The history of the text of the Qur'an has been a longstanding subject of interest within the field of Islamic Studies, but the debate has so far been focused on the Sunni traditions about the codices of Caliphs Abu Bakr and 'Uthman b. 'Affan. Little to no attention has been given to the traditions on 'Ali b. Abi Talib's collection of the Qur'an.
This book examines both Shi'i and Sunni traditions on the issue, aiming to date them back to the earliest possible date and, if possible, verify their authenticity. To achieve this, the traditions are examined using Harald Motzki's isnad-cum-matn method, which is recognised as an efficient tool in dating the early Islamic traditions and involves analysis of both matn (text) and isnad (chain of trans-mission) with an emphasis on finding a correlation between the two.
