Islam Beliefs

Key Takeaways

Islam is built on six core beliefs (pillars of Iman) derived directly from the Hadith of Jibril, narrated in Sahih Muslim.

Belief in Tawheed — Allah’s absolute oneness — is the foundation of every other Islamic belief and the purpose of human creation.

Muslims must believe in all prophets without exception; rejecting even one prophet invalidates a person’s faith entirely.

Belief in the Last Day includes conviction in resurrection, the Day of Judgment, Paradise (Jannah), and Hellfire (Jahannam).

Belief in Qadar does not negate human responsibility; scholars distinguish between Allah’s knowledge and human free choice.

Islam beliefs form a precise theological framework that every Muslim — regardless of background, language, or level of scholarship — is required to know and hold. These are not abstract philosophical positions. They are the living foundation of Muslim identity, worship, and worldview.

The six pillars of Iman — belief in Allah, His angels, His revealed books, His messengers, the Last Day, and divine decree — constitute the complete structure of Islamic faith. Each pillar is established through direct Quranic evidence and authenticated prophetic tradition, and each carries specific theological implications that distinguish Islam from every other belief system.

What Are the Six Pillars of Iman in Islam?

The six pillars of Iman are: belief in Allah, belief in the angels, belief in the revealed books, belief in the prophets and messengers, belief in the Last Day, and belief in divine decree (Qadar) — both its good and its seemingly difficult aspects. These six are established in the famous Hadith of Jibril.

The Prophet Muhammad ﷺ said:

“Iman is that you believe in Allah, His angels, His books, His messengers, the Last Day, and that you believe in divine decree — both the good and the bad of it.” (Sahih Muslim 8)

This single hadith defines the entire creed of a Muslim. Classical scholars of Aqeedah — Islamic theology — treat this hadith as the foundational text from which all detailed creedal discussions flow.

At E Islamic Studies School, our Essential Islam Courses cover each pillar in structured depth with certified Islamic scholars, ensuring students build their belief on authentic Quran and Sunnah — not cultural assumptions or secondhand information.

1. Belief in Allah is The Foundation of All Islam Beliefs

Belief in Allah means affirming His absolute oneness (Tawheed) in three inseparable dimensions: His lordship over all creation (Tawheed ar-Rububiyyah), His exclusive right to be worshipped (Tawheed al-Uluhiyyah), and the perfection of His names and attributes (Tawheed al-Asma was-Sifat).

Allah ﷻ states in the Quran:

قُلْ هُوَ اللَّهُ أَحَدٌ
Qul huwa Allahu ahad
“Say: He is Allah, the One.” (Surah Al-Ikhlas 112:1)

This surah, according to the Prophet ﷺ, is equivalent in reward to one-third of the Quran — reflecting how central pure monotheism is to the entire religion.

The Three Categories of Tawheed

Category	Arabic Term	Meaning
Lordship	Tawheed ar-Rububiyyah	Allah alone creates, sustains, and controls all of existence
Worship	Tawheed al-Uluhiyyah	All acts of worship belong exclusively to Allah
Names & Attributes	Tawheed al-Asma was-Sifat	Allah’s names and attributes are affirmed as He described Himself — without distortion or denial

In our teaching experience, students who first encounter Tawheed often assume they already understand it simply because they say the Shahada.

What consistently surprises them is realizing that Tawheed al-Uluhiyyah — directing every act of worship, including supplication (du’a), fear, and hope, exclusively to Allah — is where most practical misunderstandings actually occur.

2. Belief in the Angels

Belief in the angels means affirming that Allah ﷻ created them from light (nur), that they are entirely obedient servants who never disobey their Lord, and that they carry out specific divine functions assigned to them. This is not symbolic belief — it is literal, theological conviction.

Among the angels with specific named roles:

Jibril (Gabriel) عليه السلام — carrier of divine revelation to the prophets
Mikail (Michael) عليه السلام — entrusted with provision and rain
Israfil عليه السلام — will blow the trumpet on the Day of Resurrection
Munkar and Nakir — question the deceased in the grave
Kiraman Katibin — the noble scribes who record every human deed

Allah ﷻ describes the angels’ absolute obedience:

لَّا يَعْصُونَ اللَّهَ مَا أَمَرَهُمْ وَيَفْعَلُونَ مَا يُؤْمَرُونَ
Laa ya’soona Allaha maa amarahum wa yaf’aloona maa yu’maroon
“They do not disobey Allah in what He commands them but do what they are commanded.” (Surah At-Tahrim 66:6)

3. Belief in the Revealed Books

Belief in the revealed books means affirming that Allah ﷻ sent down scriptures to various prophets as guidance for humanity.

Muslims believe in the Tawrah (Torah) given to Musa عليه السلام, the Zabur (Psalms) given to Dawud عليه السلام, the Injil (Gospel) given to ‘Isa عليه السلام, and the Quran given to Muhammad ﷺ.

A critical theological distinction applies here. Muslims believe in the original revealed forms of the earlier scriptures — not the current versions, which classical scholars and contemporary textual critics both confirm have undergone alteration (tahrif) over centuries.

The Quran, by contrast, is preserved in its original form. Allah ﷻ guaranteed its protection:

إِنَّا نَحْنُ نَزَّلْنَا الذِّكْرَ وَإِنَّا لَهُ لَحَافِظُونَ
Innaa nahnu nazzalnaa adh-dhikra wa innaa lahu lahaafithoon
“Indeed, it is We who sent down the message, and indeed, We will be its guardian.” (Surah Al-Hijr 15:9)

Belief in the Quran is not merely intellectual acceptance — it requires acting upon its rulings, seeking guidance in its verses, and studying its meanings through the methodology of Tafseer (Quranic exegesis).

4. Belief in the Prophets and Messengers

Belief in the prophets means affirming that Allah ﷻ sent messengers to every nation throughout human history, all carrying the same core message: worship Allah alone. Muslims must believe in all named prophets without exception — rejecting even one constitutes disbelief (kufr).

The Quran names 25 prophets explicitly. Among them: Adam, Ibrahim (Abraham), Musa (Moses), ‘Isa (Jesus), and Muhammad — all peace be upon them.

The Finality of Prophethood

Muhammad ﷺ is the Khatam an-Nabiyyin — the Seal of the Prophets. No prophet or messenger will come after him. This doctrine is established by explicit Quranic text:

مَّا كَانَ مُحَمَّدٌ أَبَا أَحَدٍ مِّن رِّجَالِكُمْ وَلَٰكِن رَّسُولَ اللَّهِ وَخَاتَمَ النَّبِيِّينَ
“Muhammad is not the father of any of your men, but he is the Messenger of Allah and the Seal of the Prophets.” (Surah Al-Ahzab 33:40)

Classical scholars, including Imam Ibn Kathir رحمه الله in his renowned Tafseer, explain this verse as an absolute and final theological statement.

5. Belief in the Last Day

Belief in the Last Day (Yawm al-Qiyamah) means affirming a complete sequence of events: death, the life in the grave (Barzakh), resurrection (Ba’th), the gathering (Hashr), the weighing of deeds (Mizan), the bridge over Hellfire (Sirat), and the final abode — either Jannah (Paradise) or Jahannam (Hellfire).

This belief is not merely about the afterlife as a destination. It fundamentally reorients a Muslim’s priorities, choices, and relationship with this world.

Classical scholars of Aqeedah treat detailed study of the Last Day as essential preparation for a purposeful Muslim life.

Key Events of the Last Day

Event	Arabic Term	Description
Death and the Grave	Al-Barzakh	The intermediate realm between death and resurrection
The Trumpet Blast	An-Nafkha	Israfil blows the trumpet — all are resurrected
The Gathering	Al-Hashr	All of humanity assembled for judgment
The Scales	Al-Mizan	Deeds weighed with absolute divine justice
The Bridge	As-Sirat	A bridge over Hellfire crossed according to one’s deeds
Final Destination	Jannah / Jahannam	Eternal Paradise or Hellfire

Belief in Divine Decree: Understanding Qadar in Islamic Belief

Belief in Qadar — divine decree — means affirming that Allah ﷻ has complete, pre-eternal knowledge of all things, that He recorded everything in the Preserved Tablet (Al-Lawh al-Mahfuz), and that nothing occurs in creation outside His will and wisdom. This applies to both what humans consider good and what they consider difficult.

Classical scholars structure Qadar into four levels:

‘Ilm — Allah’s eternal knowledge of all things
Kitabah — His writing of all decrees in Al-Lawh al-Mahfuz
Mashee’ah — His divine will, which encompasses all that exists
Khalq — His creation of all things, including human actions

Does Belief in Qadar Remove Human Responsibility?

No — and this is one of the most consistently misunderstood aspects of Islamic belief. Allah’s pre-eternal knowledge of a person’s choice does not cause that choice. A person chooses freely, and Allah knew — eternally — what they would choose.

The theological position of Ahl as-Sunnah wal-Jama’ah — mainstream Sunni Islam — holds that human beings possess genuine, real choice (iradah) and that they are accountable for it.

At E Islamic Studies School, our instructors have found that students typically require at least two or three dedicated sessions on Qadar before the distinction between divine foreknowledge and compulsion begins to feel genuinely clear — not just intellectually accepted, but internalized.

Frequently Asked Questions About Islam Beliefs

What is the difference between the pillars of Islam and the pillars of Iman?

The pillars of Islam refer to the five acts of worship — Shahada, Salah, Zakat, Sawm, and Hajj. The pillars of Iman refer to the six beliefs outlined in the Hadith of Jibril. Islam covers external practice; Iman covers internal conviction. Both are required for a complete, valid Muslim faith.

Is it possible to be Muslim without believing in all six pillars of Iman?

No. Classical scholars of Aqeedah are unanimous that all six pillars are obligatory. Rejecting any one of them — such as denying the existence of angels or disbelieving in divine decree — constitutes a departure from the fold of Islam according to the consensus (ijma’) of mainstream Sunni scholarship.

How does belief in Qadar relate to making du’a and taking practical steps?

Belief in Qadar does not contradict du’a or practical effort — both are themselves part of Allah’s decree. The Prophet ﷺ consistently made du’a and took practical precautions, teaching Muslims that reliance on Allah (tawakkul) is fulfilled through action, not by abandoning it. Ahl as-Sunnah affirms both divine will and human responsibility simultaneously.

Why do Muslims believe Jesus is a prophet but not divine?

Muslims affirm ‘Isa عليه السلام as one of Allah’s greatest messengers, born miraculously to Maryam عليها السلام, given the Injil, and still alive — to return before the Last Day. Islamic theology rejects his divinity because the Quran explicitly states Allah is one, without partner, son, or equal. This position is held by unanimous scholarly consensus.

How do new Muslims begin learning Islam beliefs properly?

New Muslims are encouraged to start with the six pillars of Iman and five pillars of Islam — these form the complete entry point to Islamic knowledge. Structured, one-on-one study with a qualified teacher is strongly recommended. E Islamic Studies School’s Learning Islam for New Converts course is specifically designed for this starting point, building belief correctly from the very first lesson.
