"Islam is often seen as a monolith, when it is as diverse as any other tradition, with followers running the gamut from modernizers to traditionalists. Some commentators talk as if the world of Islam was more or less identical with the Arab world -- whereas in fact a majority of Muslims are not native Arabic speakers. The most populous Muslim countries are to be found in non-Arab Asia -- from Indonesia through South-East and South Asia to Central Asia, Iran, and Turkey, which of course is both in Asia and Europe. There are many predominantly Muslim countries in sub-Saharan Africa, and large minorities of Muslims are to be found on every continent."
