Allah is the Light of the heavens and the earth

Allah is the Light of the heavens and the earth. So what does this profound declaration mean?

Light allows us to see things as they truly are. In the dark, a blanket can look like a monster; but light reveals the truth.

Without Allah’s light (the faith and conviction He places in hearts), even if we observe the universe, we can never grasp its true nature or its worth.

Allah is the one and only source that makes it possible to understand what the heavens and the earth truly are.

Yet how can human beings, who are limited, grasp anything of Allah’s infinite reality? The rest of the ayah explains this as follows:

Notice the distancing manner of expression here: the words “example/likeness” (‎مَثَل‎) and “like” (‎ك‎) form a double distancing, emphasizing that the comparison is no more than a remote approximation compared to the reality.

What the human mind can conceptually encompass falls infinitely short beside the reality of Allah.

The image unfolds before our eyes layer by layer.

‎مِشۡكَوٰة‎ is an arched niche carved into the wall, where lamps used to be placed in homes; its curved inner surface would reflect the light throughout the room. ‎فِيهَا‎ (within it) there is a ‎مِصۡبَاحٌ‎, that is, “a lamp.”

This lamp is inside a ‎زُجَاجَة‎, that is, a transparent glass.

The glass itself is ‎كَأَنَّهَا كَوۡكَبٌ دُرِّىٌّ‎, “as if it were a brilliantly shining star.” The word ‎دُرِّىٌّ‎ here expresses an extreme, intense brightness. When light strikes this clear glass at certain angles, it creates a star-like effect, with rays spreading out from a single bright point, just like a gleaming pearl.

Its fuel comes from ‎شَجَرَةٍ مُّبَٰرَكَةٍ زَيۡتُونَةٍ‎, “a blessed olive tree.”

The word ‎مُبَٰرَكَة‎ expresses something that goes beyond normal limits and produces far more good than expected. But this is not just any olive tree;

This expression describes a tree standing on its own, not within a forest. If it stood on the eastern edge of a forest, only its western side would receive full sunlight; if it were on the western edge, only its eastern side would benefit from it.

But a single tree in an open field receives light from the rising of the sun until its setting and, just like those matchless olive trees of Palestine and Syria, produces the purest, finest-quality oil.

This oil is so pure and of such quality that

Just like gasoline, which ignites easily as if chasing after the flame, this oil is ready to burn instantly. Even before any burning takes place, it has a brightness of its own.

Then comes that climactic point:

Now, let us understand what this unique metaphor teaches us.

The hollow in the wall resembles the human rib cage, which has a similarly curved shape. The lamp inside it represents the heart. What surrounds that heart is the transparent glass. And the transparent glass is the state in which every human being comes into the world: with a pure and natural disposition (fitrah), free of prejudice and corruption.

In the depths of the heart there is something of extraordinary purity, belonging neither to the east nor to the west: the soul.

Just as Allah describes Himself as ‎نُور‎ (light), the soul too is a being created from light. This soul is potential light; that is, a radiance waiting to be revealed and a fuel ready to be kindled.

The glass surrounding this inner light remains spotless and transparent in its natural state, so that the light within can shine outward and the light outside can penetrate within. This symbolizes the deep connection between inner reality and outer reality.

But there is an important point here: the human body has certain needs, such as eating, clothing, shelter and desire, all of which stem from our earthly nature. We were created from earth; therefore our physical needs can only be met by things that also come from the earth.

In the same way, the soul, created from light, has a hunger of its own. When the soul is hungry, only light can satisfy it.

No worldly pleasure can fill that spiritual void (the sense of emptiness that people describe as the absence of something vital within them).

The pure oil is ready, the lamp has been prepared; so what sets it in motion? Fire; that is, revelation, the Qur’an and guidance from Allah.

When the light within a person finally meets the light of divine revelation, what emerges is ‎نُّورٌ عَلَىٰ نُورٍ‎, “light upon light”: the potential light within merging with the light of revelation that comes from outside.

The software has been installed; revelation is the activation key that makes it fully functional and valid.

But there is a critical condition for this union: the glass of the lamp must remain clean.

Every sin, every act stemming from greed, envy, anger or disobedience, soils that glass. When enough darkness builds up, two disasters happen at once: the goodness trapped inside can no longer shine outward and is smothered, and the light of revelation from outside cannot get through that layer of grime to reach the heart.

The light strikes the stained glass and bounces back, again and again.

Consider this fact: the Quraysh of Makkah knew Arabic at a level we can never reach.

They personally witnessed the revelation of the Qur’an, heard the character of the Prophet (peace be upon him) described in the most vivid detail, and saw his noble conduct with their own eyes. They experienced the circumstances and context of the time in which the Qur’an was revealed better than any generation after them ever could.

Even so, many of them still rejected it. Why? Intellectually, perhaps they accepted its truth; but spiritually their hearts were covered with grime. So much so that the light could not seep in.

This is why someone whose Arabic is limited may suddenly cry out while reading the Qur’an: “I feel this! It is speaking directly to me! The Qur’an is reading me!” For the mirror of their heart had remained clean enough to meet the reflection of that light.

Ultimately, decisions are not made by the mind alone. Islam teaches that it is the heart that makes the final choice.

A woman may consider a marriage proposal and see nothing wrong with it objectively: a good family, a good salary, a compatible background… And yet she may say, “My heart says ‘no.’”

We accept this truth: in our most important decisions, it is the heart that guides us.

This is why the Prophet (peace be upon him) speaks of hearts tasting faith. That feeling must be there.

Those who have somehow preserved their inner purity, that is, those who have kept the mirror of their heart clean through consciousness of Allah, feel something awaken within them when they encounter the Qur’an. The light that had been dormant until then recognizes its counterpart (light upon light).

Through this striking example, Allah makes understandable this deep and subtle subject: how a person comes to faith.

From now on, whenever you see a lamp, remember faith. When you notice a bulb that is dusty, dirty and barely giving off light, think: “What have I done to soil my heart?”

A clean glass, left untouched, gathers dust on its own over time; if it is neglected, these layers of dust grow thicker. The parallel is clear: even if we do not consciously do anything wrong, our hearts can rust.

We must continually keep up the effort of spiritual purification: through supplication, by avoiding the things that harden the heart (excessive screen time, useless conversation, overindulgence in desires, excessive attachment to the world), by remembering Allah and by turning to His revelation.

This does not mean rejecting the world entirely; for our Prophet (peace be upon him) ate well, fasted, worshipped, rested, dressed well and took an active part in life. The warning here is directed at excess, which inevitably has spiritual consequences.

If you find it hard to shed tears in worship, that is a sign: serious purification is needed.

These examples make complex truths understandable, memorable and transformative. Whenever we come across a lamp, we remember this profound truth about faith.
