“Superimposed on the notion of a God who speaks with men in order to command them to do something or to forbid them to do something was that of the Absolute Book, of a Sacred Scripture.
For Muslims, the Koran, (also called “The Book,” al-Kitab) is not merely a work of God, like men’s souls or the universe; it is one of the attributes of God, like His eternity or His rage.
In chapter XIII we read that the original text, the Mother of the Book, is deposited in Heaven.
Muhammed al-Gazali, the Algazel of the scholastics, declared: “The Koran is copied in a book, is pronounced with the tongue, is remembered in the heart and, even so, continues to persist in the center of God and is not altered by its passage through written pages and human understanding.”
George Sale observes that this uncreated Koran is nothing but its idea or Platonic archetype; it is likely that al-Gazali used the idea of archetypes, communicated to Islam by the Encyclopedia of the Brethren of Purity and by Avicenna, to justify the notion of the Mother of the Book.”
