The following compiles specific scientific, historical, biological, and logical criticisms of the Quran, organized by topic. Each point cites the relevant Quranic verses, supporting hadiths or classical tafsirs where applicable, and external lexical, academic, or scientific sources. The arguments rest on the plain meaning of the text, classical Arabic usage, and established empirical evidence.

1. Astronomy and Cosmology

The Quran repeatedly frames the sun and moon as “swimming” or “floating” in orbits, nearly always linked to the day/night cycle (36:37–40, 21:33, 13:2, 31:29, 91:1–2). Lane’s Lexicon (entry falak, pp. 2443–2444) confirms the orbital language. The sun is said to run to a “resting place” (36:38); Sahih Muslim 159a and Tafsir Ibn Kathir on 36:38 explain this as the sun prostrating nightly beneath God’s throne. In 2:258 Abraham states that God “brings” the sun from the east; Lane’s Lexicon (entry atā, p. 15) supports the active-transport sense.

Dhul-Qarnayn reaches the sun’s physical setting-place in a “muddy spring” and its rising-place (18:86, 18:90). Parallel material appears in the mid-6th-century Syriac Alexander Legend. Heaven and Earth are created in six ordinary “days” (yawm) (50:38, 41:9–10), paralleling Genesis 1:5 and Psalm 90:4 (see Decharneux, Creation and Contemplation, 2023, p. 165). Earth is completed before the heavens are formed into seven layers and adorned with stars (41:9–12, 2:29, 67:5); Tafsir Ibn Kathir on 2:29 and 79:30 (citing Ibn Abbas) and Lane’s Lexicon (entry fa, p. 2321) confirm the sequence.

Heaven and Earth were originally “joined” (ratqan) and then “clove asunder” (fataqnāhumā) (21:30); Lane’s Lexicon (entries ratqan p. 1027, fataqnāhumā p. 2331) and Mesopotamian creation motifs supply the background. Heaven is made from “smoke” (dukhān) (41:11–12); Lane’s Lexicon (p. 861) and parallels in Basil of Caesarea’s Hexaemeron and the Septuagint of Isaiah 51:6 are noted by Decharneux (2023, pp. 128–129).

Seven earths mirror the seven heavens (65:12); Sahih Bukhari 2454 treats them as stacked layers. Meteors function as missiles against eavesdropping jinn (37:6–10, 67:5, 15:16–18); Sahih Muslim 2229a and Jami` at-Tirmidhi 5:44:3224 elaborate the motif. Stars will “fall” or “scatter” (81:2, 82:2); classical tafsirs (Tanwîr al-Miqbâs, al-Jalalayn, Ibn Kathir) and Lane’s Lexicon (entry inkadarat, p. 2596) confirm the physical sense. The moon is split in two (54:1–3); Sahih Bukhari 4864 records the event as historical. The moon’s light is described with terms that classical dictionaries treat as inherent rather than reflected (10:5, 71:16); Lane’s Lexicon (entries muneer p. 2866, noor p. 2865) is decisive. Sun and moon are treated as comparable in size and distance (91:1–2, 36:40, 75:8–9).

The sky is a physical roof or tent, raised without pillars, strippable, foldable, and capable of falling in fragments (21:32, 52:5, 2:22, 40:64, 81:11, 52:44, 34:9). It contains gates through which rain and the Flood descend (54:11, 78:19) and “cords” (asbāb) that can be climbed (40:36–37, 38:10); see van Bladel, BSOAS 70 (2007). Night and day themselves move or orbit (7:54, 36:37, 39:5).

2. Evolution and Human Origins

The first human is created instantly from clay or mud (15:26, 55:14, 38:71–76). All humanity descends from a single created pair (4:1, 7:189, 32:7–8). Lane’s Lexicon (entry nasl, p. 3032) and population-genetic data (BioLogos summaries; Coyne, “How Big Was the Human Population Bottleneck?”) contradict a recent single-pair origin.

3. Genetics

No genetic signature of a Noah’s-Ark-scale human bottleneck exists (11:40). Ancient-DNA studies (Reich, Who We Are and How We Got Here, 2018; Hu et al., Science 2023) and bottleneck literature on other species show no matching global signature. Housing and gathering all species is practically impossible (Our World in Data species estimates; Mora et al., PLoS Biology 2011; Isaak, TalkOrigins flood problems).

4. Embryology and Reproduction

Semen originates “from between the backbone and the ribs” (86:6–7); Lane’s Lexicon (entry sulb, p. 1712). Progeny reside in the father’s “loins” before conception (7:172); Lane’s Lexicon (entry thahr, p. 197). The embryo forms directly from semen in a Hippocratic/Galenic sequence (23:13–14, 77:20–22). The female ovum is never mentioned. Humans pass through a literal “clot of congealed blood” (23:14, 96:2); Sahih Bukhari 3208 elaborates the 40-day stages. Sex is determined at the “clot” or “lump” stage rather than at conception (75:37–39); Sahih Bukhari 318. Bones form before flesh in strict sequence (23:14), matching Galen’s On Semen. All organisms are created “in pairs” (51:49, 36:36), ignoring parthenogenesis, asexual reproduction, and intersex conditions. Fetal development occurs within “three darknesses” (39:6), paralleling the Galenic three-membrane model (Decharneux 2023, pp. 95–102).

5. Other Biology

The heart, not the brain, is the seat of reasoning and understanding (22:46, 7:179, 17:46). Milk forms between “excretions and blood” and is universally pure (16:66).

6. Flat-Earth Cosmology and Ritual Consequences

The Earth is described with terms for a flat expanse, carpet, bed, or level plain (88:20, 71:19, 2:22, 78:6–7, 20:53). Tafsir al-Jalalayn on 88:20 states that most legal scholars of its time held the Earth to be flat. Lane’s Lexicon entries (sataha, bisaatan, firashan, mahdan, etc.) confirm the semantic range. Ramadan fasting and the five daily prayers become impractical at high latitudes (2:187, 17:78). Facing Mecca on a sphere produces geometric contradictions between great-circle and rhumb-line paths (2:149).

7. Geology and Meteorology

A permanent barrier separates fresh and salt “seas” (25:53, 55:19–22). Mountains function as “pegs” that prevent the Earth from shifting (16:15, 78:6–7) and were “cast” onto the Earth (16:15). Chests contract with altitude as a theological sign (6:125). Earthquakes are framed as divine punishment (16:45, 29:37). Evaporation is omitted from the water-cycle description (43:11). “Mountains of hail” exist in the sky (24:43); classical tafsirs treat the language literally. Thunder and lightning are produced by an angel with a whip of fire (13:13); Jami` at-Tirmidhi 5:44:3117.

8. Zoology

An ant converses intelligibly and is understood by Solomon (27:18–19). Only four kinds of grazing livestock are enumerated (39:6, 6:142–144). Horses, mules, and donkeys are created ready-made for transport (16:8). All animals live in “communities” (6:38). Bird flight is attributed solely to divine power (16:79, 67:19).

9. History

A wall traps Gog and Magog until Judgment Day (18:96–101). Mary is placed in a Trinity-like configuration (5:116). Mary is conflated with Miriam, sister of Aaron and daughter of Imran (19:27–28, 66:12, 3:33–36); Sahih Muslim 2135 records the difficulty. Jews are said to regard Ezra (“Uzayr”) as the literal son of God (9:30). David invents coat-of-mail armor (34:10–11); archaeological and textual evidence places such armor later (Gabriel, The Ancient World, 2007; Robinson, Oriental Armour, 1995). Crucifixion appears in the eras of Joseph and Moses (12:41, 20:71), centuries before its historical use. “Pharaoh” functions as a proper name rather than a title (28:8–9). Nabatean tombs at al-Hijr are described as pre-Pharaonic homes (7:73–74, 15:80–83); Sahih Bukhari 3379 and UNESCO documentation date them to the Nabatean period. A “Samaritan” (al-Samiri) is present in the time of Moses (20:85, 20:95), anachronistic by centuries. A global flood under Noah drowns the world (11:40, 71:26); Tafsir Ibn Kathir and al-Jalalayn treat it as universal. Countable “dirham” coinage appears in ancient Egypt (12:20).

10. Linguistics and Sociology

Adam is taught “all the names” and speaks in complete sentences immediately (2:31, 55:3–4). Arabic revelation is presented as guaranteeing understanding (43:3). The people of Lot are the “first” to commit homosexual acts (7:80–81). A woman’s legal testimony is valued at half a man’s (2:282); Sahih Bukhari 304 explicitly links the rule to a “deficiency” in women’s intelligence.

11. Miracles, Magic, and the Supernatural

Sabbath-breakers are turned into apes (2:65). A golden-calf statue moos (20:88). A heavenly table is sent down for Jesus (5:114–115). Moses’s staff becomes a serpent (7:107). Jinn exist, possess humans, and build structures (18:50, 34:12–13, 72:1). Solomon commands an army of jinn, men, and talking birds (27:16–23). Magic, knot-spells, and the evil eye are real; angels teach sorcery (2:102, 113:1–5). Jonah survives inside a large fish (37:142). The Buraq carries Muhammad on the Night Journey (17:1). Body parts testify on Judgment Day (24:24). The sea splits for Moses (2:50). Solomon controls the wind (38:36). A murdered man is briefly resurrected by a piece of a sacrificed heifer (2:73). Hills and birds sing psalms with David (34:10).

12. Mathematical and Legal Consistency

Inheritance fractions in 4:11–12 and 4:176 can sum to more than 100 percent (example: wife 1/8 + daughters 2/3 + father 1/6 + mother 1/6 = 27/24). The post-Quranic doctrine of ‘awl (proportional reduction) was introduced to resolve the excess; the problem is internal to the text as revealed.

These points rest on the wording of the Quran, the earliest exegetical and hadith literature, classical Arabic lexicography, and independent scientific and historical evidence.
