"Allah Is the Light": How Light Illuminates the Quran, Starting from Verse 24:35

Few images in the Quran shine as brightly as light. The Quran speaks of God as light, of light descending into hearts, of lamps and suns and mornings, and of the darkness that light scatters. To read these verses together is to see one continuous story: light is not decoration; it is the very way the Quran describes guidance, life, and the presence of the Divine. This dossier gathers the main passages about light, beginning where so many readers begin — with the radiant [24:35].

The Verse of Light: a lamp in a niche

At the heart of the theme stands [24:35], often called the most quoted verse about light in the entire Quran. It declares that Allah is the Light of the heavens and the earth, then unfolds a vivid parable: a niche (mishkāh, a hollow in a wall made to hold a lamp), a lamp (miṣbāḥ), the lamp inside a glass (zujāja), the glass like a brilliant star, kindled from a blessed olive tree (shajaratun mubāraka) that belongs to neither east nor west. Every word is a step of the eye moving inward: from the tree to the oil, from the oil to the flame, from the flame to the glass, from the glass to the niche. The verse ends by multiplying the image — "light upon light" (nūrun ʿalā nūr) — and by saying that Allah guides to His light whom He wills. The Arabic word nūr, meaning "light," appears here as the verse's pulsing center; the word mubāraka, "blessed," shows that the source of light carries blessing, not just brightness.

The following verse [24:36] extends the parable into the world: such lamps of light are found in houses that Allah has permitted to be raised, where His name is mentioned. Light, in the Quran's imagination, is not only cosmic; it lives in homes where people remember and praise.

Darkness upon darkness: the image of the sea

To feel what light means, the Quran sets it beside its opposite. In [24:40], immediately after the Verse of Light, we read the parable of deeds that have no light: they are like darkness in a deep sea, covered by wave above wave, above which are clouds — "darknesses, one above another." Notice the plural: ẓulumāt, "darknesses," in layers. When the person stretches out a hand, they can barely see it, "and he to whom Allah has not appointed light — for him there is no light." Here nūr returns as something one cannot manufacture for oneself; it must be granted. The contrast could not be more vivid: [24:35] gives layered radiance, [24:40] gives layered dark. The two verses together teach that guidance and misguidance are matters of inner sight.

God as light and the First and the Last

Surah 57, named al-Ḥadīd, "The Iron," opens a window onto light as a divine attribute. In [57:3], Allah is described as "the First and the Last, the Manifest and the Hidden" (aẓ-ẓāhir wa-l-bāṭin) — and He has knowledge of all things. Readers have long connected this verse with [24:35]: light that is manifest everywhere, yet whose source remains hidden and beyond sight. A little later, [57:28] delivers a direct invitation: "O you who believe, fear Allah and believe in His Messenger; He will give you a double portion of His mercy and appoint for you a light (nūran) by which you walk." Light here is explicitly a gift for walking — practical, daily, a lamp for the road of life.

The surah also shows light in the hereafter. In [57:12-13], believers are promised "their light running before them and on their right hand," while the hypocrites beg those who have light to wait so a share may be borrowed — and a wall with a door is raised between the two groups. Light becomes a possession of the heart, visible on the Day when it matters most; and in [57:19], those who believe in Allah and His messengers are called "the truthful and the witnesses with their Lord."

Light descending as revelation

Where does guidance come from? The Quran answers: from above, like light. [14:1] describes the Book revealed "that you may bring humanity out of the darknesses (aẓ-ẓulumāt) into the light (an-nūr), by the permission of their Lord, to the path of the Mighty, the Praiseworthy." The movement is always from plural darkness to singular light — a rhythm repeated across the Quran.

Surah 5 opens with the same confidence: in [5:15-16], the Messenger is told to proclaim that "there has come to you from Allah a light and a clear Book" (nūrun wa-kitābun mubīn), through which Allah guides those who seek His good pleasure to paths of peace and brings them out of darknesses into light. And in [42:52], the Prophet himself is addressed: "We revealed to you a spirit of Our command (rūḥan min amrinā)" — a word often linked by commentators to the light of revelation — "you did not know what the Book was, nor the faith; but We made it a light by which We guide whom We will of Our servants." Revelation, in these verses, is the fitting form of divine light: it illuminates the mind the way a lamp illuminates a room.

The Quran also insists that this light cannot be extinguished. In [9:32] and [61:8], we read of those who "wish to extinguish the light of Allah with their mouths," but Allah refuses except to perfect His light, "though the disbelievers dislike it." The image is almost humorous in its disproportion: blowing at the sun.

The Prophet as light and as lamp

Some passages describe the Messenger with words of illumination. In [33:45-46], the Prophet is called "a lamp that gives light" (sirājan munīran) — literally a burning lamp — sent as a witness and a bearer of good news. In [7:157], those who follow the Messenger, "the unlettered prophet whom they find written with them in the Torah and the Gospel," are promised that "he will relieve them of their burdens" and that they believe in him, honor him, and support him — a passage deeply tied to the light of following guidance. And in [64:8], the call is universal: "Believe in Allah and His Messenger and the light that We have sent down" (wa-n-nūri alladhī anzalnā). Many readers understand this light as the Quran itself; the verse leaves the image generous and open.

Proof and clear seeing: burhān and baṣīra

Light in the Quran is not only a feeling; it is clarity of judgment. [4:174] says: "O humanity, there has come to you a conclusive proof (burhānun) from your Lord, and We have sent down to you a clear light" — again nūran mubīn. Burhān means decisive evidence, the kind that settles a question. In [6:122], the contrast between the living and the dead is drawn through sight: one who was dead and whom Allah gave life, "and appointed for him a light by which he walks among people," is like one in darknesses from which he cannot emerge. The phrase kharaṭa fī aẓ-ẓulumāt, "he wanders bewildered in the darknesses," gives the exact flavor of a life without inner light.

In [2:17], the Quran offers a memorable parable of those who abandon what they received: they are like one who kindled a fire; "when it illuminated what was around him, Allah took away their light and left them in darknesses, so they do not see." A borrowed, self-made flame goes out. By contrast, [2:257] gives one of the most cherished sentences of the whole Book: "Allah is the ally (walī) of those who believe; He brings them out of the darknesses into the light." True light, unlike the fire of [2:17], is permanent because its giver is.

Light written into creation

The natural world carries the same vocabulary. In [10:5], Allah is "He who made the sun a shining brightness (ḍiyāʾan) and the moon a light (nūran)" and determined stations for it, "that you may know the number of years and the reckoning." In [25:61], praise rises to the One who "placed in the heaven constellations and made therein a lamp (sirājan) and a shining moon (qamaran munīran)." And [71:16] repeats the pairing: the moon as a light, the sun as a lamp. Two words matter here. Ḍiyāʾ suggests radiance that streams out from a source, like the sun; nūr in these creation verses is used for the moon, which receives and reflects its light. Many readers have seen in this gentle distinction an echo of the Verse of Light: all brightness, whether made directly or reflected, belongs to the One who is Light itself.

The earth, too, receives its share. In [39:69], on the Day of Resurrection, "the earth will shine with the light of its Lord" (nūri rabbihā) and the Book will be set, and the prophets and witnesses will be brought. Light, hidden through history, becomes visible at the end of history.

Hearts softening into light

The Quran traces an inner geography of light. In [39:22], the one whose "breast Allah has opened to Islam" walks "upon a light from his Lord" (ʿalā nūrin min rabbihi) — while woe is announced to hearts hardened against remembrance. The famous verse [13:28] names the remedy for the restless heart: "Those who believe and whose hearts find rest in the remembrance of Allah (bidhikri llāhi taṭmaʾinnu l-qulūb)." Remembrance (dhikr) is described across the tradition as the oil that keeps the lamp burning; the verse itself does not use the word nūr, but its place in this family of passages is secure — a heart at rest is a heart receiving light.

In [6:1], praise belongs to Allah "who created the heavens and the earth and made the darknesses and the light" — the pair appears at the very threshold of creation, as if light and dark were the first letters of the alphabet of existence. And in [76:11], in the description of the righteous, "Allah will protect them from the evil of that Day and cause them to meet radiance and gladness" (naḍratan wa-surūran). Light and joy arrive together, like two friends at a door.

The believers' prayer for light

The Quran does not only describe light; it teaches words to ask for it. In [66:8], believers are urged to repent sincerely, "perhaps your Lord will cover your misdeeds and admit you to gardens beneath which rivers flow, on the Day when Allah will not disgrace the Prophet and those who believed with him — their light running before them and on their right hands," as they pray: "Our Lord, perfect for us our light and forgive us" (rabbanā atimma lanā nūranā). The prayer is short enough for anyone to memorize and hold for a lifetime: complete our light.

That prayer answers the one warning image we have already met, in [57:13], where light cannot be borrowed at the last hour. Together the verses form a quiet lesson: light is gathered in small daily acts of faith, remembrance, and repentance, so that it will be there when it is needed.

The growth of light: a parable of a seed

Not all light-images in the Quran are about lamps. In [24:39-40], deeds without faith are dust swept by wind; in [13:17], pure substance endures like scum-free metal after smelting. But the most tender parable of growing light stands in [14:24-25]: "A good word is like a good tree — its roots firm and its branches in the sky, giving its fruit every season by permission of its Lord." The tree recalls the blessed olive tree of [24:35]; a word spoken in faith, like oil from the blessed tree, becomes fuel for light that keeps giving. And [41:53] closes the circle with a promise: "We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the truth." Signs outside, signs inside — the same light, seen from two directions.

Living with the Verse of Light

Read from beginning to end, these passages sketch a single path. Light belongs first to Allah, the Light of the heavens and the earth [24:35]. It descends as revelation [14:1], [5:15], [42:52], and becomes a lamp in the person of His Messenger [33:45]. It enters creation as sun, moon, and morning [10:5], [25:61]. It is offered to every heart as remembrance, sincerity, and a good word [13:28], [66:8], [14:24], until it finally runs before the believer on the Day when "the earth shines with the light of its Lord" [39:69], [57:12-13]. Whoever reads [24:35] slowly — niche, glass, lamp, olive, light upon light — holds in one verse the whole grammar of this theme: light is given, not taken; it begins above and ends in a heart; and its only condition is that we keep turning toward it.
