[Treatise For The Seekers Of Guidance] The translation, notes, and commentary of Imam al-Harith al-Muhasibi’s Risala al-Mustarshidin (Treatise For The Seekers Of Guidance) by Zaid Shakir is intended to serve as a layman’s guide to Islamic spirituality. Al - Muhasibi presents most of the major ideas that would both serve as the basis for a full program of spiritual development and comprise an insightful overview of a system of Islamic moral psychology. He examines in great depth and penetrating insight the psychological motivations and justifications for moral thought and action and correspondingly the associated bases of immorality. In so doing, he has provided a road map that any person can follow to overcome the guiles of his fundamental enemies: the world, the ego, the whims of the soul, and Satan.
