Dhul-Qarnayn:
The Journeys Beyond the Known

From the horizons of the sun to the ethics of power. A journey through revelation, astronomy and the responsibility to protect.

Hero image: Webb’s Cosmic Cliffs · NASA, ESA, CSA, STScI. An astronomical image used thematically, not an identified destination of Dhul-Qarnayn.

Three journeys · One ethical thread

What does power do when it reaches a new horizon?

The account follows the setting horizon, the rising horizon and a community between two barriers. Capacity and exploration are repeatedly brought into relation with judgment, vulnerability, cooperation and mercy.

Textual narrative

01 · The setting horizon

18:85–88 presents a solar horizon, a people and a decision about conduct. The scene’s moral question is how authority distinguishes wrongdoing from righteous action.

Text & interpretation

02 · The rising horizon

18:89–91 presents a people exposed to the sun. A cosmic reading compares rising with the birth of light; a geographical reading concerns an eastern journey.

Protection & cooperation

03 · Between two barriers

18:92–98 moves to communication, destructive incursions and a cooperative construction project. Its closing statement attributes the work to mercy.

The distinction guiding this page: the Qur’anic account, classical tafsir, modern space-travel proposals, abstract reflection and observed astronomy each have their own kind of evidence. Connections are explored without presenting them as identical claims.

Primary source · Every verse

The narrative in full

Arabic text and Pickthall’s English translation (1930), with original explanatory notes. The core story is 18:83–98; 18:99–101 is included to preserve its immediate eschatological continuation.

18:83 · A question and a remembrance
وَيَسْـَٔلُونَكَ عَن ذِى ٱلْقَرْنَيْنِ ۖ قُلْ سَأَتْلُوا۟ عَلَيْكُم مِّنْهُ ذِكْرًا

They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance of him.

The account begins with a question about Dhul-Qarnayn. The answer offers a remembrance of him, not a complete biography or a dated map.

18:84 · Capacity and means
إِنَّا مَكَّنَّا لَهُۥ فِى ٱلْأَرْضِ وَءَاتَيْنَٰهُ مِن كُلِّ شَىْءٍۢ سَبَبًۭا

Lo! We made him strong in the land and gave him unto every thing a road.

Allah grants him establishment in the land and means for his undertakings. The term sabab can refer to a means or route; a specific vehicle or spacecraft is not named.

Compare translations ↗
18:85 · Following a route
فَأَتْبَعَ سَبَبًا

And he followed a road

The first journey begins by using the means available to him. Action follows capacity; the repeated phrase links all three journeys.

18:86 · The setting horizon
حَتَّىٰٓ إِذَا بَلَغَ مَغْرِبَ ٱلشَّمْسِ وَجَدَهَا تَغْرُبُ فِى عَيْنٍ حَمِئَةٍۢ وَوَجَدَ عِندَهَا قَوْمًۭا ۗ قُلْنَا يَٰذَا ٱلْقَرْنَيْنِ إِمَّآ أَن تُعَذِّبَ وَإِمَّآ أَن تَتَّخِذَ فِيهِمْ حُسْنًۭا

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 reaches the setting place of the sun and finds it setting in a murky spring, with people nearby. Ibn Kathir explains the scene through the traveller’s view of the western horizon. A black-hole interpretation is a modern proposal, not a term used in the verse.

18:87 · Accountability for wrongdoing
قَالَ أَمَّا مَن ظَلَمَ فَسَوْفَ نُعَذِّبُهُۥ ثُمَّ يُرَدُّ إِلَىٰ رَبِّهِۦ فَيُعَذِّبُهُۥ عَذَابًۭا نُّكْرًۭا

He said: As for him who doeth wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with awful punishment!

Dhul-Qarnayn connects wrongdoing with earthly judgment and a return to the Lord. His authority is not presented as freedom from accountability.

Compare translations ↗
18:88 · Faith, good action and ease
وَأَمَّا مَنْ ءَامَنَ وَعَمِلَ صَٰلِحًۭا فَلَهُۥ جَزَآءً ٱلْحُسْنَىٰ ۖ وَسَنَقُولُ لَهُۥ مِنْ أَمْرِنَا يُسْرًۭا

But as for him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command.

Belief and righteous action receive a good reward and an easier response. The passage joins power with a distinction between conduct and its consequences.

Compare translations ↗
18:89 · Another route
ثُمَّ أَتْبَعَ سَبَبًا

Then he followed a road

A second journey follows. The text’s order is the setting horizon first, then the rising horizon.

Compare translations ↗
18:90 · The rising horizon
حَتَّىٰٓ إِذَا بَلَغَ مَطْلِعَ ٱلشَّمْسِ وَجَدَهَا تَطْلُعُ عَلَىٰ قَوْمٍۢ لَّمْ نَجْعَل لَّهُم مِّن دُونِهَا سِتْرًۭا

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.

He finds people for whom no shelter from the sun has been provided. The narrative describes a people and their exposure; the interpretation as a stellar nursery introduces an astronomical analogy beyond the explicit wording.

Compare translations ↗
18:91 · Divine knowledge encompasses the journey
كَذَٰلِكَ وَقَدْ أَحَطْنَا بِمَا لَدَيْهِ خُبْرًۭا

So (it was). And We knew all concerning him.

The account emphasizes Allah’s encompassing knowledge of what accompanied Dhul-Qarnayn. It does not give readers every detail of his location or equipment.

18:92 · A third route
ثُمَّ أَتْبَعَ سَبَبًا

Then he followed a road

The next movement again follows a means or route. Its compass bearing is not explicitly supplied.

18:93 · Between the two barriers
حَتَّىٰٓ إِذَا بَلَغَ بَيْنَ ٱلسَّدَّيْنِ وَجَدَ مِن دُونِهِمَا قَوْمًۭا لَّا يَكَادُونَ يَفْقَهُونَ قَوْلًۭا

Till, when he came between the two mountains, he found upon their hither side a folk that scarce could understand a saying.

He arrives between two barriers and encounters people who scarcely understand speech. Classical commentary treats the setting as a pass between mountains. The scene centres a vulnerable community.

Compare translations ↗
18:94 · A request for protection
قَالُوا۟ يَٰذَا ٱلْقَرْنَيْنِ إِنَّ يَأْجُوجَ وَمَأْجُوجَ مُفْسِدُونَ فِى ٱلْأَرْضِ فَهَلْ نَجْعَلُ لَكَ خَرْجًا عَلَىٰٓ أَن تَجْعَلَ بَيْنَنَا وَبَيْنَهُمْ سَدًّۭا

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?

The people describe Ya’juj and Ma’juj as causing corruption in the land and offer payment for a barrier. The verse names the threat without identifying a present-day nation.

Compare translations ↗
18:95 · Cooperation instead of personal tribute
قَالَ مَا مَكَّنِّى فِيهِ رَبِّى خَيْرٌۭ فَأَعِينُونِى بِقُوَّةٍ أَجْعَلْ بَيْنَكُمْ وَبَيْنَهُمْ رَدْمًا

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.

Dhul-Qarnayn values what his Lord has granted above the offered payment and asks for assistance in strength. Protection becomes a cooperative undertaking.

18:96 · Iron, heat and molten material
ءَاتُونِى زُبَرَ ٱلْحَدِيدِ ۖ حَتَّىٰٓ إِذَا سَاوَىٰ بَيْنَ ٱلصَّدَفَيْنِ قَالَ ٱنفُخُوا۟ ۖ حَتَّىٰٓ إِذَا جَعَلَهُۥ نَارًۭا قَالَ ءَاتُونِىٓ أُفْرِغْ عَلَيْهِ قِطْرًۭا

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.

The work uses blocks of iron, fills the space between the mountain sides, involves blowing until the iron is fire-like, and adds qitr, traditionally understood as molten copper. The sequence is vivid but not a modern specification.

Compare translations ↗
18:97 · The barrier holds
فَمَا ٱسْطَٰعُوٓا۟ أَن يَظْهَرُوهُ وَمَا ٱسْتَطَٰعُوا۟ لَهُۥ نَقْبًۭا

And (Gog and Magog) were not able to surmount, nor could they pierce (it).

The opposing people can neither scale nor penetrate the barrier. The verse states the outcome without supplying dimensions, coordinates or a surviving archaeological identification.

18:98 · Mercy and a limit
قَالَ هَٰذَا رَحْمَةٌۭ مِّن رَّبِّى ۖ فَإِذَا جَآءَ وَعْدُ رَبِّى جَعَلَهُۥ دَكَّآءَ ۖ وَكَانَ وَعْدُ رَبِّى حَقًّۭا

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.

Dhul-Qarnayn credits his Lord’s mercy. The barrier is not eternal: the divine promise will bring its levelling. Achievement ends with humility.

18:99 · The transition to the final gathering
۞ وَتَرَكْنَا بَعْضَهُمْ يَوْمَئِذٍۢ يَمُوجُ فِى بَعْضٍۢ ۖ وَنُفِخَ فِى ٱلصُّورِ فَجَمَعْنَٰهُمْ جَمْعًۭا

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.

The account moves to a scene of surging crowds, the trumpet and gathering. Read this continuation with 18:98 rather than treating the engineering achievement as permanent.

18:100 · The unveiling of Hell
وَعَرَضْنَا جَهَنَّمَ يَوْمَئِذٍۢ لِّلْكَٰفِرِينَ عَرْضًا

On that day we shall present hell to the disbelievers, plain to view,

The eschatological sequence continues. The horizon of the narrative is now judgment, beyond the immediate political and geographical events.

18:101 · Perception and heedlessness
ٱلَّذِينَ كَانَتْ أَعْيُنُهُمْ فِى غِطَآءٍ عَن ذِكْرِى وَكَانُوا۟ لَا يَسْتَطِيعُونَ سَمْعًا

Those whose eyes were hoodwinked from My reminder, and who could not bear to hear.

The closing context concerns those whose eyes were veiled from remembrance and who could not bear to hear. The journey’s ethical frame extends beyond technology and exploration.

Journey one · A cosmic interpretive proposal

The setting horizon: stars at the edge of darkness

A dedicated exploration of the proposed association between the sun’s setting place and a star’s encounter with a black hole. The association is a modern interpretation; the astronomical processes can be studied independently.

NASA visualization of a star disrupted near a black hole
Illustration: stellar tidal disruption · NASA’s Goddard Space Flight Center. This is a model visualization, not a photograph of Dhul-Qarnayn’s destination.
Classical tafsir

The verse and the observer

The wording of 18:86 describes the setting sun and a murky spring, with people nearby. Ibn Kathir reads this as an apparent sunset at the sea horizon. This classical perspective does not identify the spring with a black hole.

Observed astrophysics

A star torn apart

A star passing sufficiently close to a massive black hole can be stretched and disrupted by unequal gravitational forces. Some material may return and accrete, while some may escape. This is a tidal disruption event.

Astronomical concept

Across an event horizon

The event horizon marks a boundary beyond which signals cannot reach distant observers. Light produced by hot material outside it can make the region bright. The black hole’s darkness and the surrounding glow should not be confused.

Our Sun and “other suns”: Sun-like stars may be involved in external black-hole encounters. This is different from our Sun becoming a black hole: its expected evolution ends in a white dwarf. There is no established evidence that our Sun is destined to fall into a black hole. In a cosmic interpretation, using “sun” to mean another star must be stated as an interpretive choice.

Journey two · Stellar nurseries

The rising horizon: new stars within nebulae

A cosmic reading associates the emergence of sunlight with stellar birth. Astronomy offers a vivid account of star-forming clouds; it does not by itself establish that 18:90 describes one.

Astronomy

A cloud gathers

Dense portions of cold molecular clouds can contract under gravity. Star formation depends on the physical conditions of the cloud; not every nebula forms stars.

Astronomy

A protostar emerges

A contracting core heats as it accumulates material. Young stars may remain hidden by dust, which makes infrared observations valuable. Disks and outflows reveal a developing stellar environment.

Astronomy

A star becomes established

When suitable conditions are reached, sustained hydrogen fusion supports a main-sequence star. Stellar birth is a physical process over extended timescales, not simply a sunrise observed on a planet.

Narrative context

The people exposed to the sun

18:90 also describes people without shelter from the sun. An interpretation should explain this detail rather than focusing only on the phrase about rising. The verse does not explicitly name a nebula or a protostar.

Interpretive proposal

The cosmic question

Could the rising horizon symbolize the origin of a new light, or could a modern reading posit a stellar nursery? The first is an abstract analogy; the second is a proposed physical identification requiring additional evidence.

Abstract & philosophical readings

Journeys beyond geography

These are original thematic readings for reflection. They add a philosophical layer while leaving the narrative and its people in place.

Editorial reflection

The setting: the limits of control

Sunset can become a metaphor for the passing of power and the end of certainty. The question is how a person acts when familiar measures of success no longer illuminate the whole situation.

Editorial reflection

The rising: renewal of understanding

Sunrise can symbolize the birth of insight and the beginning of responsibility. New knowledge requires care for those exposed to its effects, not merely admiration of the light.

Editorial reflection

The two barriers: constrained action

A narrow space can symbolize the conditions within which human beings must work. Wisdom combines awareness of limits with practical action inside them.

Editorial reflection

Gog and Magog: destructive excess

As a thematic analogy, the episode prompts reflection on uncontrolled appetite, violence and systems that destroy the conditions of shared life. It does not erase the named peoples or classify a living ethnic group.

Editorial reflection

Iron and molten material: strength and cohesion

Iron may metaphorically suggest discipline; the poured material may suggest connection and completion. These symbolic meanings are not metallurgical explanations of the verse.

Editorial reflection

Mercy: the measure of achievement

The completed work can be read as an ethical test of technology. Its value lies in protection and humility rather than a monument to the builder’s ego.

Journey three · Two barriers & one shared undertaking

Between the two barriers

The account moves from horizons to a community’s request. Classical tafsir reads the two barriers as mountains with a pass between them. No exact modern coordinates are stated in the passage.

18:93–95

Listen before building

The community is described through a difficulty in understanding speech. Yet a request is communicated and answered. Their vulnerability does not prevent them from becoming partners in the work.

18:94–95

Protection without tribute

They offer payment. Dhul-Qarnayn instead emphasizes what his Lord has already granted and asks for assistance in strength. Local contribution and capable leadership meet in a public purpose.

Construction element What the account states Research question
Topography A location between barriers and a gap between mountain sides. How do passes create routes and defensive bottlenecks?
Iron blocks Material brought together to fill the space. How would blocks, joints and supporting ground carry loads?
Heat and blowing The assembled work is heated until fire-like. How might air flow and heat distribution be understood historically?
Qitr Poured material, commonly interpreted as molten copper. What distinguishes a coating, fill and bond? The verse does not specify an alloy recipe.
Outcome The opposing people cannot climb or pierce it. What evidence would identify a real structure with this account?

Cosmic barrier proposal: some modern readings relocate the third journey beyond Earth. Ideas of habitat protection or boundaries between worlds remain speculative. The existence of magnetic fields, planetary rings or cosmic structures is not evidence that any one of them is this iron-and-qitr barrier.

Dedicated research dossier · Ya’juj & Ma’juj

Gog and Magog: text, tradition and open questions

Read the Qur’anic references first, then the hadith and historical arguments. A modern political resemblance cannot establish who the named peoples are.

Scripture

The Qur’anic account

18:94 describes destructive activity and a request for separation. 18:97–98 describes the barrier’s effectiveness and eventual levelling. 21:96–97 adds the release and the true promise.

Hadith

The hadith horizon

Sahih Muslim 2937a places Gog and Magog in an extended end-times account. Compare its details with the Qur’anic passages without silently moving every hadith detail into Al-Kahf.

Tafsir

Classical understanding

Ibn Kathir discusses the peoples as human descendants of Adam and the setting as a mountain pass. Later reports and popular retellings do not all carry the same evidential weight.

Historical question

Who were they?

Historical proposals require attention to dates, languages, geography and the transmission of names. Identification with a present-day nation or ethnicity is not established by the Qur’anic wording.

Archaeological question

Where is the barrier?

A defensive wall or mountain gate may be compared with the story, but resemblance alone does not prove identity. A proposal should account for materials, chronology and the entire narrative.

Eschatological question

When will the promise occur?

The passage supplies no modern calendar date. Date predictions or claims that a current event conclusively fulfils it add information beyond the cited verses.

A symbolic lens: the episode can prompt reflection on destructive systems and protective institutions. This is a contemporary analogy, not a declaration that a named population is inherently corrupt, or that the traditional account is only a psychological metaphor.

History & interpretation

Who is Dhul-Qarnayn?

The epithet commonly rendered “the two-horned one” has generated several historical proposals. The Qur’an does not give a personal name, dynasty or dated itinerary. The question remains an area of debate.

Comparative research

Alexander traditions

Some scholarship studies relationships with Alexander narratives and late-antique literature. Literary parallels and the identity of a historical person are related but distinct questions.

Historical debate

Cyrus and other proposals

Other readings propose Persian rulers or other figures. A title, image or political resemblance should be weighed against the passage’s broader details and independent historical sources.

Modern hypothesis

The space-travel proposal

İskender Türe’s book explores a cosmic reading. This page extends the comparison with stellar nurseries and black holes while retaining the proposal’s status as interpretation.

Academic dialogue & education

Turn curiosity into a research question

A rich interpretation should become more precise as it encounters evidence.

Language

Text laboratory

Compare the meanings of sabab, the solar horizons, the two barriers, radm and qitr. Ask which proposed meaning best explains the people, events and materials in context.

Science

Astronomy laboratory

Distinguish star birth, a daily sunrise, stellar evolution, black-hole formation and external tidal disruption. Identify which observations support each process.

Contemporary reflection

Ethics laboratory

Examine the relation between authority and service. What institutions today combine local participation, accountable technology and protection without making a community dependent on a ruler’s prestige?

From cosmic wonder to human responsibility

The journeys can widen our questions. The final measure of capability is what it protects, how it serves and whether it remembers its limits.
