I don't know much about Abu Dhabi, but Mrs Hippo and I were in the UAE for a bit. Now we are back in Qatar (just round the corner). Friends of mine in AD say that it is a fairly relaxed place, but of course some caution and common sense are required. When in doubt, it is a good idea to ask the Arabic and Islamic Studies teachers at your school and they will be happy to help. Too Hot to Handle? was a rather exaggerated piece that appeared in the TES about a year ago and it gave quite a negative impression of life for most teachers in the ME.
