The disease and the cure

This book was a response to a question posed by an individual who was afflicted by a calamity, finding himself in a dire and needy state.  He acknowledged to himself that if he failed to rid himself of this ailment it would destroy him in this life and the next life.  He had endeavoured to relieve himself of this affliction, but its severity and intensity grew.  Consequently, Ibn al-Qayyim diagnosed his condition and understood the request within the question, providing an answer that was detailed and appropriate.  Thus, this classical work is suitable for all places and times.
