6The 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 The Holy Quran is the Holy Book or the Scripture of the Muslims. It lays down for them the law and commandments, codes for their social and moral behaviour, and contains a comprehensive religious philosophy. The language of the Quran is Arabic. It is a compilation of the verbal revelations given to the Holy Prophet Muhammad over a period of twenty three years.
