The Qur’an is the primary text of Islam, revealed to the Prophet Muhammed beginning in the year 610 C.E. It was canonicalized between 644 and 656. The Qur’an is required reading for anyone who wants to understand Islam. Qur’an means “The Recital” in Arabic; according to the story, the angel Gabriel commanded Muhammed to “Recite!”.

AN ABRIDGED KORAN recreates the historical order of the Koran of Mohammed’s day. The first chapters start with Mohammed’s first recitation and the last chapters are those he recited before he died. Mohammed’s life gives the Koran clarity, meaning, and order. When the Koran and Mohammed’s life are brought together, the Koran becomes a powerful epic story.
