I worked with a lady named Nor once, she was very lovely and sweet. She wasn't Muslim either, and I never got around to asking about her heritage. It's a very lovely, easy name :)
According to (http://www.babynames.ch/Info/Name/naNor) Nor is a very popular name in Malaysia among females, it ranked 1st place in 2012, 2013, 2014 and 2015 (4 years in a row)!
