The Sun Setting in a Muddy Spring: Why Qur’an 18:86 Remains Controversial

وَجَدَهَا تَغْرُبُ فِي عَيْنٍ حَمِئَةٍ

“he found it setting in a muddy/murky spring.”

That wording is the problem. The Arabic does not explicitly say, “it appeared to him as if.” Some modern translations add wording like “appeared to him” to make the verse read as visual perspective rather than literal description. But that is not a neutral translation choice; it is an interpretive rescue. It may be theologically motivated and defensible from within Islamic belief, but critics are right to point out that it goes beyond the bare wording of the verse.

The common Muslim defense is that the Qur’an is using phenomenological language, the same way people today say “sunrise” and “sunset” without meaning the sun literally moves around the earth. That argument has some surface plausibility. Scripture and ordinary speech often use appearance-based language. But Qur’an 18:86 is not merely saying “the sun set.” It places Dhul-Qarnayn at the sun’s “setting-place” and says he found it setting in a spring. That makes the passage more difficult than normal sunset language.

Classical tafsir also shows that this was not simply a modern anti-Islamic invention. Early and medieval Muslim commentators preserved the difficult wording and discussed whether the spring was muddy, dark, blackened, or hot. Tafsir al-Jalalayn explains the spring as muddy while also noting the description can be understood according to what the eye sees. Tanwir al-Miqbas, in the Ibn ‘Abbas tradition, describes a blackened, muddy spring and also mentions a hot-spring reading. Ibn Kathir likewise preserves the discussion of the two readings: ḥamiʾah meaning muddy/murky and ḥāmiyah meaning hot. The point is not that every Muslim commentator read the verse crudely literally. The point is that the wording was difficult enough to require explanation.

The related hadith makes the issue worse. In Sahih al-Bukhari 3199, Muhammad asks Abu Dharr where the sun goes at sunset. Abu Dharr replies that Allah and His Messenger know best. Muhammad then says the sun goes until it prostrates beneath the Throne, asks permission, and rises again. The hadith connects this to Qur’an 36:38. This is not a random fringe report; Sahih al-Bukhari is one of Sunni Islam’s most authoritative hadith collections.

Muslim apologists often respond that the hadith describes unseen reality, not astronomy, or that the sun’s prostration is metaphorical. But that answer again depends on interpretation. The text itself describes the sun as going somewhere, prostrating beneath the Throne, asking permission, and returning. When read alongside Qur’an 18:86, it strengthens the critic’s case that these passages reflect a premodern cosmological framework rather than merely poetic language.

A fair but critical conclusion is this: the “muddy spring” objection is not based on a fake translation or a cheap misunderstanding. The Arabic really does say Dhul-Qarnayn found the sun setting in a muddy/murky spring. Muslim responses exist, but they usually depend on inserting a perspective-based explanation that the Arabic itself does not explicitly provide. That is why the passage remains controversial: the natural reading is awkward, the classical tradition shows the tension, and the related Bukhari hadith makes the issue harder to dismiss.
