The Risale-i Nur Collection (Turkish: Risale-i Nur Külliyatı, Ottoman Turkish: رساله نور كلیاتی) is a tafsir (exegesis) on the Qur'an written by Said Nursî, an Islamic Scholar from Bitlis region of Turkey between the 1910s and 1950s. The commentary does not keep to the order of the ayah as is done in classic Islamic exegesis, as it makes comments on their meanings. It is rather a thematic tafsir which deals with the doubts surrounding the basic doctrines and principles of Islam. The collection includes fourteen books.
