Qur’an 64:4 culminates in the phrase “wa-Allāhu ʿalīmun bidhāti al-ṣudūr” — “and Allah is the All-Knower of what is in the breasts” — the single most concentrated Qur’anic assertion that the human inner self is completely transparent to God, and the precise capacity that modern philosophy of mind shows is impossible for any human or scientific instrument to possess. That contrast is the spine of this commentary.

The verse and its center of gravity: Q 64:4 moves from God’s knowledge of the cosmos, to what people conceal (tusirrūn) and reveal (tuʿlinūn), to the climactic ʿalīmun bidhāti al-ṣudūr — knowledge of “the secret thoughts… more hidden than the secret” (al-Ṭabarī). All five classical mufassirūn read this as both a foundation for divine justice and a “threat” (waʿīd) to hypocrites who hide unbelief behind outward faith.

• The science–faith hook: Three landmark arguments — Chalmers’s “hard problem” (1995), Nagel’s “What Is It Like to Be a Bat?” (1974), and Jackson’s “Mary’s Room” (1982) — together with the fact that consciousness science has produced not one accepted account but a proliferating field (Robert Lawrence Kuhn’s 2024 taxonomy of roughly 225 theories) establish that another person’s first-person experience is in principle inaccessible to other humans and to instruments. The Qur’an asserts that God has exactly the access that humans and science provably lack.
• Shah’s contemporary overlay: Dr. Zia H. Shah argues that absolute, granular omniscience — including knowledge of “the most private human thoughts” — logically necessitates extra dimensions (Kaluza–Klein, string/M-theory, the holographic principle) as God’s “access mechanism,” paired with al-Ghazālī’s occasionalism and his “Four Books of God” framework. This is a 21st-century interpretive layer that must be transparently distinguished from the plain, moral-eschatological meaning of classical Sunni tafsir.

Abstract

Qur’an 64:4 affirms, in three ascending movements, divine knowledge of the heavens and earth, of what humans conceal and disclose, and finally of “what is in the breasts” (dhāt al-ṣudūr). This commentary integrates the Arabic text and transliteration, six named English translations, the readings of five classical mufassirūn (al-Ṭabarī, Ibn Kathīr, al-Qurṭubī, al-Rāzī, al-Zamakhsharī), a network of parallel verses on God’s knowledge of the inner self, and contemporary science and philosophy of mind. Its central thesis is that the privacy of the mental — the established result that no human and no scientific instrument can access another’s first-person subjective experience — renders the Qur’an’s claim that God knows dhāt al-ṣudūr a uniquely and irreducibly divine epistemic capacity. The essay then presents Dr. Zia H. Shah’s extra-dimensional and occasionalist framework as a contemporary theological response.

Key Findings

1. The verse’s structure is a deliberate ascent toward the interior. It proceeds outward-cosmic → behavioral (concealed/revealed acts) → innermost (the contents of the breasts). al-Zamakhsharī notes the threefold mention of knowledge is a “repetition of the threat” (takrīr al-waʿīd).
2. Classical consensus reads the verse morally and eschatologically, as a warning against hypocrisy and a guarantee that perfect justice requires a Judge who knows intentions — not as a statement about physics or neuroscience.
3. The phrase ʿalīmun bidhāti al-ṣudūr is a Qur’anic refrain (it occurs in this exact form at Q 3:154 and 64:4, with close variants at 8:43, 11:5, 31:23, 35:38, 39:7, 42:24, 57:6, 67:13), embedding 64:4 in a dense scriptural theme of divine knowledge of the heart.
4. Modern philosophy of mind independently establishes the “privacy of the mental” — the first-person/third-person gap that makes another’s inner experience inaccessible to observation or instrumentation. This is the strongest available bridge between the verse and contemporary thought.
5. Consciousness science has not converged; it has multiplied competing theories, which the essay can use to underscore the mystery of the very interiority the verse claims God knows completely.
6. Shah’s extra-dimensional thesis is a coherent, clearly-labeled contemporary overlay, not classical exegesis, and should be presented as such alongside the caveat that its physics (Orch-OR, the theological use of quantum mechanics) is contested.

1. Arabic Text, Transliteration, and Six Translations

Arabic (Q 64:4):

يَعۡلَمُ مَا فِي ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِ وَيَعۡلَمُ مَا تُسِرُّونَ وَمَا تُعۡلِنُونَۚ وَٱللَّهُ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ

Transliteration: Yaʿlamu mā fī al-samāwāti wa-al-arḍi wa-yaʿlamu mā tusirrūna wa-mā tuʿlinūn; wa-Allāhu ʿalīmun bidhāti al-ṣudūr.

Six named English translations:

1. Sahih International: “He knows what is within the heavens and earth and knows what you conceal and what you declare. And Allah is Knowing of that within the breasts.”
2. Abdullah Yusuf Ali: “He knows what is in the heavens and on earth; and He knows what ye conceal and what ye reveal: yea, Allah knows well the (secrets) of (all) hearts.” My Islam
3. Marmaduke Pickthall: “He knoweth all that is in the heavens and the earth, and He knoweth what ye conceal and what ye publish. And Allah is Aware of what is in the breasts (of men).” My Islam
4. Muhammad Asad: “He knows all that is in the heavens and on earth; and He knows all that you keep secret as well as all that you bring into the open: for God has full knowledge of what is in the hearts [of men].” alim
5. Sayyid Abul Aʿla Maududi: “He knows what is in the heavens and the earth, and knows what you conceal and what you disclose. Allah even knows what lies hidden in the breasts of people.” My Islam
6. Maulana Muhammad Ali (Lahore Ahmadiyya, 2010 edition): “He knows what is in the heavens and the earth, and He knows what you hide and what you manifest. And Allah is Knower of what is in the hearts.” alahmadiyya

Note the translators’ lexical choices for dhāt al-ṣudūr: “that within the breasts” (Sahih), “the (secrets) of (all) hearts” (Yusuf Ali), “what is in the breasts (of men)” (Pickthall), “what is in the hearts” (Asad, Muhammad Ali), “what lies hidden in the breasts of people” (Maududi). Dr. Ghali’s rendering is the most expansive — “the inmost (thoughts within) the breasts” — capturing the sense the classical commentators emphasize. My Islam

Context: The verse sits within Sūrat al-Taghābun (chapter 64, Medinan, two sections, 18 verses), one of the Musabbiḥāt (surahs opening with God’s glorification). Verses 1–4 form a unit: glorification of God (v.1), the creation of believers and disbelievers (v.2), creation “with truth” in “the best of forms” (v.3), and omniscience (v.4). The surah takes its name, al-Taghābun (“Mutual Loss and Gain” / “The Manifestation of Losses”), from verse 9, a name for the Day of Resurrection. Wikipedia + 2

2. Classical Tafsir — Five Mufassirūn on Q 64:4

al-Ṭabarī (Jāmiʿ al-bayān ʿan taʾwīl āy al-Qurʾān): “What you conceal” (tusirrūn) means secret speech and deeds among yourselves; “what you reveal” (tuʿlinūn) is what you make manifest. On the climax, he writes that God “is possessor of knowledge of the secret thoughts in the breasts of His servants, and of what their souls fold up within, which is more hidden than the secret (akhfā min al-sirr); nothing of that escapes Him.” He then draws an explicit moral warning: “Beware of concealing other than what you reveal, or harboring within yourselves other than what you display, for your Lord — nothing of that is hidden from Him; He counts it all up and is the Keeper over all of you.” Quran

Ibn Kathīr (Tafsīr al-Qurʾān al-ʿAẓīm): Treats verses 1–4 as a unit. After establishing God’s dominion (“His is the dominion”) and power (“whatever He wills occurs without resistance”), Ibn Kathīr writes that “Allah then informs of His knowledge of all that there is in the heavens, in the earth and in the souls.” He frames the verse as affirming that God witnesses His servants’ deeds and “will completely recompense them.” myislam + 3

al-Qurṭubī (al-Jāmiʿ li-aḥkām al-Qurʾān): A terse cross-reference to the recurring theme: “This has already been treated in more than one place. He is the Knower of the unseen and the seen (ʿālim al-ghayb wa-al-shahāda); nothing of what is in your breasts is hidden from Him” (فهو عالم الغيب والشهادة لا يخفى عليه شيء مما في صدوركم). Surah Quran + 2

Fakhr al-Dīn al-Rāzī (Mafātīḥ al-ghayb / al-Tafsīr al-kabīr): Reads 64:4 in deliberate connection with the preceding Sūrat al-Munāfiqūn (which concerned hypocrisy “in secret and in the open”), calling this verse “the most far-reaching threat (al-tahdīd al-bāligh)” against the hypocrites: God’s knowledge of “what you conceal” exposes the secret unbelief they hide while displaying belief outwardly. As an Ashʿarī theologian, al-Rāzī characteristically deploys the verse to affirm the comprehensiveness and perfection of divine knowledge (kamāl al-ʿilm). (Note: al-Rāzī’s confirmed framing of the verse is his connection to al-Munāfiqūn and the tahdīd; an exact word-for-word gloss of the specific clause is best verified against a printed edition of Mafātīḥ al-ghayb, vol. 30.) IslamWeb

al-Zamakhsharī (al-Kashshāf, Muʿtazilite): “He called attention, by His knowledge of what is in the heavens and the earth, then by His knowledge of what the servants conceal and reveal, then by His knowledge of the contents of the breasts (dhawāt al-ṣudūr), [to the fact] that nothing of the universals or the particulars (al-kulliyyāt wa-l-juzʾiyyāt) is hidden from Him or escapes Him — so it is His due that He be feared and guarded against.” He adds the rhetorical observation that “the repetition of [the mention of] knowledge carries the meaning of a repetition of the threat (takrīr al-waʿīd).” Consistent with Muʿtazilite doctrine (divine justice, human-authored acts), al-Zamakhsharī insists that unbelief is “the greatest ingratitude of servants toward their Lord” and is not part of God’s creation — “How ignorant is the one who blends unbelief into [God’s] creating.” greattafsirsgreattafsirs

Supplementary classical voices: Tafsīr al-Jalālayn glosses dhāt al-ṣudūr as “the secrets and convictions they contain” (al-asrār wa-al-muʿtaqadāt). Ibn ʿĀshūr (al-Taḥrīr wa-al-tanwīr) offers the most analytically rich reading: the verse refutes those who denied resurrection on the grounds that scattered bodies cannot be reassembled — the One who knows the secret in the soul, “finer and more hidden than the scattered atoms of bodies,” surely knows the location of every scattered particle; he parses dhāt al-ṣudūr as “the intentions and passing thoughts” (al-nawāyā wa-al-khawāṭir) held in the breast, and reads the closing clause as a tadhyīl (concluding amplification).

3. The Network of Parallel Verses on the Inner Self

• Q 50:16: “And We have already created man and know what his soul whispers to him, and We are closer to him than [his] jugular vein” (Sahih International). Ibn Kathīr stresses God’s “complete knowledge of all thoughts that cross the mind of man, be they good or evil”; the Maʿārif al-Qurʾān notes that by scholarly consensus the “closeness” is “nearness in terms of all-encompassing knowledge,” not physical proximity. Quranic Arabic Corpus + 2
• Q 40:19: “He knows that which deceives the eyes and what the breasts conceal” (Sahih International). Ibn Kathīr (via Ibn ʿAbbās and al-Ḍaḥḥāk) glosses “treachery of the eyes” as the furtive wink or false claim of sight, and “what the breasts conceal” (per al-Suddī) as “insinuating whispers.” Quranic Arabic Corpus + 2
• Q 3:29: “Say: Whether you conceal what is in your hearts or bring it into the open, God knows it: for He knows all that is in the heavens and all that is on earth” (Asad). IslamiCity
• Q 11:5: “He knows all that they keep secret as well as all that they bring into the open — for He has full knowledge of what is in the hearts [of men]” (Asad). IslamiCity
• Q 67:13: “And conceal your speech or publicize it; indeed, He is Knowing of that within the breasts.”
• Q 2:284: “Whether you show what is within yourselves or conceal it, Allah will bring you to account for it.”
• Q 13:10: “It is the same [to Him] concerning you whether one conceals [his] speech or one publicizes it.”

These verses establish that 64:4 is not an isolated claim but the recurring Qur’anic insistence that the interior life — intention, whisper, secret — lies entirely within divine knowledge.

4. The Hard Problem of Consciousness and the Privacy of the Mental

Chalmers (1995). David J. Chalmers, “Facing Up to the Problem of Consciousness,” Journal of Consciousness Studies 2(3):200–219, distinguishes the “easy problems” of consciousness (functionally definable capacities — information integration, discrimination, attention, reportability) from the “hard problem”: explaining why physical processing “is accompanied by experience.” His opening is now canonical: “Consciousness poses the most baffling problems in the science of the mind. There is nothing that we know more intimately than conscious experience, but there is nothing that is harder to explain.” The terms “hard problem” and “easy problems” were coined by Chalmers in a 1994 talk at the “Toward a Scientific Basis of Consciousness” conference in Tucson, Arizona; he later remarked to John Horgan, “I had no idea this whole ‘hard problem’ thing would blow up the way it did.” Ingenta Connect + 4

Nagel (1974). Thomas Nagel, “What Is It Like to Be a Bat?”, The Philosophical Review 83(4):435–450, grounds the subjectivity of experience: “an organism has conscious mental states if and only if there is something that it is like to be that organism — something it is like for the organism.” This “subjective character of experience… is not captured by any of the familiar, recently devised reductive analyses of the mental.” Even complete objective knowledge of a bat’s echolocation would not yield what it is like to be the bat — the foundational statement of the first-person/third-person gap. Uconn + 4

Jackson (1982/1986) — Mary’s Room. Frank Jackson’s “Knowledge Argument,” from “Epiphenomenal Qualia” (1982) and “What Mary Didn’t Know” (1986): Mary, a brilliant neuroscientist, learns every physical fact about color vision while confined to a black-and-white room. When she first sees red, “it seems just obvious that she will learn something… But then it is inescapable that her previous knowledge was incomplete… Ergo there is more to have than that, and Physicalism is false.” Subjective qualia, Jackson argues, are “left out of the physicalist story.” Wikipedia + 2

The proliferation of theories. Far from converging, consciousness science has multiplied accounts. Robert Lawrence Kuhn’s “A Landscape of Consciousness: Toward a Taxonomy of Explanations and Implications,” Progress in Biophysics and Molecular Biology, vol. 190 (August 2024), pp. 28–169 (DOI: 10.1016/j.pbiomolbio.2023.12.003), is a roughly 175,000-word survey; collaborator Àlex Gómez-Marín describes it as “a taxonomy of about 225 theories of consciousness,” organized into ten categories running “from the most physicalist: ‘consciousness is entirely a product of the brain,’ to the least: ‘consciousness is fundamental, primary, or even the sole reality.’” Kuhn’s stated aim is “to collect and categorize, not assess and adjudicate,” and he notes, “I have discussed consciousness with over 200 scientists and philosophers.” (In a 2025 New Scientist feature, “What 350 different theories of consciousness reveal about reality,” Kuhn extended the count to more than 350.) For scale: Anil Seth and Tim Bayne’s “Theories of consciousness,” Nature Reviews Neuroscience 23(7):439–452 (2022), reviewed just four prominent families (higher-order, global workspace, re-entry/predictive processing, integrated information) and observed that “in the case of consciousness, it is unclear how current theories relate to each other, or whether they can be empirically distinguished” — theories “seem to be proliferating” rather than being ruled out. Seth later summarized the contrast: his 2022 review listed 22 brain-based theories, while in 2024 Kuhn “counted more than 200.” ScienceDirect + 11

The privacy of the mental — the science-faith pivot. The decisive point for the commentary is not which theory is correct but a structural feature all of them confront: the inaccessibility of another’s inner experience. As Danko Georgiev puts it (“Inner privacy of conscious experiences and quantum information,” BioSystems, 2019): “The human mind is constituted by inner, subjective, private, first-person conscious experiences that cannot be measured with physical devices or observed from an external, objective, public, third-person perspective. The qualitative, phenomenal nature of conscious experiences also cannot be communicated to others in the form of a message composed of classical bits of information.” Consequently “there is no objective scientific way to determine if any other person, animal or object is conscious.” Thomas Metzinger calls this the “epistemic asymmetry” — we know experiences “through direct inner acquaintance and through access from the outside, i.e., the third person perspective”; Joseph Levine (1983) named it the “explanatory gap.” This is the verse’s hook: no human and no scientific enterprise can reach another’s innermost subjective experience — yet Q 64:4 asserts that God is ʿalīmun bidhāti al-ṣudūr, the Knower of precisely what is otherwise sealed.

5. Quantum Reality as a Posited Avenue of Divine Knowledge

The Penrose–Hameroff Orchestrated Objective Reduction (Orch-OR) model (“Quantum computation in brain microtubules? The Penrose–Hameroff ‘Orch OR’ model of consciousness,” Philosophical Transactions of the Royal Society A 356:1869–1896, 1998) proposes that quantum superposition and computation occur in neuronal microtubules, with collapse governed by Penrose’s “objective reduction” — a quantum-gravity threshold “ingrained in fundamental spacetime,” yielding outcomes “neither totally deterministic nor random.” Penrose advanced OR as a joint solution to the quantum measurement problem and the hard problem of experience. Caveat: Orch-OR is strongly contested. Per the standard critical literature, electronic motion in tubulin dimers occurs on the 10 fs–30 ps timescale, whereas Orch-OR requires coherence on a ~25 ms timescale; Reimers, McKemmish, McKenzie, Mark, and Hush (2009/2014) and others note the absence of empirical evidence for the required coherence (Max Tegmark earlier estimated decoherence at ~10⁻¹³ s). It is not accepted by mainstream neuroscience. Royal Society Publishing + 7

Quantum-information approaches to mind (Georgiev) draw an analogy between the incommunicability and inaccessibility of qualia and the no-cloning/inaccessibility properties of quantum information — a suggestive parallel rather than an established identity. In theological discussion, the observer effect and wavefunction collapse, entanglement/nonlocality, and superposition (as knowledge of counterfactuals) have all been invoked in models of divine action and omniscience. These are best presented as analogies and conjectures, not as physics that has been shown to underwrite theology.

6. Extra Dimensions in Modern Physics

• Kaluza–Klein (1919/1926): Theodor Kaluza proposed unifying gravity and electromagnetism by extending general relativity to a fifth dimension; Oskar Klein added the “cylinder condition,” compactifying the extra dimension into a circle “so tiny it cannot be detected.” thequran
• String/M-theory: Superstring theory requires ten total dimensions; M-theory requires eleven (ten of space, one of time), modeling our universe as a “brane” within a higher-dimensional “Bulk.”
• Holographic principle / AdS-CFT: The information of a three-dimensional volume can be encoded on its two-dimensional boundary; a higher-dimensional gravitational “Bulk” is dual to a lower-dimensional field theory on the boundary.
• The theological argument: A Being operating in, or transcending, extra dimensions could in principle access all states — including inner mental states — that are inaccessible from within 3+1 spacetime, “much like a three-dimensional observer can see the entirety of a two-dimensional plane without being visible to the two-dimensional inhabitants.” thequran

7. Dr. Zia H. Shah’s Extra-Dimensions Work (Dedicated Section)

Author profile. Dr. Zia H. Shah, MD, is a physician practicing in Upstate New York and Chief Editor of The Muslim Times (now reporting more than 43,000 social-media followers); he is board-certified in Internal Medicine, Pulmonary Disease, and Sleep Medicine, serves as Chair of Religion and Science for The Muslim Sunrise (“the oldest Muslim publication in North America”), directs the Internal Medicine Residency at Guthrie Lourdes Hospital, NY, and is the principal author of TheQuran.love (“The Glorious Quran and Science”), where he has published more than 400 articles. Themuslimtimes + 4

The flagship essay. “The Architecture of Omniscience: Extra-Dimensional Physics and the Islamic Metaphysics of Reality” (January 27, 2026) states the thesis directly in its abstract: “The Quranic identification of God as the ‘Knower of the Unseen and the seen’ (Alim al-Ghayb wa ash-Shahadah) implies a depth of knowledge that extends to every subatomic interaction, quantum state, and potentiality across the multiverse. This report argues that such absolute, granular omniscience logically necessitates the existence of extra spatial or temporal dimensions.” Shah’s signature move is a “reverse paradigm”: “if we are absolutely sure of the Quranic attributes of Allah, then we must conclude that the physical architecture of the universe includes extra dimensions to facilitate this all-encompassing access.” Crucially for Q 64:4, he lists among the objects of divine knowledge “the ‘intentions of the heart’ and the most private human thoughts, which are ‘witnessed’ even if they never manifest in the physical world,” along with “all counterfactuals.” He maps M-theory’s eleven-dimensional “Bulk” onto the Qur’anic “Seven Heavens” and the holographic principle onto the “Clear Record” (Kitāb Mubīn / Lawḥ Maḥfūẓ), and reframes quantum nonlocality theologically: “what seems like ‘magic’ or ‘spooky action’ to us is simply the result of a higher-dimensional connection that God uses to maintain the unity and coordination of the cosmos.” The essay is explicitly tagged consciousness, philosophy, physics. thequran + 4
