The Relativity of Time: How Modern Physics Confirms the Qur'anic Perspective


For centuries, materialist philosophy asserted that time was an absolute, unchanging, and fixed constant of the universe. However, the theories of 20th-century physics—notably Albert Einstein’s Theory of Relativity—fundamentally proved that time is not absolute but is instead a flexible, interwoven dimension of space. This scientific conclusion directly affirms the profound perspective revealed in the Holy Qur'an: that time is ultimately a localized perception, created by God, who is Himself unfettered by its limitations.

I. Time as a Psychological Perception

In essence, time is not an external flow but an internal mechanism within the brain, used to compare one moment with another. When we recall a past event, that memory exists only in our mind in the present moment. The perception of "time elapsed" is merely the psychological process of comparing the memory (the past) with the conscious perception (the present). If our memory were erased, we would be incapable of perceiving the passing of time, living instead in a constant, single "moment."

The Qur’anic Example of Subjective Time

This relativity of perception is clearly illustrated in the story of the Companions of the Cave (Aṣḥāb al-Kahf). God kept this community of believers in a sleep-like state for centuries. When they finally awoke, their perception of the duration was dramatically different from the objective reality:

“So We sealed their ears with sleep in the cave for a number of years. Then We woke them up again so that we might see which of the two groups would better calculate the time they had stayed there.” (Surat al-Kahf, 18:11–12)

“That was the situation when We woke them up so they could question one another. One of them asked, ‘How long have you been here?’ They replied, ‘We have been here for a day or part of a day.’ They said, ‘Your Lord knows best how long you have been here…” (Surat al-Kahf, 18:19)

This example confirms that human experience of time is entirely subjective and based on a frame of reference that changes according to the perceiver. The fact that hours-long experiences in a dream can take place in a matter of seconds also demonstrates this psychological elasticity of time.

II. Scientific Proofs of Time’s Relativity

Albert Einstein demonstrated that time and space are woven into a single entity called spacetime, meaning that time is influenced by two physical factors: gravity and velocity.

A. The Effect of Gravity and Position

According to Einstein’s general theory of relativity, the presence of gravity slows the passage of time. The greater the gravitational pull, the slower time moves. The renowned physicist Stephen Hawking used the example of twins to illustrate this: If one twin lives atop a mountain (where gravity is slightly weaker) while the other stays at sea level, the mountain twin would age faster upon their reunion.

This theory has been confirmed with astonishing precision by atomic clock experiments:

  • Elevation Difference: Physicists at the National Institute of Standards and Technology (NIST) measured this effect at an extremely small scale. By comparing two sensitive atomic clocks positioned with a vertical difference of merely 33 centimeters (about two steps on a staircase), they confirmed that the higher clock ran faster. The difference is minuscule—approximately 90 billionths of a second over an average human lifetime—but the fact that time is not uniform, even across two steps, scientifically refutes the notion of absolute time.

B. The Effect of Velocity

The theory of relativity also predicts that the passage of time changes based on the observer’s speed. The faster an object moves, the slower time affects it, a phenomenon known as time dilation.

  • The Twin Paradox: If one twin takes a space voyage at a speed approaching the speed of light and then returns, the twin who stayed on Earth will be older. This effect is significant enough that the atomic clocks on Global Positioning System (GPS) satellites must be constantly corrected to account for both the effects of their velocity and their differing elevation from Earth.
  • Spacetime Warping: NASA experiments, such as the Gravity Probe B mission, have confirmed that large rotating bodies like the Earth literally warp and drag spacetime around them, demonstrating that the fabric of the universe is dynamic and pliable, not a static stage for absolute time.

III. The Qur’anic Definition of Time Scales

The scientific finding that time is variable and relative confirms the theological position of the Qur'an: that God is not confined to human measures of time. The Qur'an describes heavenly "Days" (Yawm) that are vastly longer than terrestrial days, emphasizing that time is a creation tailored for human beings:

  • “... A day with your Lord is equivalent to a thousand years in the way you count.” (Surat al-Hajj, 22:47)
  • “He directs the whole affair from heaven to earth. Then it will again ascend to Him on a Day whose length is a thousand years by the way you measure.” (Surat as-Sajda, 32:5)
  • “The angels and the Spirit ascend to Him in a day whose length is fifty thousand years.” (Surat al-Ma’arij, 70:4)

These differing time scales prove that time is a mutable perception depending on the dimension and the nature of the observer or the event. Furthermore, the Qur'an reveals that on the Day of Judgment, the perception of life on Earth will shrink to an insignificant moment:

“On the Day He calls you, you will respond by praising Him and think that you have only tarried a very short time.” (Surat al-Isra’, 17:52)

Conclusion: Time, Destiny, and the Timeless Creator

Modern science has conclusively demonstrated that time is a created, variable form of perception, effectively refuting the materialist claim of "absolute time and an eternal universe."

God, who created time and space out of nothing, is logically unfettered by them. For God, the past, present, and future—which are distinct to human perception—are encompassed within His single, timeless knowledge. This is the essence of the fact of Destiny: everything that happens is known by God outside of our temporal bounds.

The fact that these scientific truths, only verified by 20th-century physics, were revealed in the Qur'an 1400 years ago, serves as undeniable evidence that the text originates from the All-Knowing Creator:

“...They said, ‘Glory be to You! We have no knowledge except what You have taught us. You are the All-Knowing, the All-Wise.’” (Surat al-Baqara, 2:32)

The Prophet Muhammad’s (ﷺ) Leadership Skills: A Quranic and Sunnah Perspective

I. Introduction The leadership of Prophet Muhammad ( ﷺ ) stands as a pivotal subject within Islamic studies, revered by Muslims globally as the epitome of exemplary conduct and governance. Chosen by Allah as the final prophet and messenger, his life serves as a comprehensive model for humanity in all facets, including leadership across various domains. His leadership was instrumental in the profound social and moral transformation of the Arabian society during his time, ushering in an era marked by justice, equality, and spiritual enlightenment. The Holy Quran itself explicitly identifies Prophet Muhammad ( ﷺ ) as an "excellent pattern of behavior" ( اُسوہِ حسنہ ) for believers to emulate, as highlighted in Surah Al-Ahzab (33:21). This Quranic declaration underscores that his leadership is not merely a historical account but a divinely ordained standard for Muslims in their personal and collective lives, emphasizing its significance as a religious obligation and a path towar...

The Islamic Principles of Justice and Fairness: An In-Depth Analysis of "عدل" and "انصاف"

  1. The Foundational Principles of " عدل " and " انصاف " in Islam The concepts of " عدل " (Adl) and " انصاف " (Insaf) hold a paramount position in Islam. The Arabic term " عدل ," derived from the root 'a-d-l, carries a rich array of meanings that extend beyond a simple translation of justice. It signifies a state of equality, justness, straightness, and temperance, implying an inherent balance and equilibrium. This fundamental idea of balance permeates the Islamic understanding of justice, suggesting that any deviation from it constitutes a form of imbalance or transgression. Complementing " عدل " is the term " انصاف ," which embodies the notions of fairness, equity, and the act of giving to each individual what is rightfully theirs. While often used synonymously with " عدل " and another related term, " قسط " (Qist), " انصاف " often emphasizes the practical manifestation of justice...

The Brother Who Wasn't: How a Missing Word in Surah Shu'ara Reveals Islam's View of True Brotherhood

In Surah Ash-Shu'ara (The Poets), Allah takes us on a profound journey through the stories of the prophets. With remarkable consistency, He introduces each messenger with a phrase that resonates with intimacy and shared identity: "When their brother Nuh (AS) said to them..."  (26:106) "When their brother Hud (AS) said to them..."  (26:124) "When their brother Salih (AS) said to them..."  (26:142) "When their brother Lut (AS) said to them..."  (26:161) But then we reach Prophet Shu'ayb (AS): "When Shu'ayb (AS) said to them..."  (26:177) The words "their brother" are strikingly absent.  This omission isn't accidental – it's divine precision speaking volumes about the nature of true brotherhood. Why does Shu'ayb alone lose this title here, when elsewhere Allah  does  call him " their  brother Shu'ayb" (7:85)? The answer lies in a single, loaded word:  Aykah . The Two Names That Changed E...
