Nafs (The Self / Soul)
Suggest editDefinition
Nafs (نفس) in Islamic theology refers to the self, soul, or psyche of the human being — the locus of consciousness, will, desire, and moral choice. It is the inner dimension of a person that is held accountable before Allah, and its purification (tazkiyah) is one of the central objectives of Islamic spiritual practice. Allah says: 'Successful is the one who purifies it, and failed is the one who buries it in corruption' (Quran 91:9-10).
The nafs is not identical to the ruh (spirit), though the two are related. The ruh is the divine breath that Allah breathed into Adam (Quran 15:29) and about which Allah says: 'They ask you about the ruh; say: the ruh is from the command of my Lord, and you have been given of knowledge only a little' (Quran 17:85). The nafs is the individuated self that experiences, chooses, and is held accountable.
The Three States of the Nafs in the Quran
The Quran identifies three named states of the nafs, representing a spiritual spectrum from the lowest to the highest:
- An-Nafs al-Ammarah bil-Su' (النفس الأمارة بالسوء) — The soul that persistently commands evil. This is the nafs in its raw, undisciplined state, dominated by base desires, heedlessness of Allah, and submission to shaytan. The Prophet Yusuf references this state when he says: 'I do not acquit myself — indeed the nafs is a persistent commander of evil, except when my Lord has mercy' (Quran 12:53). This is the nafs that the believer must struggle against (jihad al-nafs).
- An-Nafs al-Lawwamah (النفس اللوامة) — The self-reproaching soul. Allah swears by this soul in the Quran: 'And I swear by the self-reproaching soul' (Quran 75:2). This is the nafs in a state of internal struggle — it sins and then reproaches itself; it falls and then rises. This middle state is the condition of most believing people and represents genuine moral conscience in action.
- An-Nafs al-Mutma'innah (النفس المطمئنة) — The soul at peace. This is the highest state, in which the nafs has achieved tranquility through closeness to Allah, consistent worship, and victory over desires. Allah addresses this soul directly: 'O soul at peace, return to your Lord well-pleased and pleasing, and enter among My servants, and enter My Paradise' (Quran 89:27-30). This is the goal of the spiritual journey.
Tazkiyat al-Nafs — Purification of the Self
The process of purifying the nafs is called tazkiyat al-nafs and is one of the three explicit functions of the Prophet's mission, as the Quran states: 'He recites to them His verses, purifies them, and teaches them the Book and wisdom' (Quran 62:2). The methods of purification include:
- Consistent prayer (salah): Prayer is described as preventing immorality and wrongdoing (Quran 29:45) — meaning it actively disciplines the nafs.
- Fasting (sawm): The Prophet said: 'Whoever can afford marriage should marry, for it lowers the gaze and guards the private parts. Whoever cannot should fast, for fasting is a shield' (Sahih al-Bukhari 5066) — fasting controls the nafs.
- Dhikr (remembrance of Allah): 'Verily, in the remembrance of Allah do hearts find rest' (Quran 13:28).
- Muhasabah (self-accountability): Regular honest examination of one's intentions and actions.
- Righteous companionship: The company one keeps profoundly shapes the nafs.
Scholarly Treatments
Imam al-Ghazali dedicated the third quarter of his encyclopedic work Ihya Ulum al-Din to the destructive traits of the nafs (muhlikat) and the means of their cure. Ibn al-Qayyim al-Jawziyyah's Madarij al-Salikin maps the entire spiritual path as a journey of the nafs from its lowest state to its highest. Both scholars are in the tradition of the Salaf, who understood that tending to the nafs was not an optional refinement but the very substance of Islamic worship.
