and they granted you entry subject to their terms and conditions, then its binding on you.
Can you provide a document with these terms and conditions which a tourist have to sign?
Why even go there? What in the world are few places where you can relax without such an extreme? I think people should avoid such trips.
I think if tourists would be warned about UAE Sharia laws, no one would travel there. Therefore UAE govt deceives tourists, then imprisons them for breaking some law which they have no way to know!
In these cases, a country from which a tourist come, can roughly demand to immediately release captured tourist. If UAE disagrees, threat them with a destiny of Saddam Hussein!
UAE will release this prisoner and likely ban entry for all citizens of prisoner's country and other tourists who planned to visit UAE will spent money in home country. Profit!
