How do I get this Muslim at work to stop talking to me? Any advice I don't want to get fired for being mean to the Muslim guy at work because I know they treat him special. I just need him to stop trying to talk to me. Bad enough I have to work with him.

One way to get him to stop talking to you would be to actively ignore him when he addresses you. Don't make eye contact, don't respond, and avoid him when you can. It will be uncomfortable at first, but it will send a signal that you aren't receptive to his attention. 
It may also be helpful to remind yourself that talking to him is a professional courtesy—just because he is Muslim does not mean you need to reciprocate his attempts to be friendly.
