This book summarizes all the topics in the Risale-i Nur, the author's great multivolume commentary on the Qur'an, and provides an outline for the later, more famous and massive treatise. Now available in English, it offers an overview of the material treated in the Risale-i Nur and an opportunity to browse through brief entries such as Flower, Spark, and Whiff, each of which is a keyword linked to a passage in the Qur'an or a figure of speech in a theological argument.
