The Quran informs us that the natural instance placed inside all people is Monotheism.
30:30 Therefore, you shall devote yourself to the religion of strict monotheism. Such is the natural instinct placed into the people by GOD. Such creation of GOD will never change. This is the perfect religion, but most people do not know.
