But the question is, what's the difference between the adjective muslim and the adjective islamic.

I don't know the answer.

I would say that "muslim" refers to a person, "islamic" refers to something pertaining to Islam. An example would be "islamic" doctrine, or "islamic" thought. A muslim would follow islamic doctrine.

none. other than the spelling. Moslem, Islamic, Muslim all the same thing
