The Koran: A Very Short Introduction
How the Qurʾan came into being and why it looks the way it does has proven to be a continual focus of attention for scholarship. Most accounts accept the basic framework of the Muslim memory, with the role of Muhammad as the recipient of revelation and the role subsequent caliphs in bringing the text together clearly separated. Some scholarship has wanted to challenge the originality and source of the text itself, tracing it to other religious communities (especially Christian: Lüling 2003; Luxenberg 2007). Others have tried to refine the Muslim accounts of revelation and collection.
