Key takeaway
The Quran consistently calls the sun a sirāj ("burning lamp") and ḍiyāʾ ("shining light"), and the moon nūr ("light," rendered "[reflected] light" or "derived light" by Saheeh International) and munīr ("luminous"). It never reverses the terms. This matches the physical fact that the sun produces its own light by nuclear fusion while the moon only reflects sunlight.
The verses
تَبَارَكَ ٱلَّذِى جَعَلَ فِى ٱلسَّمَآءِ بُرُوجًا وَجَعَلَ فِيهَا سِرَٰجًا وَقَمَرًا مُّنِيرًا ٦١
Blessed is He who has placed in the sky great stars and placed therein a [burning] lamp and luminous moon.
وَجَعَلَ ٱلْقَمَرَ فِيهِنَّ نُورًا وَجَعَلَ ٱلشَّمْسَ سِرَاجًا ١٦
And made the moon therein a [reflected] light and made the sun a burning lamp?
هُوَ ٱلَّذِى جَعَلَ ٱلشَّمْسَ ضِيَآءً وَٱلْقَمَرَ نُورًا وَقَدَّرَهُۥ مَنَازِلَ لِتَعْلَمُوا۟ عَدَدَ ٱلسِّنِينَ وَٱلْحِسَابَ ۚ مَا خَلَقَ ٱللَّهُ ذَٰلِكَ إِلَّا بِٱلْحَقِّ ۚ يُفَصِّلُ ٱلْـَٔايَـٰتِ لِقَوْمٍ يَعْلَمُونَ ٥
It is He who made the sun a shining light and the moon a derived light and determined for it phases - that you may know the number of years and account [of time]. Allāh has not created this except in truth. He details the signs for a people who know.
وَجَعَلْنَا سِرَاجًا وَهَّاجًا ١٣
And made [therein] a burning lamp
Key Arabic terms
| Arabic | Transliteration | Meaning |
|---|---|---|
| سِرَاجًا | sirāj | a lamp that burns and gives off its own light and heat |
| وَهَّاجًا | wahhāj | blazing, intensely hot and bright |
| ضِيَآءً | ḍiyāʾ | radiant light; classical lexicographers often treat it as light that comes from a body itself |
| نُورًا | nūr | light or illumination in general; for the moon, a gentle, borrowed light |
A consistent vocabulary
Wherever the Quran describes the two great luminaries together, the sun receives words of burning and self-generated radiance: sirāj in Quran 25:61 and Quran 71:16, sirāj wahhāj ("a burning lamp") in Quran 78:13, and ḍiyāʾ in Quran 10:5. The moon receives nūr and munīr. Saheeh International reflects this by translating nūr for the moon as "[reflected] light" or "derived light." The bracket marks the translator's interpretive gloss.
The science
The Sun is a star that converts hydrogen into helium by nuclear fusion in its core and radiates energy as light and heat. The Moon has no light of its own. Moonlight is sunlight reflected off the lunar surface, and only about 12% of the light falling on the Moon is reflected.
Historical honesty
That the moon reflects sunlight was not unknown before Islam. The Greek philosopher Anaxagoras (5th century BCE) taught it, and it appears in later Greek astronomy. So the point here is not a claim of unprecedented discovery. It is the observation that the Quran's word choice is precise and never confused, unlike many ancient texts that simply call both bodies "lights."
Balanced assessment
Moderate A reasonable, accurate correspondence; the words have other valid meanings or the fact was partly known before.
The consistent distinction is real and accurate. Calling it a "miracle" would overstate the case, since the fact was known to some ancient astronomers. It is better seen as an example of the Quran's precise vocabulary, which never contradicts what we now know.
Frequently asked questions
Does the Quran say the moon reflects light?
The Quran calls the sun a burning lamp (sirāj) and the moon a light (nūr). It consistently distinguishes the sun as a source of light from the moon, which Saheeh International renders as "[reflected] light."
