This book addresses the matter of morals and purification of the soul. It focuses on the physical and spiritual love of Allah and stresses that all good deeds must emanate from the love of Allah. Any act which is empty of this love is useless. The author discusses the benefits of supplication which is the most effective tool of removing evil thoughts in a person. It was written by the eminent scholar Ibn al Qayyim in Arabic and this is the first time that it is presented to the reader in English.
