Surely every religion with no followers at all in the Middle East, would equally be least prominent. This probably includes, say, Scientology, as well as many others.
The question is a little more meaningful, but harder to answer with certainty, if it implies the least prominent religion with at least some followers in the Middle East. Perhaps, Mandeanism could be that religion, since the number of adherents in the Middle East is probably in the tens of thousands.
