Since I am of the view that not believing in any god came before believing in one, it is impossible for any non belief to come from any religion.

However, if you take the extreme view of Athiesm and say that it is still a standpoint of belief, albeit in terms of denial, (an argument to ignorance but we'll let it slide) then having that kind of non belief arise as a derivative of, consequence of, or reaction to a religion is something I can see happening.
