What Does the Quran Say About the Shape of the Earth?
Modern Muslim apologists frequently claim that the Quran contains miraculous scientific knowledge, including foreknowledge that the earth is spherical. This claim is central to the "scientific miracles of the Quran" narrative that has become popular in dawah (Islamic evangelism) circles since the 1970s. However, when we examine the actual Arabic text of the Quran — along with how the earliest and most authoritative Muslim scholars understood these verses — a very different picture emerges. The Quran repeatedly describes the earth as flat, spread out, and extended like a carpet or bed, and classical Islamic scholars overwhelmingly understood these descriptions literally.
The Key Verses: Earth "Spread Out" and "Flattened"
Quran 71:19 — "Made the Earth a Carpet"
"And Allah has made for you the earth an expanse [bisatan]." — Quran 71:19
The Arabic word bisatan (بساطا) literally means "a carpet" or "a thing spread out." This is the same word used in Arabic for a rug or mat that is laid flat on the ground. The imagery is unmistakable: the earth is compared to a flat surface that has been unrolled for human habitation.
Quran 78:6 — "Made the Earth a Bed"
"Have We not made the earth a resting place [mihadan]?" — Quran 78:6
The word mihadan (مهادا) means "a bed," "a cradle," or "an expanse." It derives from the root m-h-d, meaning to level, flatten, or make smooth. A bed or cradle is, by definition, a flat surface. No one describes a sphere as a "bed."
Quran 88:20 — "How the Earth Is Spread Out"
"And at the earth — how it is spread out [sutihat]?" — Quran 88:20
The verb sutihat (سُطِحَت) comes from the root s-t-h, meaning "to flatten" or "to make level." The noun sath (سطح) means "a flat surface" or "a roof." This verse explicitly invites the reader to observe how the earth has been made flat — presenting it as evidence of Allah's creative power. The unmistakable implication is that a flat earth is a feature, not a bug; it is a sign of divine design.
Quran 91:6 — "The Earth and How It Was Spread"
"And [by] the earth and He who spread it [tahaha]." — Quran 91:6
The verb tahaha (طحاها) comes from the root t-h-w, meaning "to spread out" or "to extend." Al-Tabari, in his tafsir, explained this as meaning "He extended it from all sides." The imagery is consistently that of a surface being stretched flat, not of a sphere.
Quran 15:19 — "We Spread the Earth"
"And the earth — We have spread it [madadnaha] and cast therein firmly set mountains and caused to grow therein [something] of every well-balanced thing." — Quran 15:19
The verb madadnaha (مددناها) means "We stretched it out" or "We extended it." This same root (m-d-d) is used throughout the Quran to describe the spreading or extending of flat surfaces.
Quran 20:53 — "Made the Earth a Bed"
"[He] who made for you the earth a bed and made for you therein paths that you may be guided." — Quran 20:53
Quran 51:48 — "We Spread It Excellently"
"And the earth — We have spread it. How excellent are those who spread [it]!" — Quran 51:48
The verb farashna (فرشنا) means "We spread it out" or "We furnished it," from the same root as firash (فراش), meaning a carpet, mattress, or flat covering. Again, the earth is likened to a flat surface spread out for use.
The Dahaha Debate: Did the Quran Say "Egg-Shaped"?
The single most popular counter-argument from Muslim apologists centers on Quran 79:30:
"And after that He spread the earth [dahaha]." — Quran 79:30
Apologists, most notably the popular speaker Zakir Naik, have claimed that the Arabic word dahaha (دحاها) means "made it egg-shaped," supposedly from the word dahya (دحية) or udhhiyya, which they claim means "ostrich egg." This, they argue, proves the Quran knew the earth was an oblate spheroid (slightly flattened at the poles, like an egg).
This argument is linguistically and historically indefensible:
1. The Root Meaning
The verb dahaha comes from the root d-h-w (دحو). The primary meaning in classical Arabic dictionaries is "to spread out," "to extend," or "to throw" (as in rolling or pushing something along a flat surface). Lane's Lexicon, the most authoritative classical Arabic-English dictionary, defines daha as: "He spread it; spread it out or forth; expanded it." There is no mention of eggs or egg-shapes in the primary definition.
2. The Ostrich Egg Connection Is Fabricated
The word for an ostrich egg in Arabic is udhhiyya (أُدْحِيّة) or udhuww — and it does not refer to the shape of the egg but to the nest where the ostrich deposits its eggs. An ostrich nest is a depression in the ground — a flat, spread-out area scraped in the sand. So even if one connects dahaha to ostrich nests, the meaning is "flattened out," not "egg-shaped."
3. No Classical Scholar Understood It This Way
Not a single classical Quranic commentator interpreted dahaha as meaning "egg-shaped." Al-Tabari, Ibn Kathir, al-Qurtubi, al-Jalalayn, al-Zamakhshari, and al-Baydawi all interpreted the word as meaning "spread out" or "extended." The "egg-shaped" interpretation was invented in the 20th century for apologetic purposes.
4. Ostrich Eggs Are Not Oblate Spheroids
Even if dahaha did mean "egg-shaped" (which it does not), ostrich eggs are elliptical, not oblate spheroids. The earth is slightly flattened at the poles and bulging at the equator — the opposite of an egg shape. The analogy fails on its own terms.
Mountains as Pegs: Flat-Earth Cosmology
The Quran's description of mountains further supports a flat-earth cosmology:
"And the mountains as pegs [awtadan]?" — Quran 78:7
"And He has cast into the earth firmly set mountains, lest it should shift with you." — Quran 16:15
The idea that mountains are "pegs" or "stakes" driven into the earth to prevent it from shaking is consistent with a flat-earth model — imagine tent pegs holding down a carpet to prevent it from moving. This is not how geology works. Mountains are not stabilizers; they are the result of tectonic plate collisions. Earthquakes are most common precisely in mountainous regions where plates meet. For a detailed analysis, see our article on mountains as pegs: the Quranic error.
What Classical Scholars Actually Believed
Al-Tabari (d. 923 CE)
Muhammad ibn Jarir al-Tabari, the most authoritative early Quranic commentator, interpreted the relevant verses as describing a flat earth. In his commentary on Quran 88:20, he wrote that sutihat means "spread out" and "extended," indicating a flat surface. His cosmology, consistent with the Quran, described a flat earth beneath layered heavens.
Ibn Kathir (d. 1373 CE)
Ibn Kathir likewise interpreted these verses in their plain meaning — the earth was spread out flat for human habitation. He did not suggest a spherical earth in his commentary on any of these verses.
Al-Suyuti (d. 1505 CE)
Al-Suyuti, in Al-Itqan fi Ulum al-Quran, discussed the earth's description without contradicting the flat-earth reading. His focus was on cataloging Quranic sciences, and he treated the earth's extension as a divine favor.
Notable Exceptions
It is fair to note that some medieval Muslim scholars did accept a spherical earth. Ibn Hazm (d. 1064 CE), Ibn Taymiyyah (d. 1328 CE), and a few others accepted the earth's roundness based on Greek scientific knowledge that had been translated into Arabic during the Abbasid era. However, critically, these scholars did not derive this knowledge from the Quran. They learned it from Greek astronomy (particularly Ptolemy) and then attempted to reconcile it with the Quranic text. Ibn Taymiyyah, for instance, stated there was scholarly consensus (ijma) that the earth is round — but his evidence was Greek science, not Quranic verses.
This is an important distinction: the fact that some Muslim scholars knew the earth was round does not mean the Quran teaches it. They knew it despite the Quran's language, not because of it.
Modern Apologetic Attempts
The "Phenomenological Language" Defense
Some modern apologists argue that the Quran uses "phenomenological language" — describing the earth as it appears to a human observer, not as it literally is. Just as we say "sunrise" without meaning the sun literally rises, the Quran says the earth is "spread out" without meaning it is literally flat.
This argument has several problems:
- If the Quran's descriptions are merely phenomenological, they cannot also be "scientific miracles." You cannot claim the Quran reveals scientific truths while simultaneously excusing its inaccuracies as figurative language.
- The Quran presents these descriptions as evidence of Allah's power — "look at how the earth was spread out." If the spreading is not literal, the argument collapses.
- The same apologists who dismiss flat-earth language as phenomenological will insist that other verses (about embryology, water barriers, etc.) are literal scientific statements. The inconsistency is obvious.
The "Multiple Meanings" Defense
Some argue that Arabic words can have multiple meanings, and we should choose the meaning that aligns with modern science. But this is eisegesis (reading meaning into the text) rather than exegesis (deriving meaning from the text). Classical scholars, who understood Arabic far better than modern apologists, consistently chose the "spread out flat" meaning. The "egg-shaped" meaning was not proposed until the 20th century, after the earth's shape was already well established by secular science.
The Broader Pattern: Quranic Cosmology
The flat-earth verses do not exist in isolation. They are part of a consistent cosmological picture in the Quran that includes:
- The sky as a solid ceiling: "And We made the sky a protected ceiling" (Quran 21:32). See our article on the sky as a solid ceiling.
- Seven layered heavens: "It is He who created for you all of that which is on the earth. Then He directed Himself to the heaven and made them seven heavens" (Quran 2:29). See the seven heavens in Islamic cosmology.
- Stars as missiles: "And We have certainly beautified the nearest heaven with stars and have made them as missiles to drive away the devils" (Quran 67:5). See stars as missiles against devils.
- The sun setting in a muddy spring: "Until, when he reached the setting of the sun, he found it setting in a spring of dark mud" (Quran 18:86). See the sun sets in a muddy spring.
Taken together, these verses describe a pre-scientific, flat-earth cosmology common in the 7th-century Near East: a flat earth covered by solid, domed heavens, with stars as small objects embedded in the nearest heaven, and the sun as a relatively small body that literally sets in a pool of water. This is not miraculous foreknowledge — it is a reflection of the cosmological understanding of Muhammad's time.
Why This Matters
The flat-earth question is not merely academic. It goes to the heart of the Quran's claim to be the perfect, uncreated word of an omniscient God. If the Quran accurately described the earth's shape, it could be evidence of divine authorship. But since the Quran consistently describes the earth in terms consistent with 7th-century flat-earth understanding — and since the "egg-shaped" counter-argument is linguistically indefensible — the evidence points in the opposite direction. The Quran's cosmology is exactly what we would expect from a 7th-century Arabian text, not from an omniscient creator.
