Introduction

In a world where scepticism is rising and traditional beliefs are questioned, many people sincerely ask whether God exists and why Islam claims to offer the truth. Every worldview rests on foundational assumptions. The question is not whether we believe without absolute proof, but which worldview best explains reality, consciousness, morality, reason, and existence itself. This article explores these questions using reason, reflection, and evidence from both the natural world and human experience. Before exploring the evidence itself, we need to clarify what we mean by terms like 'proof', 'evidence', and 'belief', because these words are often used differently in science, philosophy, and religion.

What do we mean by evidence, proof, belief?

A general meaning of 'evidence' is information, facts, observations, or testimony that supports or opposes a claim. For example, footprints at the scene of a crime are evidence of a particular sole pattern that will match a particular shoe design that will either support the innocence or incriminate a suspect. In theology or that which relates to belief in a God, evidence can come in many forms such as philosophical arguments, historical testimony, religious experience, perceived design in nature, scripture, miracles and more.

A general meaning of 'proof' is evidence or reasoning sufficient to establish a conclusion. In law, especially criminal cases, proof is when there's sufficient evidence to conclude "beyond reasonable doubt". In other words, when evidence stacks up to a point where it's beyond reasonable to deny the conclusion. A question one may ask is at what point does enough evidence amount to proof? Certain proofs such as in mathematics are definite and provide logical certainty but others only give you a probabilistic outcome. Because humans are not all equal, each person may differ as to the point at which enough evidence becomes sufficient to constitute proof. As an example despite rational, physical, testimonial evidence, there are still people who deny it as proof for the earth being spherical and still hold to the idea that the earth is flat.

A general meaning of 'belief' is the acceptance of something as true, even without any proof. In fact, most human beliefs ranging from everyday assumptions to deep existential convictions are actually not rooted in any objective empirical evidence. Instead, most beliefs are rooted in cultural conditioning, cognitive shortcuts, and emotional needs. For many, this includes the belief in a God or a particular religion. However, this does not mean that there is no evidence.

Why people differ in accepting evidence

Due to cultural, emotional, cognitive, social, and personality differences, people can be presented with the same evidence yet reach very different conclusions. What one person sees as convincing proof, another may dismiss or reinterpret.

Islamic scholars and theologians explain that acceptance or rejection of belief in God is influenced not only by intellectual reasoning, but also by spiritual and psychological factors. Muslims believe that spiritual receptivity (hidayah) is a gift from God granted to those who sincerely seek truth with humility and openness. By contrast, pride, attachment to one's lifestyle, fear of change, or social pressures can sometimes prevent a person from accepting a message even if they recognise its strength intellectually.

For example, during the early years of Islam, several leaders of the Quraysh tribe strongly opposed Prophet Muhammad ﷺ despite acknowledging his honesty and integrity. Before prophethood, he was widely known as "Al-Amin" (the trustworthy), and even many of his enemies did not accuse him of lying. Historical reports suggest that some rejected his message because accepting it would have threatened their social status, tribal identity, political influence, and inherited traditions. This illustrates that rejecting a belief is not always simply about evidence alone; emotional, social, and personal factors often shape human judgement.

So, what is the evidence for the existence of God?

The Qur'an does not ask you to believe blindly — it asks you to think.

In the holy Qur'an, Allah says in Surah At-Tur (52:35-36) Sahih International: Allah presents a logical ultimatum regarding human and universal existence, asking:

"Or were they created by nothing? Or were they the creators [of themselves]? Or did they create the heavens and Earth? Rather, they are not certain."

In this verse, God uses a process of elimination to show that the universe didn't just happen by accident.

Imagine you walk into a room and see a beautifully built LEGO castle. The Qur'an asks you to think about how it got there by offering three logical options:

  • Did it come from nothing? (Did it just pop into existence out of thin air with no cause?)
  • Did it build itself? (Did the bricks decide to fly together and organize themselves into a castle?)
  • Did someone build it?

The Qur'an argues that the first two options are logically impossible. A "thing" cannot come from "nothing," and something that doesn't exist yet cannot create itself. By a process of elimination, the only logical answer left is that there must be a Creator who exists outside of the "LEGO set" and who put it all together.

It's essentially a "common sense" check: if every small thing we see (like a phone or a chair) has a maker, it stands to reason that the most complex thing we know — the entire universe — must have one too.

Cosmological and Natural Signs

In Surah Al-Baqarah (2:164): Allah points to the precision of nature as proof of a Designer, detailing phenomena such as:

"Indeed, in the creation of the heavens and the earth, and the alternation of the night and the day... and [in] the rain that Allah sends down from the sky, reviving thereby the earth after its lifelessness... are signs for a people who use reason."

Surah Al-Anbiya (21:30): Highlights the interconnectedness and expansion of the universe, implying that the universe had a beginning:

"Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe?"

These verses invite us to reflect on the order and precision of the universe. Think of the universe like a high-end Swiss watch or a perfectly coded computer program. The Qur'an is saying: "Look at how smoothly everything runs; that's not a coincidence."

Here's the breakdown:

  • The "Goldilocks" Effect: The Qur'an points out things like the sun rising every day, the moon's phases, and the rain falling to grow food. These aren't just random events; they happen in a perfect "loop" that allows us to stay alive. If the earth were a tiny bit closer to the sun, we'd burn; a tiny bit further, we'd freeze.
  • The Signature of the Artist: Just like you can recognize a painter by their brushstrokes, the Qur'an says you can recognize God by looking at "signs" in nature. The fact that the universe follows strict laws of physics (instead of being total chaos) suggests there is a "Lawgiver" who set the rules. Who created the gravitational, electromagnetic, weak and strong nuclear forces?
  • Complexity from Simplicity: It mentions things like "every living thing being made from water." The Qur'an is asking: How could such diverse, complex life (birds, trees, humans) all come from the same basic building blocks unless there was a master design behind it? Just like a Picasso painting that no one would assume arose from random events.

The Bottom Line: If you saw a giant, complex machine working perfectly for billions of years without crashing, you wouldn't assume it was a fluke — you'd assume someone very smart designed it and keeps it running.

The Human Conscience and Soul

In Surah Al-Qiyamah (75:2-15): The Qur'an points to the human conscience, self-reproach, and sense of morality as an internal proof of accountability and a higher power.

In Surah Ar-Rum (30:30): Allah mentions Fitrah — the idea that every human is born with an innate, natural disposition to recognize their Creator:

"So direct your face toward the religion, inclining to truth. [Adhere to] the fitrah of Allah upon which He has created mankind."

In layman's terms, this argument is about your "internal compass." It suggests that proof of God isn't just out there in the stars, but also inside your own heart and mind.

Here's how it breaks down:

  • The "Factory Setting" (Fitrah): Imagine buying a new phone that already has a "Home" button programmed into it. The Qur'an says humans have a "factory setting" called Fitrah. It's that deep, gut feeling most people have that there is something bigger than us. Even if someone has never read a religious book, they often feel a natural pull toward a Creator, especially when they see a sunset or face a big life challenge.
  • The Moral Compass: Why do we feel guilty when we lie, or feel good when we help someone? The Qur'an points to the human conscience (the Nafs). If we were just "meat computers" evolved only to survive, we wouldn't necessarily care about "right" or "wrong" — we'd only care about "winning." The fact that we have a built-in sense of justice and morality suggests someone "installed" that software in us. While evolutionary theories may explain how moral behaviour developed, many philosophers argue they do not fully explain why humans experience moral obligations as objectively binding.
  • The Search for Meaning: Animals are happy as long as they have food and sleep. Humans, however, always ask, "Why am I here?" The Qur'an argues that this unique hunger for purpose is proof that we weren't just a biological accident; we were made for a reason.

The Bottom Line: You don't just find God by looking through a telescope; you find Him by looking at why you have a soul, a conscience, and a natural instinct to seek the truth. The idea that children are "born believers" (fitrah) is corroborated by the Cognition, Religion, and Theology Project led by Dr. Justin Barrett at Oxford University, and the "intuitive theism" studies by Dr. Deborah Kelemen. These studies suggest human children are predisposed to believe in a higher power and in purpose in nature.

But why the Islamic God (Allah)?

To understand why millions of people accept Islam as the correct religion, consider these foundational arguments.

1. Monotheism & Pure Logic

  • One Creator: Islam rejects partners, sons, or intermediaries to God. It posits one supreme, eternal Creator who is entirely distinct from His creation.
  • Intellectual Appeal: The theology avoids complex paradoxes (like a God that dies or is divided into parts). It matches the human intuition that an ordered universe has a single Designer.

2. The Preservation of the Qur'an

  • Unchanged Text: Muslims believe the Qur'an has been preserved with an unparalleled degree of textual stability through both oral and written transmission for over 1,400 years.
  • Oral & Written Transmission: It has been memorized letter-for-letter in its various modes of recitation by millions of people across every generation, preventing alterations, deletions, or regional variations.

3. Clear Purpose & Universal Equality

  • Direct Relationship: You pray directly to God without needing a priest, saint, or confession booth.
  • Total Equality: Islam explicitly rejects racism, nationalism, and tribalism. True honour is based solely on a person's inner righteousness and character.
  • Cohesive Worldview: It provides a complete manual for life, perfectly balancing spiritual peace, mental clarity, and practical laws for a just society.

4. Continuity of All Prophets

  • One Single Message: Islam is not a "new" 7th-century religion. It is the final, corrected version of the same message brought by Adam, Noah, Abraham, Moses, and Jesus.
  • Honouring the Past: A Muslim must love and believe in all previous true prophets. Accepting Islam is viewed as completing — not abandoning — your belief in God's prior messengers.

5. Prophet Muhammad's ﷺ life and character

  • Prophet Muhammad ﷺ lived a life that is difficult to explain without acknowledging his sincerity and truthfulness. He began as a man known universally as "Al-Amin" — the most trustworthy — long before claiming prophethood. When revelation came, he gained no wealth, power, or privilege; instead, he faced persecution, exile, and loss, yet remained unwavering in his message. His teachings transformed one of the most divided societies on earth into a civilisation built on justice, literacy, charity, and equality. Unlike founders of other movements, every detail of his life — how he spoke, ate, prayed, forgave, and led — is preserved with unmatched historical clarity. His character, consistency, and impact make it difficult to see him as an imposter or a deluded man; rather, they point to someone genuinely guided by God.

Why did God create us?

Once we establish that God exists and that Islam presents a compelling case as His final message, the next natural question is: why did God create us in the first place?

Everyone would acknowledge that our body parts, such as our eyes, ears, brains, and hearts, have a purpose. Wouldn't it then make sense that the individual, as a whole, also has a purpose? God, the All Wise, did not create us to simply wander aimlessly or to only fulfil our basic instincts and desires. Rather, God describes this life as a test. Every person is being tested as to who will choose to acknowledge God and follow His guidance.

God says:

"Indeed, We (God) created man ... in order to test him; and we gave him hearing and vision. Indeed, We (God) showed him the way, whether he be grateful or ungrateful."Qur'an 76:2-3

For many, the underlying issue is not really about believing in God, but about the implications of believing in Him. It would mean being held to account and judged for one's actions, which may be inconvenient for the lives they want to lead. Therefore, the test in this life involves following and humbling ourselves before God in preference to our own desires, pride, and ego.

Why does God need to test us?

God is not in need of anything — He does not need to create anything and does not need to test anyone. He does not benefit from our belief and is not affected by our disbelief. Rather, it is part of His infinite wisdom that He created us and gave us the opportunity to know Him. God knows the future — the point is, for us to live through and experience our lives and make our own choices.

Do we really have a choice?

The fact that God knows our choices does not make it any less voluntary. Although God wants people to believe in Him, He does not force anyone. If God willed, He could guide all of humankind, as He has power over everything. But in His Wisdom, He has created us with the ability to choose and made us accountable for our choices. God is not necessarily pleased with everything that He allows to occur.

Why doesn't God just reveal himself?

If God revealed Himself openly, belief would no longer be a choice — it would be an unavoidable reaction. The test of sincerity would disappear.

In God's wisdom, He has chosen to make Himself known through His signs. This is part of the test of this life. He has made it our responsibility to use the abilities He has given us to acknowledge Him. This means that only those who are sincere, humble, and reflect deeply will recognise and believe in Him.

Why does God punish people?

No one can disagree with the concept of punishment, which is necessary for justice. God has created us with the ability to choose how we want to live, and in turn, be accountable. Those who sincerely strive to obey God will earn God's mercy and enter paradise. But those who are careless about their purpose in life and deny God have ultimately made their own choice and will be held to account. No one can blame God. God did not create people to punish them — rather, He intends ease and mercy for them. The fact that God knows our choices does not make our actions any less voluntary and does not absolve us from responsibility.

Islam is a practical religion that encourages a balance between hope in God's mercy and fear of His punishment — both of which are required to lead a positive and humble life. God is the Most Merciful but also the Most Just. If there were no day of Judgement, it would contradict the perfect justice of God, and life would be unfair.

Conclusion

Are we only here for 80 or so years, and that's it? Or is there more to life? Are we just advanced apes with no ultimate purpose? Are we material beings with only physical needs, or do we also have spiritual needs?

No argument forces belief mathematically. Rather, Islam argues that the cumulative weight of evidence points toward God and revelation. For those who are genuine and still undecided about God, our advice is to sincerely ask for the following: "GOD, IF YOU EXIST, PLEASE GUIDE ME." You might be surprised by the results!

If you are searching for truth, keep your heart open and continue exploring — Islam welcomes sincere seekers.
