Most people do not fall into a static category of religion, like my friend who asked me if I think ISIS represents Islam. She did not wish to be misrepresented. Islam is not one thing, just as Judaism is not one thing, just as Christianity is not one thing.
Muslims now number over two billion people, and the number is rising. Often we associate Islamic authority and teaching with the Arab world, but most of the world’s Muslims are far from this region. Eighty percent of Muslims are non-Arab, and the most populous Muslim country is Indonesia.
