Pronounced “ku-RAHN.” The holy book of Islam, which Muslims believe is the direct word of God as dictated in Arabic to Muhammad by the Angel Gabriel during the month of Ramadan beginning in 610 to about 632. The Quran contains laws for society, as well as descriptions of heaven and hell and warnings on the end of the world. It also includes stories of figures found in the Hebrew and Christian Scriptures, but Muslims believe the Quran supersedes those holy writings. Quran is the preferred spelling and is capitalized in all references. The spelling Koran should only be used if it is in a specific title or name.
