Sun Setting In Murky Water

Qur’anic Commentary on Sura’ Al-Kahf (18):86: Of The Sun Setting In A Spring Of Murky Water

Reading Time: 6 minutes

Dhul-Qarnayn (Arabic: ذو القرنين‎ ḏū’l-qarnayn), “he of the two horns” (or “he of the two ages”), appears in the Quran as a figure empowered by God to erect a wall between mankind and Gog and Magog, the representation of chaos. Dhul-Qarnayn is generally described as a righteous ruler who travelled to spread the message of God. Of interest is this verse from Qur’an, 18:86 which has recently raised much ruckus among the enemies of Islam.

The following English translation was taken from A. Yusuf Ali:

“Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it, he found a People: We said: “O Dhul-Qarnayn! (thou hast authority) either to punish them, or to treat them with kindness.” (Qur’an, 18:86)

A common Christian missionary “objection” to the verse above is by claiming it to be a “scientific contradiction”.

    If the presence of scientific facts can prove the Qur’an’s divine origins, the presence of scientific falsehood can disprove divine origins. For example, Sura’ 18:86:

    “Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: “O Dhul-Qarnayn! (thou hast authority,) either to punish them or to treat them with kindness.”

    Since we all know that the sun does not set in a spring of murky water and, therefore, this is a big error. However, Muslim apologists are quick to tell us that this is only poetic and not a “scientific miracle”! This type of apologetic is intellectually dishonest as well as a bit silly.

So who is the one that is actually “intellectually dishonest as well as a bit silly”? Let us analyse the verse part by part.

Analysis Of The Verse

“Until, when he reached the setting of the sun…”: The translation of this part of the verse does not say that Dhul-Qarnayn reached the place where the sun sets literally, rather it means here that Dhul-Qarnayn was facing the direction in which the sun is setting. The “setting of the sun,” is an Arabic idiom meaning ‘the western-most point’ of his expedition. However, in general, idioms should not be literally translated.

“…he found it set in a spring of murky water”: The Qur’an is obviously describing what Dhul-Qarnayn saw. What Dhul-Qarnayn saw was the image of the sun setting in a dark body of water. Since the Qur’an is clearly describing this from Dhul-Qarnain’s direct point of view (the Qur’an is quite explicit here in doing that), there is, in fact, no problem with the description of what Dhul-Qarnain saw. Of course, one is correct in saying that “the sun does not set in a spring of murky water”, but try standing at a beach during the time when the sun is about to set and anyone would be able to see the sun “entering” the sea far in the horizon. This, therefore, gives us the conclusion that Dhul-Qarnayn was somewhere west and by a large body of water, possibly the sea.

The Qur’an, unlike descriptive prose, possesses a high level of poetical eloquence, a quality not found in the Bible. This poetic nature is integral to its beauty, and thus, it naturally employs emphatic expressions, such as a “sunset.” Critics should understand this context before evaluating the text.

Additionally, the Qur’an, with its poetical prose, was intended as a challenge to the pagan Arabs in Mecca who valued high-quality poetry. Those newcomers who wield this verse as a weapon against Islam would be well-advised to study Arabic literature and the historical context of that era before making uninformed conclusions.

Moreover, it is important to note that the verse actually indicates that Dhul-Qarnain traveled westward, observing the sun setting over the horizon. It appeared to him as if the sun was sinking into a murky-looking sea, an observation any beach-goer observing a sunset might make. Critics may not have taken such experiences into account.

Lastly, for further comprehension of our explanation, we present two alternative translations of the same verse, provided by M. M. Pickthall and Shakir.

    Translation by M. M. Pickthall

    Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout. We said: O Dhu’l-Qarneyn! Either punish or show them kindness. (Qur’an 18:86)

    Translation by Shakir

    Until when he reached the place where the sun set, he found it going down into a black sea, and found by it a people. We said: ‘O Zulqarnain! either give them a chastisement or do them a benefit.’ (Qur’an 18:86)

We can see that the general agreement of the translations of this verse is that Dhul-Qarnain saw the sun setting into the horizon that it looks like it is set into a body of water (sea) that looks murky-looking. That this verse was never taken literally was not alien in the understanding of the early commentators.

How The Early Commentators Understood The Verse


In his famous commentary known as al-Jami’ li-Ahkam al-Quran, al-Qurtubi (died 671 AH/1273 CE) wrote about this verse:

    It is not meant by reaching the rising or setting of the sun that he reached its body and touched it because it runs in the sky around the earth without touching it and it is too great to enter any spring on earth. It is so much larger than earth. But it is meant that he reached the end of populated land east and west, so he found it – according to his vision – setting in a spring of murky water as we watch it in smooth land as if it enters inside the land. That is why He said, “he found it rising on a people for whom we had provided no covering protection against the sun.” (Holy Qur’an 18:90) and did not mean that it touches or adheres to them, but they are the first to rise on. Probably this spring is a part of the sea and the sun sets behind, with or at it, so the proposition takes the place of an adjective and God knows best.1

Fakhr al-Din al-Razi

Fakhr al-Din al-Razi (d. 1209 CE) wrote in his commentary on the same verse that:

    When Zul-Qarnain reached the furthest west and no populated land was left, he found the sun as if it sets in a dark spring, but it is not in reality. The same when sea traveller sees the sun as if it sets in the sea if he cannot see the shore while in reality, it sets behind the sea.2

Ibn Kathir

Ibn Kathir (701-774 AH/1302-1373 CE) wrote in his commentary about this verse that:

    “Until, when he reached the setting of the sun” means he followed a certain way until he reached the furthest land he could go from the west. As for reaching the setting of the sun in the sky, it is impossible. What narrators and storytellers say that he walked for a period of time in earth while the sun was setting behind him is unreal, and most of it is from myths of People of the Book and inventions of their liars. “he found it set in a spring of murky water” means he saw the sun according to his vision set in the ocean and this is the same with everyone ending to the shore seeing as if the sun sets inside it (i.e. the ocean).3


According to Al-Mawardi (d. 450 AH) in his tafsir, the verse can be understood as:

    That He (Dhul Qarnayn) wajadaha (found it, saw it) setting behind the spring (‘ayn) as if it was setting in the very spring.”4

Metaphorical Interpretations of a Sunset

To further reinforce our assertion that the cited Quranic verse is indeed poetic in nature and not meant to be interpreted literally or scientifically, let’s consider the beautiful imagery of the sun setting at the horizon.


In a picture, the sun appears to descend and “dissolve” into the horizon. This imagery is often used in literature and poetry as a metaphor or symbol. Similarly, in the context of the Quran, the verse could be employing metaphorical language to evoke certain feelings or concepts.

When observing a sunset, one might perceive the sun to be swallowed by the earth, disappearing beneath the horizon line, which could be easily interpreted as the sun ‘setting into the earth’. This is, however, just an optical illusion created by the Earth’s rotation and the observer’s vantage point. Scientifically, we know that the sun does not literally sink into the earth or sea at sunset. Rather, the sun continuously moves in its own orbit, as the Earth spins on its axis.

In the image, the sun, setting into the horizon, could be seen as a metaphor for the conclusion of a day, the ending of a phase, or the transient nature of life, among other things. The image’s beauty and emotional impact provide a more profound understanding than a literal interpretation.

Considering this, it’s plausible that the verse in the Qur’an, which could be perceived as suggesting a non-scientific viewpoint, is in fact using poetic and metaphorical language. This interpretation falls in line with the tradition of Quranic exegesis, where scholars recognize the frequent use of metaphors, symbols, and allegories.

So, when it comes to understanding ancient religious texts like the Qur’an, it is often beneficial to consider their poetic, cultural, and historical contexts rather than strictly literal or modern scientific interpretations.


The allegation put forth against the Qur’an is utterly baseless and is refuted by the Arabic language itself. The verse contains no reference at all to the sun literally setting, or entering, or going down, into a muddy pool of water. It is clear to us that the above-mentioned verse is only considered “unscientific” if we would also consider that similar emphatically-used phrases such as “Japan, the land of the rising sun” or “Sabah, the land below the wind” to be “unscientific” as well.

Our advice to those neophytes is that before they try to find any more “discrepancies” in the Qur’an they should consider the following discrepancy of the Bible to clarify which Book actually has a severe defect:

    And the hare, because he cheweth the cud, but divideth not the hoof; he is unclean unto you. (Leviticus 11:6)

Now we all know that the hare (or anything related to rabbits) do not chew cud. Is this a “poetical” expression of the Bible? And only God knows best!Endmark

    Theres twitter thread about this that appeared with hadith supported evidence saying our prophet(pbuh) said that the sun set in the spring of warm water and also with another one with the SAME PERSON NARRATION WITH SAME QUESTION tells different answer which is to ask permision to prostrate (but his version is a bit weird like keep on using the word prostration), the hadith one with asking permission to prostate got repeated 6 times while the one that said “it in the spring or warm water” just once only. That hadith with “it in the spring water” is so suspicious. But quran says a lot about the universe and it celestial being floating in an orbit to be suddenly one verse that says the sun jump out of it orbit just to crash with the earth into the spring of water with the word HE FOUND in the started of the verse, just shows allah s.w.t know what is dzhul qurnain saw with his eyes and all of these the spring, the sun, the people just seems like “setting” a story for me with time, place and people setting of story. And probably that dzhul-qurnahin, arrived there at VERY LATE EVENING WHERE THE SUN IS LIKE HALF IN THE SEA/etc where there has spring where theres community lived. I’ve been thinking about this verse for three days now, its seriously frustrated me. Theres also a verse said that allah s.w.t doesnt want to teach poetry to muhammad(s.a.w) though but its probably just when allah s.w.t told our prophet what to say to those people.

    May peace be with you, and peace be with me too cause i need it.

    The link to above post reviews verses of Quran related to Zal-qarnain. The terms ‘murky water, ‘no protection against the sun’ and ‘wall between mountains’ give geographical clues to the places where Zal-qarnain could have visited.

    Does anyone know of any commentary that explains why the “rising of the sun” and “setting of the sun” is a recurrent theme inside Surah Kahf?
    It is discussed with the sleepers of the cave and also with Dhul Qarnain. I can’t think of anywhere else in the quran where this particular phrase is repeated like this.
