The answer to the first contest submitted by Skip is Gamla Stan in Stockholm Sweden (not an Muslim country). It is the old part of the city and the location of the royal palace.
To participate, just make your guess in the comments section for each photo. Guesses will be held until the end of the contest, when they will all be made public. Anything and everything is fair game for getting a correct answer. Each contest will last 2-3 days, so submit your guess as soon as you have an idea.
