The heavens and the cosmos
السماوات والعالمون والعرش والكرسي
The word samāʾ (sky, heaven) occurs 310 times; seven verses name the seven heavens outright. This study gathers what the Quran says about the heavens, the ʿālamīn (“worlds”), the Throne (ʿArsh) and the Footstool (Kursī), with the explanations of the classical commentators.
Including related themes: 165 verses across 59 surahs (shown in the chart below).
All figures are computed from the Quranic Arabic Corpus ontology and the Quran 360 theme index.

The QAC ontology has no separate concept for the sky, so this study counts words with the Corpus morphology. The noun samāʾ (sky, heaven; singular and plural together) occurs 310 times in 297 verses across 76 surahs, and in 222 verses the heavens and the earth are mentioned together. Our theme index adds the verses on the creation of the heavens and the earth, the six days, the seven heavens and the end of the world, so the study covers 165 verses in 59 surahs.
The Quran describes the heavens as seven, made in layers (ṭibāqan, 67:3; 71:15), raised without pillars that we can see (13:2), and the nearest heaven adorned with lamps (41:12; 67:5). Above them is the Throne (al-ʿArsh): the ontology tags Allah's Throne in 22 verses across 20 surahs. The Kursī is named once, in Āyat al-Kursī: “His Kursī extends over the heavens and the earth” (2:255).
The Quran's first praise is to Allah, “Lord of the worlds” (rabb al-ʿālamīn, 1:2). The word ʿālamīn occurs 73 times, and the full phrase rabb al-ʿālamīn 42 times. Ibn Kathir explains ʿālamīn as the plural of ʿālam: everything that exists other than Allah, every kind of creation. He also reports narrower views, discussed below.
This study describes what the verses say and how the classical commentators explained them. It makes no claims of “scientific miracles”; where modern readings exist, they are labelled as such.
Key facts
The noun samāʾ (sky, heaven) occurs 310 times in 297 verses across 76 surahs.
7 verses name “seven heavens” with both words: 2:29, 17:44, 23:86, 41:12, 65:12, 67:3, 71:15.
Ibn Kathir explains “seven paths” (23:17) and “seven strong ones” (78:12) as the seven heavens.
The heavens and the earth are mentioned together in 222 verses.
ʿĀlamīn occurs 73 times in 30 surahs; the phrase rabb al-ʿālamīn (“Lord of the worlds”) occurs 42 times, first in 1:2.
Ibn Kathir: the ʿālamīn are everything other than Allah, every kind of creation. He also reports narrower views (the jinn and mankind; or all beings with reason).
ʿArsh occurs 29 times. The ontology tags Allah's Throne in 22 verses across 20 surahs; in 8 verses the word means another throne or a roof.
Kursī occurs twice: Allah's Kursī in 2:255 and Sulaymān's chair in 38:34.
7 verses say creation took six days. Al-Ṭabarī records that some took each day as a thousand years (22:47), others as ordinary days.
On 51:47 scholars differ: al-Ṭabarī reads mūsiʿūn as “vast in power”; Muhammad Asad, a modern translator, as “steadily expanding it”.
The seven heavens
Seven verses use the words “seven” and “heaven(s)” together: Allah “turned to the sky and made them seven heavens” (2:29); the seven heavens and the earth glorify Him (17:44); He is “Lord of the seven heavens” (23:86); He completed them as seven heavens in two days (41:12); He created seven heavens “and of the earth the like of them” (65:12); and “seven heavens in layers” (67:3; 71:15). Two more verses speak of “seven paths above you” (23:17) and “seven strong ones” built above us (78:12); Ibn Kathir explains both as the seven heavens.
On ṭibāqan (67:3, 71:15) the commentators explain: one above another. 65:12 adds that the earth too has “the like of them”, and the commentators discuss what this means.
Lord of the worlds (ʿālamīn)
Al-ʿālamīn is the last word of 1:2 and occurs 73 times in 30 surahs. In Surah al-Shuʿarāʾ, prophet after prophet says: “My reward is only from the Lord of the worlds” (26:109, 26:127, 26:145, 26:164, 26:180).
What are the ʿālamīn? Ibn Kathir, on 1:2, explains ʿālam as everything that exists other than Allah, and ʿālamīn as all its kinds: in the heavens, on land and in the sea. He also reports narrower views: from Ibn ʿAbbās, “the jinn and mankind”; and from al-Farrāʾ and Abū ʿUbayda, the beings that have reason (humans, jinn, angels and devils). In some verses the word clearly means people, for example Maryam “chosen above the women of the worlds” (3:42), and the Children of Israel preferred “over the worlds” of their time (2:47).
The Throne (ʿArsh) and the Kursī
The word ʿarsh occurs 29 times. The ontology tags 22 verses as Allah's Throne. Seven of them say “then He rose over the Throne” after the creation of the heavens and the earth (7:54; 10:3; 13:2; 20:5; 25:59; 32:4; 57:4). Angels carry the Throne and glorify around it (40:7; 69:17). In 8 verses the same word means something else: the throne of Yūsuf's parents (12:100), the Queen of Sheba's throne (27:23, 27:38, 27:41, 27:42), and the roofs of ruined towns or trellised vines (2:259, 18:42, 22:45).
The Kursī is named twice. In 2:255 it is Allah's: “His Kursī extends over the heavens and the earth.” In 38:34 it is the chair of Sulaymān. The ontology files 2:255 under the Throne. Scholars differ on the Kursī: Ibn Kathir reports from Ibn ʿAbbās that it is distinct from the Throne, which is far greater, while al-Ṭabarī records another report from Ibn ʿAbbās that “His Kursī” means His knowledge.
Creation in six days
Seven verses say the heavens and the earth were created “in six days” (7:54; 10:3; 11:7; 25:59; 32:4; 50:38; 57:4). Al-Ṭabarī records that some early authorities took each “day” as a thousand years (compare 22:47), and others as ordinary days; the text does not specify. Surah Fuṣṣilat gives the order in more detail: the earth in two days, its provisions completing four, and the seven heavens in two (41:9-12). Ibn Kathir explains how this agrees with the six days.
Joined, then parted; smoke; built with might
“The heavens and the earth were joined (ratq), then We parted them (fatq)” (21:30). Al-Ṭabarī records several classical readings: they were one and were parted by the air; each was a single layer made into seven; or the sky was closed to rain and the earth to plants, then opened. Some modern writers link the verse to modern cosmology; that is a later reading, not the classical explanation.
Allah “turned to the heaven while it was smoke” (41:11); Ibn Kathir explains the smoke as vapour that rose from the water when the earth was created. “We built the heaven with might, and We are mūsiʿūn” (51:47): al-Ṭabarī explains mūsiʿūn as “possessing vastness (of power)”; Muhammad Asad, a modern translator, renders it “We are steadily expanding it”. Scholars differ.
A roof raised and guarded
The sky is “a canopy” (2:22) and “a protected roof” (21:32). Allah raised the heavens “without pillars that you see” (13:2; 31:10); Ibn Kathir reports two readings: there are no pillars at all, or there are pillars that you cannot see. The nearest heaven is adorned with lamps and guarded (41:12; 67:5). Ibn Kathir explains al-Bayt al-Maʿmūr (52:4) as a House in the seventh heaven visited every day by angels. At the end of the world the sky will split open (82:1; 84:1) and be rolled up like a scroll (21:104).

For reflection and discussion
Every day in Salah we say “Lord of the worlds” (1:2). After learning Ibn Kathir's explanation, what “worlds” come to mind, and how does this change the way you read al-Fātiḥa?
