One of the most repeated objections claims the Quran teaches that the sun literally sets in a pool of muddy water - a primitive cosmology that would expose the book as unscientific. The verse is doing nothing of the kind. The classical tafsir tradition understood it as describing what Dhul-Qarnayn saw from where he stood, in ordinary observational language.

The verse and the objection

Until, when he reached the setting-place of the sun, he found it setting in a spring of murky water, and he found near it a people...

Quran 18:86

Critics read this as a factual cosmological claim: that the sun physically descends into a muddy spring at the edge of a flat earth. From there they conclude that the Quran endorses a false, primitive picture of the world.

It describes appearance, not the sun's physical location

The phrase is wajadaha taghrubu (وَجَدَهَا تَغْرُبُ) - "he found it setting." The argument should not be built on claiming that wajada by itself simply means "saw." Rather, the point is how the phrase was understood in context by the mufassirun: it reports the sunset as it appeared to Dhul-Qarnayn from his vantage point.

This is completely ordinary language, then and now. A person standing on a shoreline can truthfully say, "I watched the sun sink into the ocean," and no one imagines the sun has entered the water. The Quran is narrating the scene as it appeared to the traveller who had journeyed west until the sun appeared, from where he stood, to set into a dark body of water. Describing an appearance is not asserting a physical mechanism.

The two established readings of the spring

There are two accepted Quranic recitations of the phrase, both linguistically valid:

  • aynin hamiah (عَيْنٍ حَمِئَةٍ) - a muddy or dark spring.
  • aynin hamiyah (عَيْنٍ حَامِيَةٍ) - a hot spring.

Al-Tabari acknowledged both readings as recognized recitations. The difference does not create the objection: whether the water was described as muddy/dark or hot, the point remains that the sunset appeared to meet that body of water from the traveller's perspective.

The classical commentators already said this

This is not a modern rescue. Ibn Kathir explains the verse by saying that Dhul-Qarnayn saw the sun as if it were setting in the ocean, as anyone who reaches a coastline may see it from his viewpoint.

Al-Qurtubi and al-Baghawi likewise record the explanation that it was "in the sight of the eye" - that is, according to what appeared to the observer, not according to the sun's actual physical resting place. This is the natural meaning: a visual description from the standpoint of a traveller at the western limit of his journey.

The context strongly confirms it

The same verse immediately continues:

...and he found near it a people.

Quran 18:86

Dhul-Qarnayn reaches a geographical location - one that contains water and a human community. The wider passage has the same travel frame: he journeys west and meets a people, then journeys east and finds the sun rising upon another people:

Until, when he reached the rising-place of the sun, he found it rising upon a people for whom We had not made against it any shelter.

Quran 18:90

No one imagines that verse means the sun physically emerges from a hole next to that eastern community. It is plainly observational language relative to inhabited places on earth. The same reading applies to the western scene in 18:86.

What about the hadith in Sunan Abi Dawud?

Some critics also cite the report of Abu Dharr in which the Prophet (PBUH), referring to the sun, is reported to have said:

It sets in a hot spring.

Sunan Abi Dawud 4002

This wording should be addressed carefully. It should not be dismissed casually as fabricated or worthless: al-Albani graded its isnad sahih. At the same time, hadith criticism does not only ask whether one chain is acceptable in isolation; it also compares wordings and routes to determine which wording is most preserved.

The much stronger and more famous versions of the Abu Dharr incident in Sahih al-Bukhari and Sahih Muslim do not contain the "hot spring" wording. They report the Prophet (PBUH) speaking of the sun going and prostrating beneath the Throne, then seeking permission to rise. For this reason, some scholars hold that the established wording of the Abu Dharr report is the prostration version, not the additional "hot spring" wording found in Abi Dawud.

Even if the Abi Dawud wording is accepted, it is read in the same observational way as the Quranic verse. It describes where the sun appears to set at the horizon from the viewpoint of the observer. This is exactly how Ibn Kathir explains Quran 18:86: the observer at the edge of a sea or western shore sees the sun as if it is setting into the water, while the sun is not literally entering an earthly spring.

The objection reads against the grain of the text

To manufacture the error, the critic must treat a description of appearance as a claim of physical fact, ignore the explanations of the classical mufassirun, and overlook the travel context in which Dhul-Qarnayn encounters inhabited peoples in the west and east. These moves are made against the verse, not with it.

Many modern translations make the observational sense explicit - "as if" or "as it appeared to him" - not to patch a problem, but to convey what the tafsir tradition already recognized.

Conclusion

The Quran does not teach that the sun literally sets in muddy water. It reports what Dhul-Qarnayn encountered on his western journey: from his position, the sun appeared to set into a dark or hot body of water near an inhabited people. This is ordinary human language about sunsets, and it is exactly the way major classical commentators such as Ibn Kathir, al-Qurtubi, and al-Baghawi explained the verse. The objection mistakes a description of perspective for a statement of cosmology.
