What are the Beliefs of Islam

People often assume Islam begins with rules—what to eat, how to pray, what to avoid. But for most new Muslims I’ve spoken to, belief comes first, quietly, before practice ever shows up. A single question lingers longer than expected, shaping everything that follows: who is God, really, and what does He ask of us?

At its core, Islamic belief rests on six interconnected convictions known as the pillars of iman: belief in Allah alone, His angels, His revealed books, His messengers, the Last Day, and divine decree. Together, they form a coherent worldview grounded in accountability, purpose, and complete submission to the Creator.

What Are The Beliefs of Islam?

The central beliefs of Islam, or the essential beliefs of Islam, are the six pillars of faith. ​In Islam, there are six fundamental beliefs that every Muslim must hold.

These major islam beliefs established in the famous “Hadith of Jibril” where Prophet Muhammad ﷺ said:

“It is to believe in Allah, His angels, His books, His messengers, the Last Day, and to believe in Divine Decree (Qadar).” (Narrated by Muslim)

In the following sections, we are going to present some key beliefs of Islam. They are as follows:

​1. Belief in Allah (The One God) is The Most Important Belief of Principle Beliefs of Islam

A new converter may ask, “What is the most foundational and essential belief of Islam?” The answer is the most essential of all Islam beliefs is Tawhid—the absolute Oneness of God.

Muslims must believe that Allah is the Unique, the Eternal, and the All-Powerful Creator who has no partners, no parents, and no children.

Consequently, this belief frees the human soul from subservience to any created being, connecting it directly to the Source of all existence.

Allah says in the Holy Quran:

 قُلْ هُوَ اللَّهُ أَحَدٌ ‎﴿١﴾‏ اللَّهُ الصَّمَدُ ‎﴿٢﴾‏ لَمْ يَلِدْ وَلَمْ يُولَدْ ‎﴿٣﴾‏ وَلَمْ يَكُن لَّهُ كُفُوًا أَحَدٌ ‎﴿٤﴾

“Say, ‘He is Allah, [who is] One, Allah, the Eternal Refuge. He neither begets nor is born, nor is there to Him any equivalent.'” (Surah Al-Ikhlas, 112:1-4). 

​2. Belief in the Angels is One of the Key Beliefs of Islam

One of the Muslim basic and religious beliefs is to believe in angels. ​Islam teaches that Allah created angels from light to carry out His commands.

Unlike humans, angels do not have free will. They do not commit sins and are constantly in service to the Divine Orders.

The rank and number of angels vary, from Gabriel (Jibril), who delivered the revelation, to the guardian angels. Muslims should believe in all kinds of angels. 

This belief reminds us that we are a part of a vast, unseen spiritual world. Believing in angels is a part of believing in the unseen world which is a part of true faith.

Allah says in the Holy Quran:

ءامَنَ ٱلرَّسُولُ بِمَآ أُنزِلَ إِلَيْهِ مِن رَّبِّهِۦ وَٱلْمُؤْمِنُونَ ۚ كُلٌّ ءَامَنَ بِٱللَّهِ وَمَلَـٰٓئِكَتِهِ 

“All of them have believed in Allah and His angels…” (Surah Al-Baqarah, 2:285).

​3. Belief in the Divine Scriptures is Among Basic Islam Beliefs

​Muslims should believe that Allah sent revelations to guide humanity and the Quran is the final and preserved Word of Allah. Believing in the previous books includes acknowledging the original messages which were sent to previous prophets.

These divine messages were revealed to honest messengers such as the Torah (sent to Moses) and the Gospel (sent to Jesus) . . .etc.

We should note that Muslim must believe these divine scriptures in their pure, unchanged forms.

Allah says in the Holy Quran: 

يَا أَيُّهَا الَّذِينَ آمَنُوا آمِنُوا بِاللَّهِ وَرَسُولِهِ وَالْكِتَابِ الَّذِي نَزَّلَ عَلَىٰ رَسُولِهِ وَالْكِتَابِ الَّذِي أَنزَلَ مِن قَبْلُ

“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.” (Surah An-Nisa, 4:136). 

​4. Belief in the Prophets and Messengers is One of the Main muslim Religious Beliefs

Someone may ask: What are the core beliefs of Islam? One of these ​core beliefs is to believe in the chain of prophethood. It is to believe in all the previous prophets and messengers 

Muslims must honor all prophets, starting from Adam, including Noah, Abraham, Moses, and Jesus, concluding with the Prophet Muhammad ﷺ. 

A true Muslim must believe that all these prophets were all human beings chosen by Allah to deliver His divine message which is to worship Allah alone.

Allah says in the Holy Quran:

وَلَقَدْ بَعَثْنَا فِي كُلِّ أُمَّةٍ رَّسُولًا أَنِ اعْبُدُوا اللَّهَ وَاجْتَنِبُوا الطَّاغُوتَ

“And We certainly sent into every nation a messenger, [saying], ‘Worship Allah and avoid Taghut (false deities).’” (Surah An-Nahl, 16:36).

5. Belief in the Day of Judgment is Another One of Major Islam Beliefs

​Islam provides a moral compass by teaching that life on Earth is a test. Every person will be held accountable for their intentions and actions on the Day of Resurrection. For more information; visit Salam Platform.

This belief ensures that justice is ultimately served. This belief encourages believers to live a life of integrity and compassion.

Allah says in the Holy Quran:

وَلَٰكِنَّ الْبِرَّ مَنْ آمَنَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَالْمَلَائِكَةِ وَالْكِتَابِ وَالنَّبِيِّينَ

“But righteous is [he who] believes in Allah, the Last Day, the angels, the Book, and the prophets…” (Surah Al-Baqarah, 2:177). 

​6. Belief in Divine Decree (Al-Qadar) is One of the Main Beliefs of Islam

​This belief teaches that Allah, in His infinite knowledge, knows everything that has happened and will happen.

While humans have the free will to choose between right and wrong, nothing occurs outside the ultimate will and wisdom of Allah . 

This belief provides a Muslim with feelings of comfort and peace (Sakinah) during times of hardship and troubles.

Allah says in the Holy Quran:

إِنَّا كُلَّ شَيْءٍ خَلَقْنَاهُ بِقَدَرٍ

“Indeed, all things We created with predestination.” (Surah Al-Qamar, 54:49).

What Are the Major Beliefs of Islam Concerning the Afterlife?

What do muslims believe? Muslims believe this worldly life is temporary—a test and preparation for eternal existence. After death, every human will be resurrected and held accountable before Allah for their beliefs and actions. 

The Quran describes the Day of Judgment (Yawm al-Qiyamah) in vivid detail. 

The earth will be shaken, the mountains will crumble, the sun will be darkened, and all humans from Adam to the last person born will stand before Allah. 

Each person’s book of deeds will be presented, and perfect justice will be established.

Those who believed in Allah’s oneness, followed His messengers, and lived righteously will enter Paradise (Jannah)—a realm of eternal bliss beyond human imagination. 

Those who rejected faith and persisted in wrongdoing will enter Hell (Jahannam)—a place of punishment and regret.

The Quran states: 

“And those who believed and did righteous deeds will be admitted to gardens beneath which rivers flow, abiding eternally therein by permission of their Lord…” (Quran 14:23)

This belief transforms how Muslims approach daily life. Knowing they’ll answer for every action, word, and even thought makes them conscious of Allah’s presence at all times. 

It motivates sacrifice, patience during hardship, and striving for justice even when worldly rewards seem distant.

The afterlife isn’t some vague spiritual concept in Islam—it’s described as more real than this temporary world. This life is the dream from which death awakens us to reality.

What Do Islam Believe Regarding Divine Decree and Human Free Will?

Among the essential beliefs of Islam is faith in Qadar—divine decree. Muslims believe that Allah has complete knowledge of all things past, present, and future. 

Nothing occurs in creation except by His will and permission, yet humans possess genuine free will and bear responsibility for their choices.

This concept challenges many Western philosophical frameworks that see divine sovereignty and human freedom as contradictory. 

In Islamic understanding, both truths coexist. Allah’s knowledge encompasses all possibilities, and His power controls all outcomes, yet humans make real choices and will be held accountable for them.

The Prophet Muhammad ﷺ taught: 

“Everything is determined by decree, even incapacity and ability.” 

This belief brings tremendous peace to the Muslim heart. When facing hardship, Muslims trust that nothing befalls them except what Allah has written for them. 

This doesn’t breed passivity but rather courage—knowing that ultimate outcomes rest with Allah frees believers to act righteously without being paralyzed by fear of failure.

At the same time, Islam firmly rejects fatalism. Humans cannot blame their sins on divine decree because Allah has given them reason, revelation, and genuine choice. The Day of Judgment would be meaningless if people had no real agency in their actions.

The Unique Beliefs of Islam That Define Muslim Identity

When we examine the core beliefs of Islam holistically, certain unique aspects emerge that distinguish Islamic faith from other religious traditions.

1. Islam demands intellectual conviction alongside spiritual experience

First, Islam demands intellectual conviction alongside spiritual experience. Muslims don’t believe “on faith alone” but are commanded to reflect, reason, and seek knowledge. The Quran repeatedly calls people to contemplate creation, use their intellect, and recognize Allah’s signs in the universe.

2. Islamic belief creates direct connection between the individual and Allah without intermediaries

Second, Islamic belief creates direct connection between the individual and Allah without intermediaries. Muslims don’t need priests, saints, or intercessors to reach their Creator. Every person can pray directly to Allah, seek His forgiveness, and build a personal relationship with Him.

3. The beliefs of Islam integrate the spiritual and material realms completely

Third, the beliefs of Islam integrate the spiritual and material realms completely. There’s no separation between “religious life” and “secular life” in Islamic thought. Belief in Allah should influence business ethics, family relationships, political engagement, and environmental stewardship equally.

4. Islam presents belief as both gift and responsibility

Fourth, Islam presents belief as both gift and responsibility. Faith (iman) isn’t static but increases with righteous deeds and decreases with sin. Muslims must actively cultivate and protect their beliefs through worship, learning, and conscious practice.

The Prophet Muhammad ﷺ described faith beautifully: 

“Faith is that you believe in Allah and His Angels and His Books and His Messengers and the Last Day, and that you believe in the Divine Decree, both its good and its evil.” (Sahih Muslim)

These beliefs aren’t mere theological abstractions. They create a comprehensive worldview that answers life’s deepest questions and provides a framework for navigating every human experience from birth to death and beyond.

Faith in angels, scriptures, and messengers situates human life within a larger unseen order governed by divine wisdom. Belief in the Day of Judgment and divine decree anchors ethics, patience, and accountability, ensuring that actions, intentions, and choices are never meaningless.
