The Quran is, in its own words, “light,” which means that it is self-manifesting, with no need of an external source of illumination; other things need light to become visible and manifest. With it God guides those who pursue His pleasure to the ways of peace, and brings them out from darkness into light by His will, and guides them to a straight path.
