The secular hypothesis is easy to state: Muḥammad produced the Quran himself, perhaps sincerely, perhaps through religious genius, perhaps through adaptation of earlier traditions. The problem with the hypothesis is that once the Quran is placed in full view, the hypothesis explains less than its simplicity suggests, rather than that it is impossible to imagine.
The literary event itself
The Quran does not sound like ordinary Arabic prose and does not fit the established mould of poetry. It arrives in a distinct register, with recurrence, compression, rhetorical force, and thematic integration that struck its first hearers as extraordinary. A human genius can produce extraordinary speech. The question is whether the specific shape of the Quran (delivered responsively over more than two decades under radically changing conditions) is best explained that way.
The difficulty of the borrowing theory
The borrowing hypothesis also struggles. The Quran does not merely repeat biblical and late antique material. It reorders it, judges it, corrects it, and places it inside a rigorously unified theology centred on one sovereign God. Its treatment of prophets, revelation, law, eschatology, and moral accountability is a sustained world-picture, rather than a patchwork of hearsay. Borrowing can explain fragments. It explains a coherent totality far less well.
The Prophet’s role
Muḥammad’s personal history matters here. He was not known as a poet, schoolman, or trained theologian. He did not produce one literary mode before revelation and another after it through a gradual artistic apprenticeship. The Quran enters his life as a commanding voice that often rebukes him, redirects him, and speaks with an authority over him rather than from him. That internal asymmetry is difficult to fake across twenty-three years.
The Prophet’s own description of the experience
The hadith literature preserves the Prophet’s ﷺ own account of the experience of receiving revelation, which bears directly on the question of whether the Quran is something he could have produced from himself:
The hadith is the Prophet’s own self-report on the phenomenology of revelation, preserved with extraordinary care in the canonical collections. The features the Prophet describes are not the features of a man composing his own speech. The experience is described as something that comes to him, that imposes itself on him with physical difficulty, that leaves him with a content he then conveys. The hadith is consistent with the description of revelation across the Quran itself, where the speech is always identified as something the Prophet receives rather than something he generates. The Prophet’s own first-person account is, on the historical record, the testimony of a man describing not his own composition but his receipt of speech from a source other than himself. The borrowing-and-composition hypothesis has to explain why he would have constructed this elaborate self-report and maintained it consistently for twenty-three years, in addition to explaining the Quran itself.
The verses that argue against composition
The Quran itself contains material that is difficult to explain on the composition hypothesis. Several passages describe the Prophet’s own discomfort with what was being delivered through him. Several rebuke him for decisions he was inclined to make. The most striking is the case of Sūrat ʿAbasa (80:1–10), where the Prophet is rebuked for having frowned at a blind man who came seeking instruction while he was speaking with an influential Meccan leader. The rebuke is preserved in the canonical text. The narrative is preserved in the canonical biographical literature. A man composing his own work and claiming it was divine speech would be unlikely to preserve, in the supposedly authoritative text, a divine rebuke of his own social judgement.
The pattern is repeated. The Prophet is rebuked for making a personal exception to the rules in Sūrat al-Taḥrīm (66:1). He is rebuked for praying for forgiveness for his deceased uncle in Sūrat al-Tawbah (9:113–114). He is described as struggling with the weight of revelation, with the social opposition his message provoked, with the personal losses that accompanied his prophetic mission. None of this is what one would expect from a man producing self-aggrandising material. It is what one would expect from a man receiving and faithfully transmitting speech that did not originate with him.
Coherence through time
The Quran’s theological centre remains strikingly stable across migration, persecution, war, victory, grief, lawmaking, and communal growth. Its God is one, transcendent, near, judging, merciful, and sovereign throughout. Its moral architecture remains unified. Its rhetoric remains recognisably itself. That level of stability under pressure deserves explanatory weight.
The better inference
No single point compels belief on its own. Together they create a cumulative pressure. The literary challenge, the transmission history, the Prophet’s profile, the text’s sustained coherence, and the Quran’s commanding account of God all make the reduction to human authorship increasingly strained. The more the Quran is studied as a whole, the less “Muḥammad wrote it” feels like a serious explanation and the more it functions as a placeholder for mystery.
Read on its own terms, the matter becomes clearer. The Quran speaks with an authority that unifies truth, value, law, history, and worship in one voice. That integrated character is precisely what reductionist theories have failed to match. The stronger conclusion remains the classical one: the Quran came through Muḥammad, though it did not come from him.
The framework
The question of human authorship is ultimately a question about tawḥīd. If God is real and has spoken, then the Quran’s origin is divine. If God is not real, then of course the Quran is human. The entire case for God, built through cosmology, fine-tuning, consciousness, and morality, must be answered first. The honest inquirer does not start by assuming the conclusion. Īmān (genuine knowledge of truth) requires that the question of God’s existence be settled before the question of the Quran’s authorship can be meaningfully addressed.
The question ultimately returns to tawḥīd. If God is real, conscious, and communicative (as the arguments from cosmology, consciousness, and morality converge toward) then the existence of a revealed text is expected, rather than surprising. Īmān asks you to examine the text, its preservation, its coherence, and its challenge, and to recognise what the evidence points toward, rather than to accept the Quran’s divine origin on blind faith.
The question of whether Muḥammad authored the Quran is ultimately a question about tawḥīd: does this text come from God, or from a man? The Islamic answer rests on examination (the text’s internal coherence, its linguistic uniqueness, its preservation, and the character of the man who delivered it), rather than on assertion. Īmān is the recognition of truth after honest evaluation, rather than credulity.
