Iman الْإِيمَان

In review — pending scholar verification

Faith in Islam — defined by the Prophet ﷺ in the Hadith of Jibril as belief in Allah, His angels, His books, His messengers, the Last Day, and divine destiny; understood by classical Sunni scholars as conviction of the heart, affirmation by the tongue, and action of the limbs.

Overview

Iman (Arabic: الْإِيمَان) is the Islamic concept of faith. The Prophet Muhammad ﷺ defined it canonically in the Hadith of Jibril (Sahih Muslim 8) as belief in six articles:

  1. Allah
  2. His angels
  3. His books
  4. His messengers
  5. The Last Day
  6. Divine destiny (qadar) — both its good and its bad

The classical Sunni doctrine, articulated across the works of Imam Ahmad ibn Hanbal, Imam al-Bukhari, al-Lalakaʾi (Sharḥ Uṣūl Iʿtiqād Ahl as-Sunnah), and Ibn Taymiyyah (Kitāb al-Imān), holds that Iman comprises three interlocking components: conviction of the heart (taṣdīq al-qalb), affirmation by the tongue (iqrār bi-l-lisān), and action of the limbs (ʿamal bi-l-jawāriḥ). On this view, righteous deeds are part of Iman; Iman itself increases with obedience and decreases with sin.

Iman is paired by the Quran consistently with righteous action — "those who believe and do righteous deeds" appears more than fifty times. The verbal declaration of Iman is the Shahada: la ilaha illa Allah, Muhammadun rasul Allah. The Quran identifies Iman in Allah and the Last Day as the two pillars repeatedly invoked alongside acts of devotion (e.g., Surah Al-Baqarah 2:177).

Etymology and meaning

The word īmān derives from the Arabic root ʾ-m-n ("to be safe, secure, trustworthy"), giving the verbal noun sense "to grant security to, to give credence to, to trust". It is from the same root as amānah ("trust, deposit"), amīn ("trustworthy, faithful"), and āmana (the Form IV verb, "to grant security to / to believe in"). The implication is that the believer extends trust and inner security to the Object of belief: faith is not blind assent but considered, settled trust.

The Hadith of Jibril

ʿUmar ibn al-Khaṭṭāb said: While we were sitting with the Messenger of Allah ﷺ, a man came whose clothes were exceedingly white and whose hair was exceedingly black. No traces of journeying were visible on him, and none of us recognised him. He sat in front of the Prophet ﷺ, leaning his knees against his knees, placing his palms on his thighs, and said: "O Muhammad, tell me about Islam." The Messenger of Allah ﷺ said: "Islam is to testify that there is no deity but Allah and that Muhammad is the Messenger of Allah, to establish prayer, to give zakat, to fast Ramadan, and to perform pilgrimage to the House if one has the means to do so." The man said: "You have spoken the truth." Then he asked: "Tell me about Iman." He ﷺ said: "Iman is to believe in Allah, His angels, His books, His messengers, the Last Day, and to believe in divine destiny — both its good and its bad." He said: "You have spoken the truth." Then he asked: "Tell me about Iḥsān." He ﷺ said: "Iḥsān is to worship Allah as if you see Him; for though you do not see Him, He sees you." — Sahih Muslim 8 (the Hadith of Jibril)

This hadith, taught as the second of an-Nawawi's Forty Hadith, establishes the canonical structure of Islamic religious life: Islam as outer practice, Iman as inner belief, and Iḥsān as the spiritual excellence that fuses them.

The six articles of Iman

1. Belief in Allah

Affirming the existence, oneness, and sovereignty of Allah in His Lordship, in His sole right to worship, and in His unique names and attributes. This is Tawhid, the foundation of all Islamic doctrine.

2. Belief in the angels

Affirming the existence of the angels (al-malāʾikah) — created from light, neither male nor female, in continuous obedience to Allah (Surah At-Tahrim 66:6). Foremost are Jibril (Gabriel, conveyor of revelation), Israfil (the Trumpet), Mikaʾil (Michael, rain and provision), and the angel of death, Malak al-Mawt.

3. Belief in the books

Affirming that Allah revealed scriptures to His messengers — including the Tawrāh to Musa, the Zabūr to Dawud, the Injīl to Isa, the Ṣuḥuf to Ibrahim and Musa, and the Quran to Muhammad ﷺ. The Quran affirms the divine origin of the earlier scriptures while teaching that they were partly preserved and partly distorted (taḥrīf) before Islam.

4. Belief in the messengers

Affirming that Allah sent prophets and messengers to every nation (Surah An-Nahl 16:36) — beginning with Adam and ending with Muhammad ﷺ as the Seal of the Prophets — and that all of them called to Tawhid.

5. Belief in the Last Day

Affirming the Day of Judgement in all its stages: the Trumpet, resurrection, gathering, the records of deeds, the Scale, the Bridge, and the eternal abodes of Paradise and Hell.

6. Belief in divine destiny (Qadar)

Affirming that Allah's knowledge encompasses everything that has been and will be; that He has written it in the Preserved Tablet (al-Lawḥ al-Maḥfūẓ); that He has willed it; and that He has created it. The classical formulation has four levels: knowledge (ʿilm), writing (kitābah), will (mashīʾah), and creation (khalq). Belief in qadar is the engine of tawakkul — reliance on Allah — without erasing human responsibility, since the Quran also affirms human freedom of action (Surah Al-Insan 76:3, Surah Ash-Shams 91:7–10).

Components of Iman

Imam al-Bukhari titled the second book of his Ṣaḥīḥ "Kitāb al-Imān" and devoted its chapters to the proposition that Iman is speech and action. The classical position can be summarised:

  • Heart (qalb) — conviction (taṣdīq) and submission (inqiyād); without this, mere outward profession is hypocrisy.
  • Tongue (lisān) — verbal affirmation, the Shahada, and remembrance of Allah.
  • Limbs (jawāriḥ) — outward actions of worship and ethics.

Each component reinforces the others. Iman in the heart manifests in speech and action; speech and action sustain Iman in the heart. The Mu'tazilah and Khawarij denied this graded view (the Mu'tazilah holding the major sinner is in an "intermediate state"; the Khawarij holding any major sin removes Iman entirely); the Murji'ah held the opposite extreme that Iman is only conviction and action is irrelevant. The Sunni position threads the middle: action is part of Iman, but Iman is not lost by every sin.

Increase and decrease

The Sunni view, with abundant Quranic and hadith support, is that Iman increases with obedience and decreases with sin:

"The believers are only those who, when Allah is mentioned, their hearts become fearful, and when His verses are recited to them, it increases them in faith (zādathum īmānan); and upon their Lord they rely." — Surah Al-Anfal 8:2

Compare also Surah Al-Tawbah 9:124, Al-Fath 48:4, and Al-Mudaththir 74:31 — the Quran uses the verb zāda ("increase") in connection with faith repeatedly. The hadith on adultery — "the adulterer is not a believer at the time he commits adultery" (Sahih al-Bukhari 2475) — is interpreted classically as: at that moment his Iman is so diminished that he is, functionally, not living as a believer, though he has not necessarily exited Islam.

Quranic references on Iman

  • Surah Al-Baqarah 2:177 — "Righteousness is not turning your faces toward the east or the west, but righteousness is one who believes in Allah, the Last Day, the angels, the Book, and the prophets…" The verse of righteousness, summarising five of the six articles.
  • Surah Al-Baqarah 2:285 — believers' confession of belief in Allah, His angels, books, and messengers.
  • Surah An-Nisa 4:136 — "O you who have believed, believe in Allah and His Messenger and the Book that He sent down upon His Messenger…"
  • Surah Al-Anfal 8:2–4 — signs of the true believers.
  • Surah Al-Mu'minun 23:1–11 — qualities of successful believers.
  • Surah Al-Hujurat 49:14–15 — distinguishing between Islam and Iman.
  • Surah At-Tawbah 9:124 — Iman increases with hearing revelation.
  • Surah Al-Fath 48:4 — Allah's descent of sakīnah (tranquility) increasing the believers in Iman.
  • Surah Al-Aʿraf 7:179 — the heart that does not understand reduced to the state of cattle.

More hadith on Iman

Anas ibn Malik reported the Prophet ﷺ said: "None of you truly believes until he loves for his brother what he loves for himself." — Sahih al-Bukhari 13; Sahih Muslim 45
Abu Huraira reported the Prophet ﷺ said: "Iman has seventy-odd branches — the most exalted of which is the saying of la ilaha illa Allah, and the lowest of which is removing a harmful thing from the road; and modesty (ḥayāʾ) is a branch of Iman." — Sahih al-Bukhari 9; Sahih Muslim 35
Abu Saʿid al-Khudri reported the Prophet ﷺ said: "Whoever among you sees an evil, let him change it with his hand; if he cannot, then with his tongue; and if he cannot, then with his heart — and that is the weakest of Iman." — Sahih Muslim 49

Opposites of Iman

  • Kufr — disbelief: rejection of any of the six articles. See Kuffar.
  • Nifāq — hypocrisy: outward profession of Iman with inner disbelief; the Quran identifies it as a graver sin than open disbelief (Surah An-Nisa 4:145).
  • Shirk — associating partners with Allah, the antithesis of the first article.
  • Riddah — apostasy from Islam after belief.

Significance

Iman is the foundation upon which all Islamic practice is built. Without it, outward acts are formally invalid; with it, even the smallest act becomes accepted. The Prophet ﷺ said: "Whoever says la ilaha illa Allah sincerely from his heart will enter Paradise" (Sahih al-Bukhari 99). The Quran identifies the goal of religious life as the strengthening of Iman until it permeates every act, giving rise to iḥsān — worship of Allah as though one sees Him.
