sura which claims that 'people of the book' (Christians and Jews) can achieve paradise, because they do worship the true god. Of course, there are also passages which imply the converse, so as I said, conflicted. Christianity, by comparison, is very much 'believe or fry'.

(Actually, this gets to the heart of a difference between the religions. Islam is not about belief in the way Christianity is. Its about submission to God and refusing the path of hubris - that you can get along without God. Orthopraxy is far more important than orthodoxy.)
