What is the Quran and why do Muslims believe it is from God?

In a Nutshell: The Quran (Arabic: القرآن, "the Recitation") is the central scripture of Islam, believed by Muslims to be the literal word of God (Allah) revealed to the Prophet Muhammad (pbuh) over a period of approximately twenty-three years (610 to 632 CE) through the Angel Jibril (Gabriel). Unlike the Bible, which Muslims and Christians alike understand as having been written by multiple human authors over centuries, the Quran is held by Muslims to be entirely divine in its origin: every word is from God, and Muhammad (pbuh) was its transmitter, not its author. Muslims believe the Quran is from God on the basis of several converging lines of evidence: its linguistic inimitability (no human has produced a text of comparable quality in Arabic despite an explicit Quranic challenge to do so), its historical preservation (the text has been transmitted in an unbroken chain from the Prophet's time to the present with a degree of accuracy unparalleled among ancient texts), its internal consistency (despite being revealed piecemeal over twenty-three years in response to diverse circumstances, it contains no contradictions), and its content (including knowledge that, Muslims argue, could not have been available to a seventh-century Arabian without divine assistance). This article examines the nature of the Quran, how it was revealed, how it has been preserved, and the arguments Muslims advance for its divine origin. Introduction The Quran is the most read book in the Arabic language and among the most influential texts in human history. It has shaped the law, literature, art, architecture, and daily life of civilisations stretching from Morocco to Indonesia for fourteen centuries. Approximately 1.9 billion people regard it as the direct word of God, and millions have committed its entire text to memory, a tradition of oral preservation that continues unbroken to this day. For Muslims, the Quran is not merely a book of guidance; it is the speech of God Himself, preserved in the exact form in which it was revealed. This claim is extraordinary, and it is treated as such within the Islamic tradition. The Quran itself invites scrutiny: "Will they not then reflect upon the Quran? If it had been from anyone other than Allah, they would have found within it much contradiction" (Quran 4:82). The Islamic case for the Quran's divine origin is not based on blind faith but on a set of arguments that have been developed, debated, and refined over fourteen centuries. For non-Muslims, the Quran can be a challenging text. Its structure is non-linear (it is not arranged chronologically or by narrative), its style alternates between legal injunctions, narrative passages, theological arguments, and poetic exhortations, and its Arabic is of a register that even native Arabic speakers find demanding. Understanding what the Quran is, how it came to exist, and why Muslims believe it is from God requires engagement with both the text itself and the rich tradition of scholarship that surrounds it. Key Terms Wahy (Arabic: وحي) means "revelation" and refers to the process by which God communicated the Quran to the Prophet Muhammad (pbuh) through the Angel Jibril. The Prophet described the experience of receiving revelation in various ways, including hearing a sound like the ringing of a bell and seeing the angel in human form. Surah (Arabic: سورة) means "chapter." The Quran contains 114 surahs, ranging in length from three verses (Surah al-Kawthar) to 286 verses (Surah al-Baqarah). Ayah (Arabic: آية) means "sign" or "verse." The Quran contains approximately 6,236 ayat (the plural of ayah). The word itself is significant: each verse is understood as a "sign" pointing to God. Mushaf (Arabic: مصحف) refers to the physical copy of the Quran in written form. The term is used to distinguish the written text from the Quran as recited speech, since the Quran's primary mode of existence in the Islamic tradition is oral. I'jaz (Arabic: إعجاز) means "inimitability" or "miraculous nature" and refers to the Quran's unique literary quality, which Muslims hold no human being can reproduce. The doctrine of i'jaz is the foundation of the primary Islamic argument for the Quran's divine origin. Hafiz (Arabic: حافظ) refers to a person who has memorised the entire Quran. The tradition of hifz (memorisation) has been continuous since the Prophet's time and is one of the mechanisms by which the Quran has been preserved. Tajweed (Arabic: تجويد) refers to the rules governing the correct pronunciation and recitation of the Quran. These rules ensure that the text is recited as it was recited by the Prophet (pbuh), preserving not only the words but the precise sounds. Qira'at (Arabic: قراءات) refers to the variant readings of the Quran, which are minor differences in pronunciation, vowelisation, and occasionally wording that have been transmitted through authenticated chains of narration from the Prophet (pbuh). The major qira'at (typically seven or ten are recognised) are all considered authentic and divinely sanctioned. Evidences Quranic Verses "Indeed, it is We who sent down the Quran, and indeed, We will be its guardian." (Quran 15:9) "This is the Book about which there is no doubt, a guidance for those who are mindful of God." (Quran 2:2) "Will they not then reflect upon the Quran? If it had been from anyone other than Allah, they would have found within it much contradiction." (Quran 4:82) "Say: If mankind and the jinn gathered together to produce the like of this Quran, they could not produce the like thereof, even if they helped one another." (Quran 17:88) "And if you are in doubt about what We have sent down upon Our servant, then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful." (Quran 2:23) "We have not neglected in the Book a thing." (Quran 6:38) "Indeed, this Quran guides to that which is most suitable and gives good tidings to the believers who do righteous deeds that they will have a great reward." (Quran 17:9) "The month of Ramadan in which the Quran was revealed, a guidance for the people and clear proofs of guidance and criterion." (Quran 2:185) Hadiths Aisha (ra) reported that al-Harith ibn Hisham asked the Prophet (pbuh): "O Messenger of Allah, how does the revelation come to you?" He replied: "Sometimes it comes to me like the ringing of a bell, and that is the hardest on me. Then it passes from me and I have understood what was said. And sometimes the angel comes to me in the form of a man and speaks to me, and I understand what he says." (Sahih al-Bukhari and Sahih Muslim) The Prophet (pbuh) said: "The best of you are those who learn the Quran and teach it." (Sahih al-Bukhari) The Prophet (pbuh) said: "This Quran was revealed in seven ahruf (modes). Recite whichever of them is easy for you." (Sahih al-Bukhari and Sahih Muslim) This hadith establishes the basis for the qira'at (variant readings) tradition. The Prophet (pbuh) would review the Quran with Jibril once every Ramadan, and twice in the final year of his life. (Sahih al-Bukhari) This practice ensured the accuracy of the text during the Prophet's lifetime. Companions' Opinions Zayd ibn Thabit (ra), the Prophet's primary scribe, played a central role in the compilation of the Quran into a single written mushaf during the caliphate of Abu Bakr (ra), and in the standardisation of the text during the caliphate of Uthman (ra). He described the responsibility as so weighty that he said: "By Allah, if they had asked me to move a mountain, it would not have been heavier upon me than what they asked me to do in compiling the Quran." (Sahih al-Bukhari) Uthman ibn Affan (ra), the third caliph, ordered the production of standardised copies of the Quran and their distribution to the major cities of the Muslim world, while ordering the destruction of variant personal copies to prevent divergence. This act of standardisation is one of the most significant events in the history of textual preservation. Abdullah ibn Mas'ud (ra) was one of the earliest and most accomplished reciters of the Quran among the companions. He reportedly said: "By Allah, there is no surah revealed in the Book of Allah but I know where it was revealed, and there is no verse but I know about whom it was revealed." Traditional Scholars' Quotes Al-Baqillani (10th to 11th century): In "I'jaz al-Quran" (The Inimitability of the Quran), al-Baqillani produced one of the earliest and most influential systematic arguments for the Quran's literary inimitability. He compared the Quran's style with the finest Arabic poetry and prose and argued that it occupied a unique literary category that no human work had matched. Al-Suyuti (15th century): In "al-Itqan fi Ulum al-Quran" (The Perfection in the Sciences of the Quran), al-Suyuti compiled the most comprehensive classical treatment of Quranic sciences, covering the history of revelation, compilation, variant readings, abrogation, and interpretation. Al-Zarkashi (14th century): In "al-Burhan fi Ulum al-Quran" (The Proof in the Sciences of the Quran), al-Zarkashi provided a systematic treatment of Quranic sciences that remains a foundational reference. Ibn Khaldun (14th century): In "al-Muqaddimah," Ibn Khaldun noted that the Arabs, despite being the most eloquent people in their language, were unable to meet the Quranic challenge to produce a comparable text, and that this failure itself constitutes evidence of the Quran's supernatural origin. Analysis: The Case for the Quran's Divine Origin The Islamic case for the Quran's divine origin rests on several converging lines of argument. Each is substantial on its own; their cumulative force, Muslims argue, is compelling. The Argument from Linguistic Inimitability (I'jaz). This is the oldest and most central argument. The Quran itself issues an explicit challenge: produce a single surah comparable to it (Quran 2:23). The challenge was issued to the Arabs of the seventh century, who were the most accomplished practitioners of the Arabic language and for whom poetry and oratory were the highest art forms. The failure of anyone to meet this challenge, despite the intense motivation of the Prophet's opponents to discredit him, is considered the primary miracle of the Quran. The argument is not merely that the Quran is beautiful Arabic (though it is) but that it occupies a unique literary category. Arabic literature traditionally recognised two categories: poetry (shi'r) and prose (nathr). The Quran fits neither. It has a rhythmic, cadenced quality that resembles poetry but does not follow any known poetic metre. It has the discursive quality of prose but with a phonetic and structural patterning that prose does not possess. Al-Baqillani, al-Jurjani, and other classical scholars analysed this quality in minute detail and concluded that the Quran constitutes a third category of Arabic expression (nazm) that has no human parallel. The force of this argument is greatest for those who can engage with the Quran in Arabic; in translation, much of the linguistic quality is inevitably lost. The Argument from Preservation. The Quran's textual preservation is historically remarkable. The text was memorised in its entirety by numerous companions during the Prophet's lifetime, was written down by scribes under the Prophet's direction, was compiled into a single written mushaf within two years of the Prophet's death (during the caliphate of Abu Bakr), and was standardised and distributed across the Muslim world within twenty years (during the caliphate of Uthman). The combination of mass oral memorisation (transmitted through unbroken chains to the present day) and written transmission has produced a text whose integrity is attested by both Muslim and non-Muslim scholars. The manuscript evidence, including early Quranic manuscripts such as the Sanaa palimpsest and the Birmingham manuscript (radiocarbon-dated to the Prophet's lifetime or shortly after), confirms the essential stability of the text. The Quran itself attributes this preservation to divine protection: "Indeed, it is We who sent down the Quran, and indeed, We will be its guardian" (Quran 15:9). Muslims see the historical fact of the Quran's preservation as the fulfilment of this divine promise. The Argument from Internal Consistency. The Quran was revealed piecemeal over twenty-three years in response to diverse circumstances: questions from companions, challenges from opponents, specific events, and general guidance. Despite this piecemeal revelation, the Quran invites scrutiny of its consistency: "If it had been from anyone other than Allah, they would have found within it much contradiction" (Quran 4:82). Scholars have argued that the absence of contradiction across a text revealed over more than two decades, addressing theology, law, ethics, narrative, and prophecy, is evidence of a single, omniscient authorial source. Critics have proposed various alleged contradictions, which Muslim scholars have addressed in detail in the tafsir literature; the debate is ongoing, but Muslims maintain that no genuine contradiction has been demonstrated. The Argument from Content. Muslims argue that the Quran contains knowledge that could not have been available to a seventh-century Arabian merchant without divine assistance. This argument takes several forms. The first concerns historical knowledge: the Quran corrects details of Biblical narratives (such as the title of the Egyptian ruler in the Joseph story, where the Quran uses "king" rather than "pharaoh," consistent with the historical fact that the Hyksos rulers of that period did not use the title "pharaoh"). The second concerns what are sometimes called "scientific indications": passages that describe natural phenomena (embryological development, the water cycle, the expansion of the universe) in terms that, Muslims argue, are consistent with modern scientific understanding and would not have been known in seventh-century Arabia. This argument requires caution; the "scientific miracles of the Quran" genre has been criticised by Muslim scholars including Nidhal Guessoum for over-reading modern science into pre-modern texts, and the strongest version of the argument focuses on a small number of clear cases rather than on extravagant claims. The third concerns prophecy: the Quran makes predictions (such as the Roman victory over the Persians in Surah al-Rum, 30:2 to 4) that were fulfilled, which Muslims cite as evidence of divine foreknowledge. The Argument from the Prophet's Character. This argument is supplementary but important. The Prophet Muhammad (pbuh) was known among the Quraysh as al-Amin (the Trustworthy) before his prophetic mission began. He was not a poet, and the Quran's opponents explicitly distinguished it from poetry (Quran 69:41). The Quran's content sometimes corrected or rebuked the Prophet himself (as in Surah Abasa, 80:1 to 10, where the Prophet is admonished for turning away from a blind man), which would be unlikely in a text authored by the Prophet for his own purposes. His life of simplicity, hardship, and personal sacrifice is inconsistent with the profile of a conscious fabricator. Muslims argue that the most parsimonious explanation of the evidence, the character of the Prophet, the nature of the text, and the circumstances of its production, is that the Quran is what it claims to be: a revelation from God. 5 Misconceptions about the Quran "The Quran was written by Muhammad." Islam holds that Muhammad (pbuh) was the recipient of the Quran, not its author. The Prophet was unlettered (ummi), and the Quran repeatedly distinguishes between the Prophet's own words (preserved in the hadith literature) and the divine revelation (the Quran). The two bodies of text differ dramatically in style, vocabulary, and register, which Muslims cite as evidence that they have different sources. "The Quran is a later copy of the Bible." While the Quran addresses many of the same figures and events as the Bible (Adam, Noah, Abraham, Moses, Jesus), it does so in substantially different ways, correcting what Islam considers errors in the Biblical accounts and providing additional material not found in the Bible. The Islamic position is that the Quran, the Torah, and the Injil all originate from the same divine source, but that the earlier scriptures have been altered over time while the Quran has been preserved. "The Quran promotes violence." Verses that address warfare (such as Quran 9:5 and 2:191) are invariably cited without their immediate context, which specifies the circumstances (defence against active aggression, violation of treaties) and the limits (prohibition of aggression against non-combatants, requirement to accept peace when offered). Classical tafsir treats these verses as addressing specific historical situations rather than as open-ended commands. A companion article on this site addressing jihad explores this topic in full. "The Quran has been altered over time." The manuscript evidence, the unbroken chain of oral memorisation (with millions of huffaz alive today who can recite the entire text from memory), and the testimony of both Muslim and non-Muslim scholars of textual history confirm the essential integrity of the Quranic text. The existence of variant readings (qira'at) is sometimes cited as evidence of alteration, but these variants were transmitted from the Prophet himself and represent divinely sanctioned modes of recitation, not scribal errors or later amendments. "You need to know Arabic to benefit from the Quran." While the full linguistic depth of the Quran is accessible only in Arabic, reliable translations exist in virtually every major language, and millions of non-Arabic-speaking Muslims engage deeply with the Quran through translation, tafsir, and study circles. The Quran's guidance is universal, and the tradition has always supported making its meaning accessible to all. 5 Objections Addressed Regarding the Quran's Divine Origin "The Quran's literary quality is a matter of subjective taste, not objective evidence." The i'jaz argument does not rest on subjective aesthetic preference but on the historical fact that the Quran's challenge has gone unmet. The Arabs of the seventh century had every motive and every capability to produce a rival text, and their failure to do so, acknowledged by the Prophet's most determined opponents, is treated as an objective datum rather than a matter of taste. Whether this datum constitutes proof of divine origin is a further question, but the literary uniqueness of the Quran within the Arabic tradition is acknowledged by Muslim and non-Muslim Arabists alike. "The preservation of the Quran is not miraculous; other ancient texts have been well preserved." The Quran's preservation is distinctive in its combination of mass oral memorisation (by thousands of individuals in every generation, through authenticated chains of transmission) and early written codification. No other ancient text of comparable length has been preserved through a dual oral-written system of this rigour. The Dead Sea Scrolls, for instance, demonstrate the preservation of portions of the Hebrew Bible, but the Quran's complete text was standardised within twenty years of its completion and has been continuously memorised in its entirety by millions of people in every subsequent generation. "The 'scientific miracles' argument is unconvincing because the verses are vague enough to be read retrospectively." This criticism has merit, and serious Muslim scholars (including Nidhal Guessoum) have cautioned against over-reliance on the "scientific miracles" argument. The strongest version of the argument does not claim that the Quran is a science textbook but notes a small number of passages whose content is difficult to explain as the product of seventh-century knowledge. The argument from content is one of several converging lines of evidence, not the sole or primary basis for the Quran's divine origin claim. "The variant readings (qira'at) prove that the Quran has not been perfectly preserved." The qira'at are not errors or later additions; they are authenticated modes of recitation transmitted from the Prophet (pbuh) through named chains of narrators. The Prophet himself stated that the Quran was revealed in seven ahruf (Sahih al-Bukhari and Sahih Muslim). The differences between the major qira'at are minor (matters of pronunciation, vowelisation, and occasionally the form of a word) and do not affect the meaning of any theological or legal principle. Their existence demonstrates the richness of the oral tradition rather than its unreliability. "Is it not circular to use the Quran to prove the Quran is from God?" The Islamic argument does not proceed in a circle. It begins with the observable properties of the text (its literary quality, its preservation, its consistency, its content) and argues that these properties are best explained by a divine source. The Quran's own claims about itself (such as the challenge to produce a comparable text) are part of the evidence to be evaluated, not assumptions that are taken for granted. The argument is an inference to the best explanation, not a circular proof. FAQs: What Is the Quran and Why Do Muslims Believe It Is from God? "How long does it take to memorise the entire Quran?" The time varies depending on the individual, but most students who pursue full-time hifz (memorisation) complete it in one to three years. Part-time memorisation may take longer. The Quran contains approximately 77,000 words, and the memorisation is typically done under the supervision of a qualified teacher who ensures accuracy of pronunciation and recitation according to the rules of tajweed. "Is the Quran arranged chronologically?" No. The Quran is arranged roughly from longest surah to shortest (with the exception of Surah al-Fatihah, the opening chapter), not in the order of revelation. The arrangement is understood by Muslims to be divinely ordained (the Prophet instructed the scribes on the placement of each verse and surah) rather than a later editorial decision. "What is the difference between the Quran and the hadith?" The Quran is the word of God revealed through the Angel Jibril, recited in prayer, and preserved in its exact Arabic wording. The hadith is the recorded speech, actions, and approvals of the Prophet Muhammad (pbuh), transmitted by his companions. The two are distinct in origin, authority, and literary character: the Quran's Arabic is considered inimitable, while the hadith is the Prophet's own speech in his own words. "Can women recite the Quran?" Yes. Women recite the Quran in prayer, in personal study, in memorisation programmes, and in educational settings. The scholarly debate about whether women may recite the Quran aloud in the presence of non-mahram men is a question of etiquette in specific contexts, not a prohibition on women engaging with the text. Aisha (ra), the Prophet's wife, was one of the foremost authorities on the Quran among the companions. "How should a non-Muslim approach reading the Quran?" With an open mind and, ideally, with a reliable translation that includes brief contextual notes. Widely recommended English translations include those by M.A.S. Abdel Haleem (Oxford University Press), Sahih International, and Muhammad Asad. Reading a short introduction to the Quran's structure and historical context before beginning can help orient the reader. The Quran is not arranged like a novel; approaching it as a collection of interconnected themes rather than a linear narrative will make the reading experience more productive. Conclusion The Quran is the foundation of Islam: its theology, its law, its ethics, its spirituality, and its daily practice all flow from this single text. Muslims believe it is the word of God on the basis of its linguistic inimitability, its historical preservation, its internal consistency, its content, and the character of the Prophet who delivered it. These arguments have been developed, tested, and refined across fourteen centuries of scholarship, and they remain the subject of serious engagement by both Muslim and non-Muslim academics. For the Muslim, the Quran is not merely a book to be studied but a living presence to be recited, memorised, and lived. For the non-Muslim, it is a text of immense historical, literary, and theological significance that rewards careful reading. And for anyone seeking to understand Islam, the Quran is the indispensable starting point: every other aspect of the tradition, from the hadith to the law to the mystical tradition, is ultimately derived from and measured against this single, remarkable text.
