The Cosmology the Quran Mapped Fourteen Hundred Years Before Modern Physics Had a Word For It
Seven Heavens, and of the Earth Their Like
There is a verse the Interpreter of the Qur’an would not unfold in public.
Abdullah ibn Abbas — cousin of the Prophet ﷺ, the one for whom he prayed, “O Allah, deepen his understanding of the religion and teach him the interpretation” — carried the title Tarjumān al-Qur’an, the Interpreter of the Qur’an. He explained what others could not. On this verse he stopped.
اللَّهُ الَّذِي خَلَقَ سَبْعَ سَمَاوَاتٍ وَمِنَ الْأَرْضِ مِثْلَهُنَّ ۖ يَتَنَزَّلُ الْأَمْرُ بَيْنَهُنَّ
“Allah is the One who created seven heavens, and of the earth their like. The Command descends between them.” — At-Talaq 65:12
When a man pressed him on its meaning, al-Ṭabarī records the reply through Mujāhid: “Were I to tell you its interpretation, you would disbelieve — and your disbelief would be your denial of it.” In another route, his answer was a question: “What would secure you against disbelief, were I to inform you?”
He was not protecting a secret. He was measuring his listeners against a meaning the verse holds in plain Arabic, and finding them short of it.
The Word That Carries It
The weight rests on one word: mithlahunna. “Their like.”
The pronoun is feminine plural, and it reaches back to sabʿa samāwāt — the seven heavens. The construction is not loose. The earth is given their like — like the heavens, in number and in kind. Not one earth beneath seven skies, but earths answering to heavens, the lower order mirroring the upper. And between the two, yatanazzalu al-amr — the Command comes down, governing the whole structure as it descends.
The grammar admits no argument. What the seven earths are — that is where the scholars worked, and where they divided. The sentence is settled; its cosmos is the open country. This is the distinction that matters, and most readers collapse it: the language is fixed, the referent is vast.
What Ibn Abbas Said When He Spoke
He did not always withhold. In the narration carried by al-Ṭabarī in his Jāmiʿ al-Bayān, by al-Bayhaqī in al-Asmāʾ wa al-Ṣifāt, and by al-Ḥākim in al-Mustadrak, he gave the interpretation:
“In every one of those earths there is an Adam like your Adam, a Nūḥ like your Nūḥ, an Ibrāhīm like your Ibrāhīm, an ʿĪsā like your ʿĪsā.”
Earths answering to earths. In each, a humanity. In each, the prophetic line. In each, the Command descending the same vertical axis it descends here. The structure of revelation, repeated across the structure of creation.
I will be exact about the standing of this report, because precision is the whole strength of the position. The narration is mawqūf — it rests with Ibn Abbas, not raised to the Prophet ﷺ. On its principal route, al-Bayhaqī gave a verdict worth quoting in full: the chain is ṣaḥīḥ and shādhdh at once — sound, yet singular, since Abū al-Ḍuḥā transmits it with no one to corroborate him. Sound in its men, anomalous in standing alone.
That places it precisely. It is not invention. It is not established law. It is the kind of report the tradition handles by the Prophet’s own instruction regarding such material: neither believe it nor deny it. You may carry it. You do not build on it alone.
And the position does not need to. The interpretation is illustration. The verse is the claim. Remove the narration entirely and mithlahunna still stands in the muṣḥaf — seven heavens, and of the earth their like, the Command between them. Ibn Abbas only said aloud what the word already holds.
The Readings That Endured
The classical commentators left three readings of the verse, and the scale survives all three.
The first reads it as worlds — earths set apart, the distances between them vast, each with its own creation and command. Qurṭubī records this openly, and the Akbarian school took it furthest. The parallel-Adams report belongs here.
The second reads it as earths layered within our own, seven strata, joined to the seven-earths report in Ṣaḥīḥ al-Bukhārī. Ibn Kathīr and the body of the exegetes settled here.
The third reads it as orders of being — seven ascending strata of existence — in the language of the Sufis.
No reading shrinks the verse to the small sky the seventh-century eye could see. That is the point to hold. Whatever mithlahunna finally means, it was never the single bounded world the surrounding cultures assumed.
The Lord of the Worlds
The opening of the Book names Him rabb al-ʿālamīn — Lord of the worlds. The plural is not ornament. Ibn Abbas, glossing it in al-Ṭabarī, read al-ʿālamīn as the worlds known and unknown.
Consider what follows from a Lord of worlds known and unknown sending a single Book. Such a revelation cannot name every particular, because particulars belong to single worlds — this Pharaoh, that year, the count of those in the cave. It states instead what holds across worlds and leaves open what need not be the same in each. It fixes the architecture and declines the blueprint.
At-Talaq 65:12 is that method made visible. It commits to the structure — heavens and earths in mirrored plurality, one Command governing all of it — and withholds the survey. How many earths in the fullest sense, of what nature, peopled how: the verse does not say, and its Interpreter would not say, because the saying was not yet receivable.
This is why Ibn Abbas could hold back without evasion. The verse was built to be larger than its first audience. It was built to be larger than ours.
Where the Modern Mind Arrives
The cosmology of the seventh century — inherited Greek, Persian, the sky over Arabia — was singular and closed. One world, one vault above it. The Qur’an spoke instead of seven heavens, of earths that are their like, of a Command moving between, and its earliest reader took the worlds to run past the edge of the known.
Theoretical physics has spent its last seventy years unable to keep the cosmos singular — through Everett’s branching worlds, through inflationary cosmology, through the landscape of string theory. None of this is photographed; a plurality of worlds is not the kind of thing an instrument retrieves. So this is no claim that a telescope has caught up to a verse. The verse needs no such rescue.
The claim is cleaner and harder to answer. The Qur’an did not lock itself into the one small world its century could see. Where every cosmology around it closed the cosmos, the Book left it open — and the openness was deliberate, the work of a Lord who knew the measure of what He had made and declined to hand a seventh-century audience a number they would only have used to make Him small.
Seven heavens. And of the earth their like. The Command descending between them.
The Interpreter saw how far it reached, and chose his silence. The verse has been waiting in the open the whole time.
Wa-Llāhu aʿlam.
