Short Summary
Iman means true, sincere belief in the heart. Islam teaches that Iman has six pillars: belief in ALLAH, His angels, His revealed books, His messengers, the Last Day, and divine decree (Qadar). These six pillars are established in the Quran and confirmed in an authentic hadith of Prophet Muhammad ﷺ (Peace Be Upon Him). Every Muslim holds all six.
Introduction
In the previous lesson, you learned that ALLAH created us to worship Him. But worship begins with what you believe. Before the outward acts come the inward convictions.
Iman (إيمان) is belief — true, sincere, living faith in the heart. Islam teaches that Iman is not only words on the tongue or a set of inherited customs. It is a deep conviction that shapes how you understand the world, how you make decisions, and what you live for.
This lesson introduces the six pillars of Iman — the essential beliefs that every Muslim holds — and explains each one clearly, with evidence from the Quran and the authenticated teachings of Prophet Muhammad ﷺ (Peace Be Upon Him).
What Does Iman Mean?
The Arabic word Iman (إيمان) comes from the root a-m-n (أ م ن). This root carries the meanings of safety, trust, and security. Iman means faith — but a specific kind: a sincere conviction held in the heart, affirmed by the tongue, and lived through action.
In Islamic teaching, Iman is not merely claiming to believe. It is a living faith that can grow stronger through worship, learning, and obedience — and can weaken through neglect and sin.
You have already encountered the three dimensions of a Muslim's inner and outer life:
- Islam — outward submission and practice
- Iman — inner belief and faith
- Ihsan — worshipping ALLAH with full awareness and sincere excellence
This lesson focuses on Iman — specifically, what a Muslim believes.
The Evidence for the Six Pillars of Iman
The six pillars are not a list invented by scholars. They come directly from the Quran and from an authenticated hadith of Prophet Muhammad ﷺ (Peace Be Upon Him).
From the Quran
Three verses in the Quran establish the pillars of Iman together:
وَلَٰكِنَّ ٱلْبِرَّ مَنْ ءَامَنَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ وَٱلْمَلَٰٓئِكَةِ وَٱلْكِتَٰبِ وَٱلنَّبِيِّۦنَ
“But righteousness is in one who believes in ALLAH, the Last Day, the angels, the Book, and the prophets.”
ءَامَنَ ٱلرَّسُولُ بِمَآ أُنزِلَ إِلَيْهِ مِن رَّبِّهِۦ وَٱلْمُؤْمِنُونَ ۚ كُلٌّ ءَامَنَ بِٱللَّهِ وَمَلَٰٓئِكَتِهِۦ وَكُتُبِهِۦ وَرُسُلِهِۦ لَا نُفَرِّقُ بَيْنَ أَحَدٍ مِّن رُّسُلِهِۦ
“The Messenger has believed in what was revealed to him from his Lord, and so have the believers. All of them have believed in ALLAH, His angels, His books, and His messengers, saying: 'We make no distinction between any of His messengers.'”
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ ءَامِنُوا۟ بِٱللَّهِ وَرَسُولِهِۦ وَٱلْكِتَٰبِ ٱلَّذِى نَزَّلَ عَلَىٰ رَسُولِهِۦ وَٱلْكِتَٰبِ ٱلَّذِىٓ أَنزَلَ مِن قَبْلُ ۚ وَمَن يَكْفُرْ بِٱللَّهِ وَمَلَٰٓئِكَتِهِۦ وَكُتُبِهِۦ وَرُسُلِهِۦ وَٱلْيَوْمِ ٱلْءَاخِرِ فَقَدْ ضَلَّ ضَلَٰلًا بَعِيدًا
“O you who have believed, believe in ALLAH and His Messenger and the Book that He sent down upon His Messenger and the Scripture which He sent down before. And whoever disbelieves in ALLAH, His angels, His books, His messengers, and the Last Day has indeed gone far astray.”
These three verses together name five of the six pillars. The sixth — belief in divine decree (Qadar) — is explicitly confirmed in the Hadith of Jibril.
From the Authenticated Sunnah
The narration known as the Hadith of Jibril is one of the most important hadith in all of Islam. The Angel Jibril (Gabriel) (Peace Be Upon Him) came to Prophet Muhammad ﷺ (Peace Be Upon Him) in the form of a man and asked him three questions: about Islam, about Iman, and about Ihsan.
When asked "What is Iman?", the Prophet ﷺ answered:
Iman is that you believe in ALLAH, His angels, His books, His messengers, the Last Day, and that you believe in divine decree — its good and its bad.
This narration gives us the explicit, complete list of all six pillars of Iman in one sentence. It is graded Sahih (authentic).
Pillar 1: Belief in ALLAH
The first and greatest pillar is belief in ALLAH — the One God, the Creator of all that exists.
Belief in ALLAH includes four essential matters:
1. ALLAH exists. He is real. He is not a symbol of nature, a product of the human imagination, or a philosophical concept. ALLAH is the Living, Self-Sustaining Creator.
2. ALLAH is One (Tawheed). He has no partner, no equal, no child, and no one shares in His divinity or His right to be worshipped.
3. ALLAH has the most beautiful names and attributes. He describes Himself in the Quran — He is Ar-Rahman (the Most Merciful), Al-Alim (the All-Knowing), Al-Qadir (the All-Powerful), Al-Hayy (the Ever-Living), and many others. A Muslim believes in these names and attributes as ALLAH has described Himself, without distorting or denying their meaning.
4. Worship belongs to ALLAH alone. Only ALLAH deserves worship. This is the meaning of the Shahadah: La ilaha illa ALLAH — there is no god worthy of worship except ALLAH.
Belief in ALLAH is the root from which every other pillar of Iman grows. All five remaining pillars flow from knowing and trusting ALLAH.
Pillar 2: Belief in the Angels
The second pillar is belief in the angels (mala'ikah, الملائكة).
Angels are real created beings — not symbols or metaphors. ALLAH created them from light. They do not eat, sleep, or have physical needs. They do not disobey ALLAH. Their entire existence is devoted to carrying out His commands.
The Quran describes the angels directly:
ٱلْحَمْدُ لِلَّهِ فَاطِرِ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ جَاعِلِ ٱلْمَلَٰٓئِكَةِ رُسُلًا أُو۟لِىٓ أَجْنِحَةٍ مَّثْنَىٰ وَثُلَٰثَ وَرُبَٰعَ
“All praise is for ALLAH, Creator of the heavens and the earth, who made the angels as messengers having wings — two, three, or four.”
Among the angels mentioned in the Quran and authentic Sunnah:
- Jibril (Gabriel) (Peace Be Upon Him) — the angel of revelation, who delivered ALLAH's words to the prophets.
- Mikail (Michael) (Peace Be Upon Him) — assigned to rain and provision by ALLAH's command.
- Israfil — who will blow the trumpet on the Day of Judgment by ALLAH's command.
- The angel of death (Malak al-Mawt) — assigned by ALLAH to take souls at their appointed time.
- The recording angels (Kiraman Katibin) — assigned to record every person's deeds.
- Munkar and Nakir — the angels who question the soul in the grave.
A Muslim does not worship angels, pray to them, or treat them as partners with ALLAH. They are honored as ALLAH's obedient creation — but worship belongs to ALLAH alone.
Pillar 3: Belief in the Revealed Books
The third pillar is belief in the books ALLAH revealed to His messengers.
ALLAH sent guidance to human beings through revelation. He revealed scriptures to specific prophets as guidance for their communities and their times.
The scriptures mentioned in the Quran include:
| Scripture | Arabic Name | Prophet Who Received It |
|---|---|---|
| Scrolls | Suhuf (صحف) | Ibrahim (Abraham) (Peace Be Upon Him) |
| Torah | Tawrah (التوراة) | Musa (Moses) (Peace Be Upon Him) |
| Psalms | Zabur (الزبور) | Dawud (David) (Peace Be Upon Him) |
| Gospel | Injil (الإنجيل) | Isa (Jesus) (Peace Be Upon Him) |
| Quran | Quran (القرآن) | Muhammad ﷺ (Peace Be Upon Him) |
A Muslim believes that all of these were originally revealed by ALLAH as true guidance. However, the Quran teaches that the earlier scriptures were not fully preserved — they were changed, altered, or lost over time. The Quran alone is the final, preserved, and unchanged revelation. ALLAH guarantees its protection.
A Note on the Quran's Preservation
The Quran has been memorized in its complete form by millions of Muslims across every generation since its revelation — a chain of oral transmission that continues today. This level of preservation is unique among scriptures.
A Muslim respects all the earlier prophets and the original guidance they received from ALLAH. But the Quran and the authentic Sunnah of Prophet Muhammad ﷺ (Peace Be Upon Him) are the complete and preserved final guidance that Muslims follow today.
Pillar 4: Belief in the Messengers
The fourth pillar is belief in all of ALLAH's messengers — every one of them.
ALLAH sent prophets and messengers to every nation throughout human history. Their message was always the same: worship ALLAH alone and stay away from all false objects of worship.
وَلَقَدْ بَعَثْنَا فِى كُلِّ أُمَّةٍ رَّسُولًا أَنِ ٱعْبُدُوا۟ ٱللَّهَ وَٱجْتَنِبُوا۟ ٱلطَّٰغُوتَ
“And We certainly sent into every nation a messenger, saying: Worship ALLAH and avoid false objects of worship.”
The Quran mentions 25 prophets by name, including Adam, Idris (Enoch), Nuh (Noah), Ibrahim (Abraham), Ismail (Ishmael), Ishaq (Isaac), Yaqub (Jacob), Yusuf (Joseph), Musa (Moses), Harun (Aaron), Dawud (David), Sulaiman (Solomon), Isa (Jesus), and others (Peace Be Upon Them All).
The final prophet and messenger was Muhammad ﷺ (Peace Be Upon Him). After him, no new prophet will come. His message is complete, and it is for all of humanity until the Last Day.
A Muslim does not rank the prophets against each other or show disrespect to any of them. Belief in all the messengers is required. Rejecting any prophet is rejecting what ALLAH has commanded.
Pillar 5: Belief in the Last Day
The fifth pillar is belief in the Last Day (Yawm al-Akhirah, يوم الآخرة) — the Day of Judgment and Resurrection.
Islam teaches that this world will end. Every human being who has ever lived will be raised and will stand before ALLAH. Every deed — down to the smallest — will be weighed and accounted for.
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.”
The Last Day includes a sequence of stages, each established in the Quran and the authentic Sunnah:
- Death — every soul departs from this world at its appointed time.
- The Intermediate State (Barzakh, البرزخ) — a period of waiting between death and resurrection.
- The Resurrection (Ba'th, البعث) — all souls raised and gathered before ALLAH.
- The Reckoning (Hisab, الحساب) — every deed weighed on the Scale of Justice.
- The Bridge (Sirat, الصراط) — crossed according to deeds and ALLAH's mercy.
- Paradise (Jannah, الجنة) — for those whom ALLAH accepts through His mercy and their sincere faith and deeds.
- Hellfire (Jahannam, جهنم) — the consequence for those who died rejecting ALLAH without repentance.
Belief in the Last Day gives this life real weight. Nothing is wasted. Every moment of patience, kindness, and sincere obedience is recorded. Every sin can be repented from before death arrives. ALLAH is the Most Merciful — and He is also the Just Judge.
Pillar 6: Belief in Divine Decree (Qadar)
The sixth pillar is belief in Qadar (القدر) — divine decree, sometimes translated as predestination or fate.
This pillar means that ALLAH knows all things, that everything happens according to His knowledge and will, and that He is the Creator of all that exists.
إِنَّا كُلَّ شَىْءٍ خَلَقْنَٰهُ بِقَدَرٍ
“Indeed, We have created all things according to a precise measure.”
مَآ أَصَابَ مِن مُّصِيبَةٍ فِى ٱلْأَرْضِ وَلَا فِىٓ أَنفُسِكُمْ إِلَّا فِى كِتَٰبٍ مِّن قَبْلِ أَن نَّبْرَأَهَآ ۚ إِنَّ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرٌ
“No disaster strikes upon the earth or among yourselves except that it is in a register before We bring it into being — indeed, that is easy for ALLAH.”
The Beginner Foundation for Qadar
For beginners, four truths about Qadar form the safe, clear foundation:
1. ALLAH knows everything (Ilm). ALLAH's knowledge is complete, perfect, and eternal. He knows everything that has happened, is happening, and will happen — before it comes into being. Nothing is hidden from Him and nothing surprises Him.
2. ALLAH recorded everything (Kitabah). Before creation, ALLAH wrote all of this in the Preserved Tablet (Al-Lawh al-Mahfuz, اللوح المحفوظ). Nothing was left unwritten.
3. Nothing happens outside ALLAH's will (Mashi'ah). Whatever ALLAH wills comes into being. Whatever He does not will does not come into being. There is no power or event outside His authority.
4. ALLAH created all things (Khalq). ALLAH is the Creator of everything that exists — including the actions and choices of His creation.
Human Choice and Responsibility
Belief in Qadar does not remove human responsibility. This is an important point for every beginner.
ALLAH gave human beings genuine will, reason, and the ability to choose. When a person commits a sin or chooses to do good, they are making a real choice. ALLAH knew what they would choose — but His knowledge did not force their choice.
Do Not Use Qadar as an Excuse
Do not use Qadar to excuse wrongdoing. The Quran and the authentic Sunnah are clear: you are responsible for your choices, and you will be questioned for them on the Day of Judgment. Saying "ALLAH decreed it" after committing a sin is not an accepted justification in Islam.
Qadar is a topic of great depth, and advanced theological discussions about it exist. At this beginner level, hold these four truths clearly and build your understanding from there. Do not rush into complex debates before the foundation is firm.
What Beginners Should Avoid Misunderstanding
Iman is not just saying words. Iman begins in the heart. Words without belief have no value. Belief without sincere effort to live by it is incomplete. The Shahadah is the verbal confirmation of what the heart must genuinely hold.
Qadar does not mean ALLAH forced you into your choices. ALLAH knowing what you will choose is not the same as ALLAH forcing you to choose it. You are a real agent making real choices. You carry real responsibility for them. Using Qadar as an excuse for wrongdoing is a misunderstanding — not a teaching of Islam.
Muslims do not worship angels or prophets. Angels and prophets are honored, respected, and loved. But only ALLAH is worshipped. Directing acts of worship toward any created being — however noble — violates the core of Tawheed.
The earlier scriptures are not the same as the Quran. Muslims believe the original revelations to earlier prophets were true and from ALLAH. Those scriptures, however, were not fully preserved. The Quran is the complete, preserved, and final word of ALLAH. Muslims follow the Quran and the authentic Sunnah — not the altered earlier scriptures — as their guidance.
All six pillars are required — not five, not four. Iman is not a set of optional beliefs. The Quran commands belief in all six. Rejecting even one pillar is a serious matter in Islamic teaching.
Common Questions
Do I need to know the name of every angel and prophet? No. At the beginner level, what is required is belief in angels and prophets as categories — that they exist, that ALLAH created and sent them. Learning the specific names, stories, and roles of individual angels and prophets deepens your knowledge and Iman over time, but it is not required for the foundational belief.
What happened to the original Torah and Gospel? Muslims believe ALLAH truly revealed the Torah to Musa (Moses) (Peace Be Upon Him) and the Injil (Gospel) to Isa (Jesus) (Peace Be Upon Him). The Quran affirms this. Over centuries, however, those scriptures were not preserved in their original form — translations, omissions, and human changes altered them. Muslims do not disrespect those prophets or deny that they received revelation. But the current Bible is not the same as the original revelation, which is why Muslims follow the Quran and the authentic Sunnah today.
Does Qadar mean fatalism — that nothing I do matters? No. Fatalism says your choices are irrelevant because everything is already fixed. Islam does not teach this. Qadar means ALLAH knows and controls all things. You are a genuine agent with genuine choices and genuine consequences. Make effort. Make du'a. Take the right means. Trust ALLAH with the result. Your accountability on the Day of Judgment is real.
Can Iman increase and decrease? Yes. Iman can increase through acts of worship, seeking knowledge, remembering ALLAH, and doing good deeds. It can weaken through sin, heedlessness, and neglect. This is why regular prayer, Quranic recitation, seeking knowledge, and avoiding sin are all emphasized in Islam — they protect and strengthen the Iman in your heart.
