"According to this teaching there has not been a single people at any time in history or anywhere in the world who have not had a warner from God, a teacher, a prophet. According to the Quran there have been prophets at all times and in all countries. India, China, Russia, Afghanistan, parts of Africa, Europe, America—all had prophets according to the theory of divine guidance taught by the Quran. When, therefore, Muslims hear about prophets of other peoples or other countries, they do not deny them. They do not brand them as liars. Muslims believe that other peoples have had their teachers. If other peoples have had prophets, books, and laws, these constitute no difficulty for Islam."
