The Six Pillars of Iman

What Are the Six Pillars of Iman?

The Six Pillars of Iman (Arkan al-Iman, أَرْكَانُ الْإِيمَانِ) are the six foundational articles of belief that define faith in Islam. Unlike the Five Pillars of Islam — which govern outward action (Shahada, Salah, Zakat, Sawm, Hajj) — the Six Pillars of Iman govern inward belief. Together, belief and action form the complete structure of the Islamic faith: what a Muslim believes in the heart, and what a Muslim does with the body.

These six pillars were taught directly by Prophet Muhammad ﷺ in the famous Hadith of Jibril, recorded in Sahih Muslim (8) and Sahih al-Bukhari (50), where the Angel Jibril (Gabriel), disguised as a traveller, questioned the Prophet ﷺ in front of his companions about Islam, Iman, and Ihsan. This hadith is considered one of the most important in all of Islamic theology (Aqeedah), as it defines the entire architecture of the religion in a single narration.

The six pillars are: belief in Allah, belief in the Angels, belief in the Books of Allah, belief in the Messengers, belief in the Last Day, and belief in Qadr (divine decree). Each is derived directly from the Qur’an and authentic Sunnah, and each carries specific theological implications that shape how a Muslim views existence itself. This guide explains all six in depth, with Qur’anic evidence, authentic hadith, and practical reflection for daily life. For the complementary set of obligations, see our guide to Salah (Prayer) in Islam, one of the Five Pillars of Islam that Iman gives its spiritual foundation.

Three Pillars in More Detail

Tawhid: The Oneness of Allah

Tawhid (توحيد) means affirming that Allah is One, without partner, in His lordship, in His sole right to be worshipped, and in His names and attributes. It was the message of every prophet:

وَمَآ أَرْسَلْنَا مِن قَبْلِكَ مِن رَّسُولٍ إِلَّا نُوحِىٓ إِلَيْهِ أَنَّهُۥ لَآ إِلَـٰهَ إِلَّآ أَنَا۠ فَٱعْبُدُونِ

“And We sent not before you any messenger except We revealed to him that, ‘There is no deity except Me, so worship Me.'” — Qur’an 21:25

Scholars commonly explain Tawhid under three headings:

• Rububiyyah (Lordship): Allah alone creates, owns and sustains everything. Even the Prophet’s opponents in Makkah admitted this: “If you asked them, ‘Who created the heavens and earth?’ they would surely say, ‘Allah'” (Qur’an 31:25). Admitting this alone is not enough without worship directed to Him.
• Uluhiyyah (Worship): all worship (prayer, dua, sacrifice, reliance) is for Allah alone. “And I did not create the jinn and mankind except to worship Me” (Qur’an 51:56). The Prophet ﷺ told Mu’adh that Allah’s right on His servants is “that they should worship Him (Alone) and should not worship any besides Him” (Sahih al-Bukhari 2856; Sahih Muslim 30).
• Asma wa Sifat (Names and Attributes): affirming the names and attributes Allah gives Himself, without likening Him to creation: “There is nothing like unto Him, and He is the Hearing, the Seeing” (Qur’an 42:11). See the 99 Names of Allah.

The opposite of Tawhid is shirk, associating partners with Allah: “Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills” (Qur’an 4:48).

Belief in Angels (Mala’ikah)

The Prophet ﷺ said: “The Angels were born out of light and the Jinns were born out of the spark of fire and Adam was born as he has been defined (in the Qur’an) for you” (Sahih Muslim 2996). Angels obey Allah completely: “they do not disobey Allah in what He commands them but do what they are commanded” (Qur’an 66:6). Allah “made the angels messengers having wings, two or three or four” (Qur’an 35:1).

• Iblis is not an angel: the Qur’an says “except for Iblees. He was of the jinn” (Qur’an 18:50).
• Recording angels: “He utters no word except that with him is an observer prepared [to record]” (Qur’an 50:18).
• Guardian angels: “For him are successive [angels] before and behind him who protect him by the decree of Allah” (Qur’an 13:11).
• In worship: on Fridays angels stand at the mosque door recording people in order of arrival (Sahih al-Bukhari 929), and the Prophet ﷺ told us to say “Ameen” after the imam finishes Al-Fatiha, as the angels say it (Sahih al-Bukhari 782).
• In the grave: two angels, named in hadith as Munkar and Nakir, question the deceased (Jami’ at-Tirmidhi 1071, graded hasan).

The Last Day (Yawm al-Qiyamah)

No one knows when the Hour will come: “Its knowledge is only with my Lord… It will not come upon you except unexpectedly” (Qur’an 7:187). The Prophet ﷺ named ten major signs before it: the smoke, the Dajjal, the beast, the sun rising from the west, the descent of ‘Isa son of Maryam, Gog and Magog, three landslides (in the east, the west and Arabia) and a fire that drives people to their gathering place (Sahih Muslim 2901).

• The gathering: “The people will be gathered barefooted, naked, and uncircumcised” (Sahih al-Bukhari 6527).
• The Scale (Mizan): “We place the scales of justice for the Day of Resurrection, so no soul will be treated unjustly at all” (Qur’an 21:47). Two phrases are “very heavy in the balance”: SubhanAllahil-‘Azim and SubhanAllahi wa bihamdihi (Sahih al-Bukhari 6406).
• The Bridge (Sirat): a bridge is set over Hell, and the believers cross it at different speeds, some “within the twinkling of an eye, like lightning, like wind” (Sahih Muslim 183).

فَمَن يَعْمَلْ مِثْقَالَ ذَرَّةٍ خَيْرًا يَرَهُۥ ۝ وَمَن يَعْمَلْ مِثْقَالَ ذَرَّةٍ شَرًّا يَرَهُۥ

“So whoever does an atom’s weight of good will see it, and whoever does an atom’s weight of evil will see it.” — Qur’an 99:7–8

Preparing for it: settle wrongs done to others now, before the Day “when there will be no money” (Sahih al-Bukhari 2449); do good deeds you can keep up, since the Prophet ﷺ said “the acts most pleasing to Allah are those which are done continuously, even if they are small” (Sahih Muslim 782); and “increase in remembrance of the severer of pleasures”, meaning death (Jami’ at-Tirmidhi 2307, graded hasan).
