If it's described as "Egyptian" it could be an oud - similar but not quite the same as a Renaissance/Medieval lute. It might be an idea to find someone to check it out for you, or try to get more info from the shop. If they're honest they shouldn't mind answering enquiries (or admitting they don't know). When/If you have a few more facts, perhaps post them in a lute or early music forum, or (if it's an oud) one dedicated to middle eastern music.
