Atheists, how would you explain these Christian testimonies?

[FatAndFaithless]

Not responding to the events in the OP specifically, but in a parallel vein. Approaching any claimed phenomena with the question "How do you explain this?" isn't the best thing to do. It's not the job of a skeptic to claim an explanation, a skeptic just responds to proposed explanations - asking for evidence, etc. If we knew exactly nothing about the muslim man in the OP, we'd simply say "we don't know" when asked for an 'explanation.' It's the burden of the claimant to support his claim, not the burden of the skeptic to propose an alternative. Just stating "we don't know" is the most honest thing you can do if an explanation is not forthcoming or apparent.
