However, in the course of doing that, al-Qurṭubī examines all the relevant sciences necessary, such as the ḥadīth pertaining to the āyahs, events in the sīrah, what the Companions, their Followers and other noted people of knowledge said about the āyahs, essential aspects of Arabic etymology, syntax and usage, copiously illustrated by examples, and much more.

As its title, al-Jāmi' li Aḥkām al-Qur'ān - The General Judgments of the Qur'an, suggests, its main focus is on the rulings and judgments to be found in the Qur'ān. The tafsīr of al-Qurṭubī is perhaps one of the most compendious of them all and is certainly among the most famous. As such, it will be of great interest not only to researchers and students of Sufism but also to scholars of comparative spirituality and mysticism. Reconstructing his life in chronological order and providing the most comprehensive appraisal of his works to date, it explores a facet of al-Muhāsibī’s teaching which as yet has not been studied, namely his understanding, concept and methodology regarding the purification of the soul within the Islamic paradigm. Assessing the extent to which the political, social and economic factors played a part in his life and work, Gavin Picken provides a comprehensive overview of his work and its great significance in the development of Islamic spirituality. Although al-Muhāsibī was well known for his skills in many disciplines, including the Qur’ān, Prophetic narration and scholastic theology, it is his mastery in the field of Islamic spirituality and moral psychology for which he is best remembered. This book examines the work of a scholar of this discipline, al-Hārith al-Muhāsibī, who lived and worked during the classical Islamic period under the Abbāsids.

Purification of the soul is a principle that is central to understanding Islamic spirituality but despite this, relatively little has been written explicitly in the Islamic tradition regarding this discrete method of spiritual purification.
