What I have heard so far (and since the authorities are not making any of this public, everyone will of course cry rumor...but here goes):

A bunch of congregants who belonged to an evangelical church here called Grace Fellowship have been deported. MANY families -- including people who worked for big oil companies and US universities -- have been affected.

Story has it that some members of the church were praying for a sick Qatari (and yes, they do the "laying on of hands" bit), who then recovered and converted to Christianity.

People have been actively discouraged from speaking about this incident publicly. My source said that her HR person told people not to even discuss the matter on the telephone (for fear of what? CID listening in and arresting/deporting some more folks?).

If they were prosletyzing, which is against the law here, then fair enough. But if they're not going to make everything public and allow people to know about what's happening, then there are going to be rumors and innuendo.
Who knows? Maybe the guy converted of his own free will upon his recovery...just because a bunch of Christians pray for you doesn't constitute prosletyzing in my book. But then again -- we won't really know what happened until people speak out about it.
