2. Quran Says the Sun Sets in a Muddy Spring
1. Quran
"Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout." Quran 18:86
Quran 18:86 in Arabic word for word creates two independent problems:
- First, Dhul Qarnayn reached (balagha) a location: the setting place of the sun (maghriba l-shamsi).
- There, he found (wajada) the sun setting in a muddy spring (ʿaynin ḥami-atin). And he found (wajada) a community near it.
Quran 18:86 Word for Word Arabic

Tafsir al-Tabari: Companion Ibn Abbas and the Salaf Debate on Whether the Spring in Which the Sun Sets Is Muddy or Hot
Tafsir al-Tabari preserves the debate between Muhammad's Companion Ibn Abbas and the salaf over whether the spring where the sun sets is muddy or hot. Tabari says both readings are correct because the sun could set in a spring that is both hot and muddy.
Tafsir al-Tabari on Quran 18:86
Allah says: (Until, when Dhul-Qarnayn reached the setting of the sun, he found it setting in a muddy spring.) The readers differed on how to read this. Some of the readers of Medina and Basra read it as (in a muddy spring), meaning that the sun sets in a spring that contains mud. While a group of the readers of Medina and the majority of the people of Kufa read it as, (in a warm spring) meaning that the sun sets in a spring of warm water. The people of commentary have differed on the meaning of this depending on the way they read the verse.
Mention of those who said: setting in a muddy spring
Muhammad b. Al-Muthanna ← Ibn Abi Uday ← Dawud ← Ikrimah ← Ibn Abbas: (and he found it setting in a muddy spring) he said: In black mud.
Ibn al-Muthanna ← Abd al-Ala ← Dawud ← Ikrimah on the authority of Ibn Abbas, that he recited: (in a muddy spring) he said: it is black mud.
Al-Husayn b. Al-Junayd ← Sayd b. Salamah ← Ismail b. Aliyah ← Uthman b. Hadir: I heard Abdullah b. Abbas said: Muawiyah recited this verse, and he said (warm spring) and Ibn Abbas said: it is (muddy spring). He said: So they sent to Ka'b Al-Ahbar and asked him. Ka'b said: As for the sun, it disappears in 'Thatin', which matched what Ibn Abbas said, and the word tha'at means "mud".
Yunus ← Ibn Wahb ← Nafi' b. Abu Na'im ← Abd Al-Rahim Al'Araj: Ibn Abbas used to speak about the muddy spring and would pronounce the word as (in a muddy spring) then he explained it as black mud. Nafi' said that Ka'b was asked about it and he said: "You are more knowledgeable in the Quran than I am, but I find it in the Book disappearing in black mud."
Muhammad b. Saad ← his father ← His uncle ← his father ← his father ← Ibn Abbas: (and he found it setting in a muddy spring) he said: it is black mud.
Muhammad b. Amr ← Abu Asim ← Issa ← Ibn Abi Najih ← Mujahid: (in a muddy spring). He said: black mud.
Al-Qasim ← Al-Husayn ← Hajjaj ← Ibn Jurayj ← Mujahid: (it setting in a muddy spring). he said: mud.
He said: And Amr b. Dinar ← Ata b. Abi Rabah ← Ibn Abbas: I read (in a muddy spring) And Amr bin Al-Aas recited (in a warm spring), so we were sent to Ka'b. He said: It sets into black mud.
Bishr ← Yazid ← Sayd ← Qatadah: (setting in a muddy spring) and the mud: the black mud.
Muhammad b. 'Abd al-A'laa ← Marwan b. Mu'awiya ← Warqa ← Sayd b. Jubayr: Ibn 'Abbas used to read this letter (In a muddy spring) and he said: Black mud that the sun sets in.
Others said: Rather, it disappears in a hot spring. Mention of those who said that:
Ali ← Abdullah ← Muawiyah ← Ali ← Ibn Abbas (he found it setting in a warm spring) and he said: In a hot spring.
Yaqub ← Ibn Aliyah ← Abu Raja ← al-Hasan: (In a warm spring) he said: it is hot.
Al-Hasan ← Abd al-Razzaq ← Mamar: al-Hasan regarding (In a hot spring) he said: It is hot. al-Hasan also read it this way.
And in my (Tabari's) mind the correct opinion is to say that they are both popular readings in the land, and each one has a correctness about it and an understandable meaning, and neither contradicts the other, for it is possible that the sun sets in a hot spring that has mud and sludge, so a reader who uses "hot spring" is describing its temperature, and the reader who uses "muddy spring" is describing that it has mud and sludge. Both versions have been narrated to us.
Muhammad b. Al-Muthanna ← Yazid b. Harun ← The common people ← A freed slave of Abdullah b. Amr ← Abdullah: "The Messenger of Allah, may Allah bless him and grant him peace, looked at the sun when it set, and said: 'In the blazing fire of Allah, in the blazing fire of Allah: If it wasn't for Allah's command, the sun would burn all those who are on earth.'"

Full Dhul Qarnayn Story (Quran 18:83-99)
The Dhul Qarnayn story begins: “They will ask thee of Dhu'l-Qarneyn.” In it, he traveled until he reached (balagha) the setting place of the sun and found (wajada) the sun setting in a muddy spring, and found (wajada) a community near it. Then he reached (balagha) the rising place of the sun where people had no shelter from it. Then he followed another path until he reached (balagha) a place between two mountains, where he found (wajada) a people asking for help against Gog and Magog. He built an iron and copper wall between the cliffs to seal them off until doomsday. Quran 18:83-99.
2. Hadith
Muhammad directly says in a hadith, considered authentic in chain, that the sun sets in a spring:
"I was sitting behind the Messenger of Allah who was riding a donkey while the sun was setting. He asked: Do you know where this sets? I replied: Allah and his Apostle know best. He said: It sets in a spring of warm water (Hamiyah)." Sunan Abu Dawud 4002
3. Pre-Islamic Poem
A poem in Ibn Ishaq's biography of Muhammad, attributed to the pre-Islamic king Tubba, describes this as well:
"He saw where the sun sinks from view"
"In a pool of mud and fetid slime" Ibn Ishaq, Sirat Rasul Allah, p. 12
4. Syriac Alexander Legend
The Dhul Qarnayn story begins: “They will ask thee of Dhu'l-Qarneyn” Quran 18:83, showing the story was circulating at the time. Historians trace the Quranic character Dhul Qarnayn to a legend about Alexander the Great circulating around Muhammad's time, the Syriac Alexander Legend, which also says this:
"So the whole camp mounted, and Alexander and his troops went up between the fetid sea and the bright sea to the place where the sun enters the window of heaven; for the sun is the servant of the Lord, and neither by night nor by day does he cease from his travelling. The place of his rising is over the sea, and the people who dwell there, when he is about to rise, flee away and hide themselves in the sea, that they be not burnt by his rays; and he passes through the midst of the heavens to the place where he enters the window of heaven... And when the sun enters the window of heaven, he straightway bows down and makes obeisance before God his Creator; and he travels and descends the whole night through the heavens, until at length he finds himself where he rises." Budge, Syriac Alexander Legend, p. 148
Questions Raised by Quran 18:83-99 That Only the Syriac Alexander Legend Answers
1. Why Is Dhul Qarnayn Called "The Two-Horned One"?
Quran's Question:
Why is he called "Dhu'l-Qarneyn", meaning "The Two-Horned One"?
"They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance of him."Quran 18:83
Alexander Legend's Answer:
God gave Alexander horns on his head as weapons to destroy kingdoms.
"thou hast made me horns upon my head, wherewith I might thrust down the kingdoms of the world"Budge, Syriac Alexander Legend, p. 146
2. Why Do the People at the Sun's Rising Place Have No Shelter?
Quran's Question:
Why did the people that Dhul Qarnayn found at the rising place of the sun have no shelter from it?
"Till, when he reached the rising-place of the sun, he found it rising on a people for whom We had appointed no shelter therefrom."Quran 18:90
Alexander Legend's Answer:
The sun's heat at its rising place is so intense that it splits rocks, forcing them to run and hide in caves.
"the people who dwell there, when he is about to rise, flee away and hide themselves in the sea, that they be not burnt by his rays ... as soon as they see the sun passing [over them], men and birds flee away from before him and hide in the caves, for rocks are rent [split] by his blazing heat and fall down"Budge, Syriac Alexander Legend, p. 148
3. Why Does Dhul Qarnayn Randomly Punish Wrongdoers at the Setting Place of the Sun?
Quran's Question:
After Dhul Qarnayn reaches the setting place of the sun, finds it setting in a muddy spring and also finds a people near it, why does Allah (for no apparent reason) give him the option to either punish the people or show them kindness? And why does Dhul Qarnayn choose to punish the wrongdoers among them?
"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. He said: As for him who doeth wrong, we shall punish him"Quran 18:86-87
Alexander Legend's Answer:
Alexander used condemned criminals to confirm that the fetid sea at the edge of the world was deadly and unsafe to cross.
"Now Alexander thought within himself, 'If it be true as they say, that everyone who comes near the foetid sea dies, it is better that these who are guilty of death should die'"Budge, Syriac Alexander Legend, p. 148
Yale scholar Kevin van Bladel:
"When Alexander came to the people in the west, he tested the efficacy of the deadly, fetid waters with the lives of convicts. This passage helps to explain the option given, for no apparent reason, by God to Dhu l-Qarnayn in the Qur'an: either to punish the people or to do them a kindness. Dhu l-Qarnayn says he will punish only wrongdoers (man zalama), who are like the prisoners sentenced to death in the Syriac text, described there as evil-doers (abday-bishe)."van Bladel, p. 181

Academic Research
"Thus, quite strikingly, almost every element of this short Qur'anic tale finds a more explicit and detailed counterpart in the Syriac Alexander Legend." van Bladel, p. 181

"Could the Syriac text have its source in the Qur'an? If this were the case, then the Syriac text would have to be seen as a highly expanded version of the Qur'anic account... However, the Syriac text contains no references to the Arabic language the type of which one might expect to find if its purpose was to explain an Arabic text, and it is impossible to see why a Syriac apocalypse written around 630 would be drawing on an Arabic tradition some years before the Arab conquests, when the community at Mecca was far from well known outside Arabia. Moreover, the very specific political message of the Alexander Legend would not make any sense in this scenario. This possibility must therefore be discounted." van Bladel, p. 189

More Studies
"The Qurʾān’s accounts of the Companions of the Cave and the travels of Dhū ’l-Qarnayn strongly resonate with popular late antique Syriac Christian stories, namely, accounts of the so-called Sleepers of Ephesus and of Alexander the Great ... it is likely that oral versions of these narratives preceded their surviving written accounts and that the Qurʾān recalled aspects of these oral versions for its own purposes." Griffith, "The Narratives of Sūrat al-Kahf"
"The evidence presented here suggests that the Neṣḥānā [Syriac Alexander Legend] served as a key source of inspiration for the Qurʾānic portrayal of Dhū-l-Qarnayn, supporting his identification as an Alexander figure reinterpreted through the lens of Syriac literary and ideological traditions." Tesei, "And they ask you about Dhū-l-Qarnayn."
Both Syriac Alexander Legend and Hadiths: Sun Dips Then Bows Before God
Same motif across the Syriac Alexander Legend and the hadiths: the sun enters the sea/spring, then bows/prostrates before God.
I was with the Prophet ﷺ riding on a donkey, and it had a saddlecloth or a blanket on it. He said to me, "O Abu Dhar, do you know where this (the sun) sets?" I said, "Allah and His Messenger know best." He said, "Indeed, it sets in a hot spring and travels until it prostrates itself to its Lord beneath the Throne. When its time to rise comes, Allah gives it permission to rise, and it rises. And when it is time for it to set from where it rises, it is prevented and it utters: 'O Lord! My course is far, so give me permission.' So, Allah lets it rise from the place where it sets. That is the time when the soul's faith will not benefit it." Musnad Ahmed 21459 Sunan Abu Dawud 4002 Sahih Bukhari 3199

Other Problems in Surah Al-Kahf: Gog and Magog and Seven Sleepers
Surah Al-Kahf tells two stories that were circulating:
Gog and Magog
Dhul Qarnayn built an iron and copper wall between two mountains to seal off the tribes of Gog and Magog until doomsday. This wall is nowhere to be found.
"Then he followed a road Till, when he came between the two mountains, he found upon their hither side a folk that scarce could understand a saying. They said: O Dhu'l-Qarneyn! Lo! Gog and Magog are spoiling the land. So may we pay thee tribute on condition that thou set a barrier between us and them? He said: That wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. Give me pieces of iron - till, when he had levelled up (the gap) between the cliffs, he said: Blow! - till, when he had made it a fire, he said: Bring me molten copper to pour thereon. And (Gog and Magog) were not able to surmount, nor could they pierce (it). He said: This is a mercy from my Lord; but when the promise of my Lord cometh to pass, He will lay it low, for the promise of my Lord is true. And on that day We shall let some of them surge against others, and the Trumpet will be blown. Then We shall gather them together in one gathering." Quran 18:92-99
Also in Syriac Alexander Legend
"He said to them, 'Who are their kings?' The old men said: 'Gog and Magog' ... Let us make a gate of brass and close up this breach… Alexander commanded… workers in iron ... workers in brass… they put down brass and iron… then they brought it and made a gate...when the world shall come to an end by the command of God ... The Lord shall send His sign from heaven… and it shall be destroyed and fall." Budge, Syriac Alexander Legend, p. 150-153
Authentic hadiths about Gog and Magog:
Gog and Magog Dig Every Day and Will Break Through When They Say “Inshallah”
"It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said: Gog and Magog people dig every day until, when they can almost see the rays of the sun, the one in charge of them says: 'Go back and we will dig it tomorrow.' Then Allah puts it back, stronger than it was before. (This will continue) until, when their time has come, and Allah wants to send them against the people, they will dig until they can almost see the rays of the sun, then the one who is in charge of them will say: 'Go back, and we will dig it tomorrow if Allah wills.' So they will say: 'If Allah wills.' Then they will come back to it and it will be as they left it. So they will dig and will come out to the people, and they will drink all the water. The people will fortify themselves against them in their fortresses. They will shoot their arrows towards the sky and they will come back with blood on them, and they will say: 'We have defeated the people of earth and dominated the people of heaven.' Then Allah will send a worm in the napes of their necks and will kill them thereby.'" The Messenger of Allah (ﷺ) said: "By the One in Whose Hand is my soul, the beasts of the earth will grow fat on their flesh." Sunan Ibn Majah 4080
999 Gog and Magog for Every 1 Muslim in Hell
The Prophet (ﷺ) said, "On the day of Resurrection Allah will say, 'O Adam!' Adam will reply, 'Labbaik our Lord, and Sa`daik' Then there will be a loud call (saying), Allah orders you to take from among your offspring a mission for the (Hell) Fire.' Adam will say, 'O Lord! Who are the mission for the (Hell) Fire?' Allah will say, 'Out of each thousand, take out 999.' At that time every pregnant female shall drop her load (have a miscarriage) and a child will have grey hair. And you shall see mankind as in a drunken state, yet not drunk, but severe will be the torment of Allah." (22.2) (When the Prophet (ﷺ) mentioned this), the people were so distressed (and afraid) that their faces got changed (in color) whereupon the Prophet (ﷺ) said, "From Gog and Magog nine-hundred ninety-nine [999] will be taken out and one [1] from you. You Muslims (compared to the large number of other people) will be like a black hair on the side of a white ox, or a white hair on the side of a black ox, and I hope that you will be onefourth of the people of Paradise." On that, we said, "Allahu-Akbar!" Then he said, "I hope that you will be) one-third of the people of Paradise." We again said, "Allahu-Akbar!" Then he said, "(I hope that you will be) one-half of the people of Paradise." So we said, Allahu Akbar." Sahih al-Bukhari 4741
Seven Sleepers
Surah Al-Kahf opens with the story of young monotheists who escape persecution and fall asleep in a cave for years but says only Allah and a few others know their number:
"When the young men fled for refuge to the Cave ... We sealed up their hearing in the Cave And afterward We raised them up ... (Some) will say: They were three, their dog the fourth, and (some) say: Five, their dog the sixth, guessing at random; and (some) say: Seven, and their dog the eighth. Say (O Muhammad): My Lord is Best Aware of their number. None knoweth them save a few." Quran 18:10-22
A Christian legend predating the Quran tells the same story but with these details: seven Christian sleepers flee Roman persecution, sleep for centuries and wake to find the Roman Empire had become Christian:
"seven sleeping brothers, and their puppy Viricanus at their feet" Martyrologium Hieronymianum (518-540 AD)
"During the time of the Emperor Decius, when a persecution was conducted upon Christians, seven men were arrested… shut themselves up in a single cave… collapsed on the ground and fell asleep… the Lord sent into the seven men the spirit of life and they arose… the boy saw the seal of the glorious cross over the gate of the city… he was amazed" Gregory of Tours (580-594 AD), pg 6-7

One-Liners
- The Sequencing Problem: You can't reach the setting place of the sun and then find it setting in a muddy spring.
- The Direction Cop-Out: West is a direction, not a destination. If the sun sets in the west from everywhere on Earth, how can you reach (balagha) its setting place?
- The Vocabulary Check: When have you ever described the ocean as a black muddy spring?
- The Perspective Trap: Springs are small and don't have horizons like oceans. You look down at a spring and can see its edges. The sun can't appear to set into a spring.
