The document discusses the concept of nafs in Islam. It defines nafs as the soul or self in Arabic. The Quran conveys that the nafs is something that must be nurtured and regulated so it can progress from inciting evil to a peaceful state. It describes three stages of the nafs: 1) The inciting nafs which commands sin, 2) The self-accusing nafs which reproaches itself, and 3) The peaceful nafs which is reassured and pleasing to God. It says remembering God assures the hearts of believers and brings peace to the soul. Those who believe and do good deeds will find comfort and reward.
