Are "scientific miracles" in the Quran real?

How scholars have understood it

The verses. "Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing?" (21:30), Meccan. "And the heaven We constructed with strength, and indeed, We are [its] expander" (51:47), Meccan.

The modern claim. That 21:30 describes the Big Bang (a single original state, separated) and 51:47 the expanding universe.

Classical tafsir. Ibn Kathir reports Ibn ʿAbbas on 21:30: "the heavens were joined together and it did not rain, and the earth was joined together and nothing grew", until "rain came forth from the heavens and vegetation came forth from the earth"; al-Hasan and Qatada: "They were joined together, then they were separated by this air"; and his own gloss: "in the beginning they were all one piece… piled up on top of one another", then separated. On 51:47 he explains "We constructed… with strength" with Ibn ʿAbbas, Mujahid, Qatada and al-Thawri, and la-mūsiʿūn ("expander") as: "We made it vast and We brought its roof higher without pillars to support it."

Assessment. The words ratq (joined) and fatq (separated) and mūsiʿūn (making wide, or having the power to make wide) can be read as compatible with modern cosmology, and that compatibility can be a prompt for reflection. But Ibn Kathir, and the early authorities he reports, do not read these verses as describing an expanding universe or an initial singularity; the modern readings arose after the science. That is the pattern critics point to. So the honest statement is: these verses can be read in harmony with modern cosmology; they do not predict it.

The claim. That 23:12–14 — "a sperm-drop in a firm lodging… a clinging clot… a lump [of flesh]… bones… covered the bones with flesh" — matches modern embryology so exactly that it must be from God. Its best-known supporter was the Canadian anatomist Keith Moore, who is quoted as saying he had worked "for the past three years" with an embryology committee at King Abdulaziz University in Jeddah. With Abdul-Majeed al-Zindani, named there as Director of the Project of Scientific Miracles at that university, he produced a special edition of his textbook, The Developing Human, "with Islamic Additions" (Saunders, 1982; Dar Al-Qiblah, 1983). He is quoted as saying the Quranic descriptions "cannot be based on scientific knowledge in the seventh century" (Islamic Awareness, a site that promotes the claims).

Assessment. The stages named in 23:14 are the same words the site's sign page on the embryo (S4) examines, with their meanings and the classical readings. The current S4 page says the historian of science Joseph Needham noted parallels with Galen's Greek medicine; that has not yet been checked in Needham's text. The fair position is the site's general one: describe accurately, note what harmonises, and flag overclaims.

The speed of light. A popular claim derives the speed of light from 32:5 and the Moon's orbit. No source assessing it was read, so this page makes no judgement on it.

Al-Shatibi and the Arabs' usage. Muhammad Salim Abu ʿAsi, in his study of the Andalusian jurist al-Shatibi's al-Muwāfaqāt, writes in his own words that "the whole Quran was revealed in the established usage of the Arabs, without doubt" (translated). He says this in a section on why tafsir is still needed: Arabic words carry literal, figurative and implied meanings. The passage read says nothing about reading later sciences into the Quran.

Classical iʿjāz. According to Divlekci (2019), al-Baqillani names three aspects of the Quran's inimitability: its reports of the unseen ("gâipten haberler"), the Prophet's (pbuh) being ummī, and the uniqueness of its composition (naẓm).
