All three are totalizing, in that adherence to the Deity is supposed to be the central defining trait of one's belief, worldview and praxis. Historically, strains of each have been more or less inclined to the universal missionizing impulse, although it is correct that this tenet has generally been much stronger in Christianity and Islam than in Judaism. (For an interesting side note on missional Judaism, take a look at the Khazar Khanate, although even this was somewhat accidental.) "World conquest" is the wrong lens through which to understand the focus of these religions. More accurate (if perhaps not less threatening/insulting to non-Christians/Muslims) would be that adherents of these faiths are attempting to inform non-adherents of the established fact that the world, and indeed the cosmos, has already been "conquered" by God.
Thucy, I do not believe you can define the importance of a faith merely by the number of its followers, but I understand your point that currently Judaism is much smaller numerically than either Christianity or Islam. Calling Jews the monotheistic Cajuns is not anti-Semitic, but it is rather dismissive. We've gotten rather far from your original point here, which was to share a spectacular-sounding spiritual experience and to understand how Muslims might perceive it.
BTW, I was on those Dakar beaches many years ago during a jellyfish swarm. Crazy.
