Also not all people with Islamic names are Muslim. Today I met a non Muslim named Muhammad. I suspect they are more. Some of the minority race groups give their children names that they do not see associated with Caucasians. The fad at the moment seems to be Arabic or Japanese names. There are also Arabic people that are not Muslim and often they will have Islamic names. So the best guide line is there is no need to change a name unless it is anti-Islamic.
