The Qur’an occupies a unique place in the religious, intellectual, and legal history of humanity. For Muslims, it is not only the central religious scripture but also the literal and final word of God (Allah) revealed to the Prophet Muhammad (peace be upon him) through the Angel Jibrīl over a period of twenty-three years (610–632 CE). The Qur’an serves as a comprehensive source of guidance encompassing matters of faith, law, ethics, social order, and human conduct. Its eloquence, linguistic precision, thematic harmony, and transformative moral vision have positioned it as the foundational text of Islamic civilization.
1. The Qur’an as Divine Revelation
The Qur’an describes itself as tanzīl (a sent-down revelation) and kalām Allāh (the speech of Allah). It is not considered a product of human authorship, reflection, or philosophy; rather, it is believed to be verbatim divine communication. In Surah al-Najm, the Qur’an asserts:
“He does not speak from his own desire. It is only revelation sent down to him.”
(Qur’an 53:3–4)
This self-attestation establishes the Qur’an as a revealed text whose authority and authenticity derive from its divine origin.
2. Structure and Composition
The Qur’an consists of:
- 114 surahs (chapters),
- approximately 6,236 verses,
- arranged not chronologically, but according to divine instruction.
Its chapters vary greatly in length, from Surah al-Baqarah (286 verses) to Surah al-Kawthar (3 verses). The language of the Qur’an is classical Arabic (al-‘Arabiyyah al-fuṣḥā), characterized by unparalleled linguistic style, rhetorical depth, and rhythmic excellence. Muslim scholars regard this inimitable style as part of its divine nature (i‘jāz al-Qur’ān).
3. Authenticity and Preservation of the Qur’an
One of the most distinguishing features of the Qur’an is the belief—held unanimously by Muslims and supported by historical evidence—that the Qur’an has been preserved word-for-word since its revelation in the 7th century. This preservation is affirmed in the Qur’an itself:
“Indeed, We sent down the Reminder, and indeed, We will be its guardian.”
(Qur’an 15:9)
This verse is understood by exegetes such as Al-Ṭabarī, Ibn Kathīr, and Al-Qurṭubī as a divine promise guaranteeing textual preservation until the end of time.
3.1 Preservation During the Prophet’s Lifetime
The Qur’an was preserved through two simultaneous processes:
(a) Oral Preservation (Ḥifẓ)
Arab society was primarily oral, and memorization was a core cultural skill. The Prophet (peace be upon him) encouraged his companions to memorize the Qur’an, and a large group—known as ḥuffāẓ—committed the entire text to memory. The Qur’an states:
“Rather, it is clear verses in the hearts of those who have been given knowledge.”
(Qur’an 29:49)
(b) Written Preservation (Kitābah)
The Prophet dictated revelations to more than 40 appointed scribes, including Zayd ibn Thābit, Ubayy ibn Ka‘b, and Ali ibn Abi Talib. Verses were written on:
- parchment,
- leather,
- palm stalks,
- and bones.
The Prophet personally supervised this writing, ensured correct placement of verses, and reviewed the entire Qur’an with the Angel Jibrīl annually, and twice in his final year (Hadith: Bukhārī, Kitāb Faḍā’il al-Qur’ān).
3.2 Preservation After the Prophet’s Death
After the Prophet’s passing, the preservation of the Qur’an continued with meticulous care.
(a) Compilation under Abu Bakr (11 AH / 632 CE)
After the Battle of Yamāmah, where many memorizers were martyred, Caliph Abu Bakr, on Umar’s advice, ordered Zayd ibn Thābit to compile the Qur’an into a single manuscript. Zayd gathered the text using a dual-verification method:
- memorization by multiple companions, and
- written fragments authenticated in the Prophet’s presence.
This codex (al-Muṣḥaf al-Awwal) became the official reference copy.
(b) Standardization under Uthmān ibn Affān (24–30 AH / 644–656 CE)
As Islam spread beyond Arabia, minor dialectal variations emerged. Uthmān ordered the preparation of a standardized Qur’anic codex in the Qurayshi dialect. Again headed by Zayd ibn Thābit, this committee produced several identical copies dispatched to major Islamic regions, ensuring absolute textual uniformity. Uthmān’s recension (al-Muṣḥaf al-‘Uthmānī) remains the basis for all Qur’ans worldwide today.
Modern manuscripts—including the Topkapi, Samarkand, and Birmingham manuscripts—correspond closely to the Uthmānic codex, affirming its historical authenticity.
4. Continuous Outer and Inner Preservation
4.1 Outer Preservation: Manuscripts and Textual Continuity
Muslim scribes meticulously copied the Qur’an across centuries. No variant codex, alternative chapter order, or missing surah exists in Islamic history. This contrasts with many ancient scriptures whose textual history shows fragmentation or redaction.
4.2 Inner Preservation: Memorization Tradition
Memorization remains a living tradition. Millions worldwide know the Qur’an by heart today, making it the most memorized book in human history. This oral continuity acts as a safeguard against textual corruption.
5. Preservation of Language and Recitation (Qirā’āt)
The Qur’an is preserved not only in its words but also in its sound and pronunciation through the science of Qirā’āt (canonical recitations). These recitations represent phonetic modes taught by the Prophet himself and transmitted with mutawātir (mass-transmitted) chains. This multidimensional preservation—textual, oral, and phonetic—has no parallel in world scripture.
The Qur’an is thus understood in Islamic scholarship as a fully preserved, divinely protected revelation whose authenticity is supported by:
- its self-affirmation of protection,
- rigorous memorization,
- controlled written documentation,
- early authoritative compilation,
- and continuous global transmission.
Its preservation is not merely a matter of faith but is strengthened by manuscript evidence, historical documentation, and the uninterrupted chain of reciters across centuries. This unique preservation underpins the Qur’an’s role as the supreme source of Islamic law, theology, and guidance.
The Supreme Source of Islamic Law
The Qur’an occupies the highest and most authoritative position within the hierarchy of Islamic legal sources. Considered by Muslims to be the literal and unaltered word of God (Allah), revealed to the Prophet Muhammad (peace be upon him) over twenty-three years, it forms the epistemic and normative foundation of Islamic jurisprudence (fiqh) and legal theory (uṣūl al-fiqh). Its 114 chapters contain legal commands, ethical values, universal principles, and socio-moral guidance that together operate as the constitutional core of the Sharī‘ah. Islamic jurists from all schools unanimously agree that the Qur’an is the aṣl al-aṣl—the “root of all roots”—from which all other sources of law derive their authority.
1. The Qur’an as Divine Legislation
1.1 Revelation and Authority
The Qur’an presents itself as direct divine legislation. Allah states:
“Falsehood cannot approach it from before it nor from behind it; [it is] a revelation from the Wise, the Praiseworthy.”
(Qur’an 41:42)
The doctrine of preservation and authenticity is also affirmed:
“Indeed, We have sent down the Reminder, and We will surely guard it.”
(Qur’an 15:9)
These verses establish that the Qur’an, unlike secondary sources such as hadith or juristic opinion, is beyond critique and alteration. Al-Shāfi‘ī (d. 204 AH) in al-Risālah asserts that the Qur’an’s definitive textual authenticity (qaṭ‘iyyat al-thubūt) is the basis for its primacy over all other sources (Shāfi‘ī, al-Risālah, ed. Ahmad Shākir, Cairo, 1940, pp. 19–23).
2. Ayāt al-Aḥkām: Legal Verses in the Qur’an
Classical jurists identified approximately 500 verses dealing explicitly with legal commands (Ayāt al-Aḥkām) (al-Jaṣṣāṣ, Aḥkām al-Qur’ān, vol. 1, p. 5). These verses address a broad spectrum of legal fields:
2.1 Ritual Law (‘Ibādāt)
Prayer (2:43), fasting (2:183), zakāt (9:60), and pilgrimage (2:196).
2.2 Family Law
Marriage (4:3), divorce and waiting periods (2:228–235), inheritance (4:11–12), and custodial responsibilities.
2.3 Commercial Law
Contractual obligations (2:282, the longest verse in the Qur’an), prohibition of usury (2:275–279), and ethical business conduct.
2.4 Criminal Law
Punishments for theft (5:38), murder and qisas (2:178), zina (24:2), and qadhf (24:4).
2.5 Governance and Justice
Judicial standards (4:135), impartiality (5:8), and principles of public welfare and consultation (42:38).
Thus, the Qur’an provides both substantive rules and broader value frameworks that shape the entire legal system.
3. Qur’anic Statements on Its Role as Supreme Legal Authority
Numerous verses affirm the Qur’an as the ultimate legislative source.
3.1 Judgement Must Be Based on the Qur’an
“We have revealed to you the Book with the truth so that you may judge between people by what Allah has shown you.”
(Qur’an 4:105)
The verse directly commands the Prophet (peace be upon him) to adjudicate through Qur’anic revelation. Al-Ṭabarī explains that this establishes the Qur’an as the aṣl of all judicial rulings (Ṭabarī, Jāmi‘ al-Bayān, vol. 5, p. 114).
3.2 Comprehensive Guidance
“We have sent down to you the Book as clarification for all things and guidance and mercy and good tidings for the Muslims.”
(Qur’an 16:89)
Ibn Kathīr interprets “clarification for all things” as referring to all necessary matters of guidance, law, ethics, and governance (Ibn Kathīr, Tafsīr, vol. 4, p. 594).
3.3 Rejecting Judgement Outside Revelation
“Whoever does not judge by what Allah has revealed—those are the disbelievers.”
(Qur’an 5:44)
Classical jurists viewed this verse as establishing a theological imperative for legal adherence to revelation (al-Māwardī, al-Ḥāwī al-Kabīr, vol. 1, p. 21). Though interpretations differ on its specific legal implications, its role in affirming the Qur’an’s supremacy is undisputed.
4. Universal Principles and Adaptability of Qur’anic Law
The Qur’an is not a rigid code but an adaptable legal framework. Modern scholars such as Fazlur Rahman and Wael Hallaq emphasize that its principles are both situation-specific and universal.
4.1 Fixed Rules (Qaṭ‘iyyāt)
These include explicit, unchanging injunctions:
- inheritance shares (4:11–12),
- riba prohibition (2:275),
- zakāt categories (9:60).
4.2 Flexible General Principles
Examples include:
- justice (4:58),
- merciful governance (12:64),
- removal of hardship (2:185),
- public welfare (5:2),
- prohibition of harm (Hadith: Ibn Mājah, 2341).
These allow Islamic law to remain relevant across changing contexts.
5. The Methodology of Deriving Law from the Qur’an
Islamic legal theory requires systematic interpretation through uṣūl al-tafsīr and uṣūl al-fiqh.
5.1 Linguistic Analysis
Understanding grammar, rhetoric, and semantics is essential (al-Zarkashī, al-Burhān fī ‘Ulūm al-Qur’an, vol. 1, pp. 178–201).
Grammar, syntax, morphology, and rhetoric determine the legal force of the verse.
Words may indicate obligation (wujūb), recommendation (nadb), or permissibility (ibāḥah).
5.2 Asbāb al-Nuzūl (Occasions of Revelation)
Historical context clarifies the intent behind verses (al-Wāḥidī, Asbāb al-Nuzūl, pp. 5–7).
5.3 Tafsīr Through the Sunnah
The Prophet explained numerous Qur’anic injunctions through his words, actions, and approvals (Ṣaḥīḥ al-Bukhārī, Kitāb al-I‘tiṣām, Hadith 7288).
5.4 Interpretation by the Companions
The Companions’ exegesis—particularly Ibn ‘Abbās and Ibn Mas‘ūd—is foundational (al-Suyūṭī, al-Itqān, vol. 2, pp. 187–188).
5.5 Legal Theory (Uṣūl al-Fiqh)
When the Qur’an offers general wording, jurists apply:
- qiyās (analogy),
- maṣlaḥah mursalah (public interest),
- sadd al-dharā’i‘ (blocking harm),
- istihsān (juristic equity).
These tools extend Qur’anic guidance to new circumstances.
6. Relationship with Secondary Sources
While secondary sources hold legal authority, they remain subordinate to the Qur’an.
6.1 Sunnah
Clarifies and elaborates Qur’anic injunctions (Shāfi‘ī, al-Risālah, pp. 77–85).
6.2 Ijmā‘
Represents a collective agreement based on Qur’anic and Sunnah principles (al-Ghazālī, al-Mustaṣfā, vol. 1, p. 110).
6.3 Qiyās
Extends Qur’anic principles to unprecedented cases (Abu Ḥanīfah, cited in al-Kāsānī, Badā’i‘ al-Ṣanā’i‘, vol. 7, pp. 3–5).
No secondary source may contradict the Qur’anic text; this is a universal maxim across the four Sunni schools.
7. No Secondary Sources Can Overrule the Qur’an:
7.1 The Qur’an as the Supreme Source of Sharī‘ah
In Islamic jurisprudence, the Qur’an holds the status of al-masdar al-awwal (the first and supreme source of law). It is the direct, verbatim revelation of Allah and therefore possesses absolute and unquestionable authority. Unlike other sources of Islamic law, the Qur’an is:
- textually definitive (qaṭ‘ī al-thubūt),
- protected from alteration (Qur’an 15:9),
- and universally binding on all Muslims.
Because of this divine origin and preservation, Islamic legal theory establishes a unanimous principle that no other source can contradict, modify, or supersede any ruling explicitly stated in the Qur’an.
7.2 Hierarchy of Islamic Sources and Their Authority
Islamic law is built upon a structured hierarchy:
- The Qur’an – primary, supreme, and infallible
- The Sunnah – explanation and practical application of the Qur’an
- Ijma‘ (consensus) – collective agreement of qualified scholars
- Qiyās (analogy) – application of Qur’anic principles to new issues
- Other juristic tools – such as istiḥsān, maṣlaḥah, ‘urf, etc.
In this hierarchy, all secondary sources derive their authority from the Qur’an. They are tools to interpret, elaborate, or apply Qur’anic commands—not to oppose or replace them.
7.3 Why Secondary Sources Cannot Overrule the Qur’an
The Qur’an describes itself as the final criterion (al-furqān):
“Blessed is the One who sent down the Criterion upon His servant.”
(Qur’an 25:1)
A “criterion” means a final standard by which all judgments must be evaluated. Therefore, any opinion or interpretation contradicting the Qur’an automatically becomes invalid.
7.3 Divine Command Not to Judge Against Revelation
Multiple verses prohibit judging contrary to Allah’s revelation:
“Whoever does not judge by what Allah has revealed – they are the disbelievers.”
(Qur’an 5:44)
“It is not for a believer, man or woman, when Allah and His Messenger have decreed a matter, to have a choice in their affair.”
(Qur’an 33:36)
These verses demonstrate that the revealed text is final and cannot be overridden by human reasoning or personal preference.
7.4 The Sunnah Itself Is Subordinate to the Qur’an
Although Sunnah is the second most authoritative source, it serves to:
- clarify the Qur’an,
- specify its general commands,
- and apply its principles.
The Prophet (peace be upon him) never issued a command contradicting the Qur’an. This is because:
“He does not speak from desire; it is only revelation revealed.”
(Qur’an 53:3–4)
Thus, any narration attributed to the Prophet that contradicts the Qur’an is rejected by consensus.
7.5 Ijma’ Must Be in Line with the Qur’an
Scholarly consensus is only valid when it is:
- based on Qur’anic guidance,
- not contradicting any explicit verse.
A consensus that contradicts the Qur’an is automatically invalid because:
- ijma’ itself derives its authority from the Qur’an (4:59),
- and scholars cannot agree on an error that opposes revelation.
7.6 Qiyās and Other Juristic Tools Cannot Oppose Qur’anic Text
Qiyās (analogy), istiḥsān (juristic preference), maṣlaḥah (public interest), and even local customs (‘urf) are all secondary tools.
They operate only where the Qur’an is silent.
If any analogy or reasoning contradicts an explicit Qur’anic ruling, it is discarded. This principle is expressed by Imam al-Shāfi‘ī:
“If a Sunnah or qiyās contradicts the Book of Allah, we discard it and follow the Book.”
(al-Risālah)
7.7 Examples Illustrating the Principle
The Prohibition of Riba (Interest)
The Qur’an explicitly forbids riba (2:275–279).
Therefore:
- no scholar may legalize interest through reasoning,
- no qiyās can justify its permissibility,
- no custom (‘urf) can override the prohibition.
Inheritance Shares
The Qur’an precisely defines inheritance portions (4:11–12).
Therefore:
- ijma’ cannot alter the assigned shares,
- no state or scholar can adjust them contrary to the Qur’an.
Fixed Penal Rulings
Where the Qur’an legislates a fixed penalty—such as for theft (5:38)—juristic reasoning cannot nullify or alter it.
7.8 The Scholarly Consensus on This Principle
All Sunni and Shi‘i schools of law unanimously affirm that:
- The Qur’an is the supreme authority
- All legal sources must conform to it
- Anything contradicting it is invalid
Imam Abu al-Khattab al-Hanbali observes in his classical work Al-Tamheed:
فأما نسخ القرآن بالسنة المتواترة فقال شيخنا لا يجوز ذلك شرعاً، ويجوز عقلاً. (إلا أن) أحمد قال في رواية الفضل بن زياد وأبي الحارث: لا ينسخ القرآن إلا قرآن يجيء بعده، والسنة تفسر القرآن، فظاهره أنه منع من نسخه شرعاً وعقلاً وبه قال الشافعي
“As for the abrogation of the Qur’an by a mutawātir Sunnah, our Shaykh said: It is not permissible in the Sharī‘ah, although it is rationally possible. However, Aḥmad (ibn Ḥanbal) said — in the narration of al-Faḍl ibn Ziyād and Abū al-Ḥārith — that: ‘The Qur’an is not abrogated except by another Qur’an that comes after it, and the Sunnah only explains the Qur’an.’
Its apparent meaning is that he (Imām Aḥmad) prohibited such abrogation both in Sharī‘ah and in reason. Al-Shāfi‘ī also held this view.” [Al-Tamheed: Vol.2, P.369]
Where naskh and “over-ruling” overlap
There is one conceptual similarity:
- Both remove the legal effect of an earlier ruling.
- Both replace it with a new ruling.
Thus in a functional sense, one might say:
“The later Qur’anic ruling over-ruled (i.e., abrogated) the earlier one.”
But this is purely descriptive, not procedural.
The principle that “no secondary source can overrule the Qur’an” is fundamental to Islamic legal theory.
It is grounded in:
- the divine status of the Qur’an,
- explicit Qur’anic commands,
- the practice of the Prophet,
- and unanimous scholarly agreement.
Secondary sources—Sunnah, ijma’, qiyās, custom, and reasoning—exist to serve the Qur’an, not to challenge or supersede it. The Qur’an remains the supreme criterion and the highest legal and moral authority in Islam.
Conclusion
The Qur’an stands as the supreme constitutional document of Islam and the foundational source of Islamic law. It contains direct legal injunctions, universal ethical principles, and a framework for deriving rulings through scholarly interpretation. Its legislative authority is affirmed by numerous Qur’anic verses and upheld through the consensus of classical and modern jurists alike. Through a combination of precise rulings and broad principles, the Qur’an remains a dynamic and adaptable source of law applicable across time and cultures. Its primacy in the legal hierarchy ensures that all secondary sources—Sunnah, ijmā‘, and qiyās—derive their legitimacy from it and operate within its authoritative framework.
Islamic scholars, using sophisticated interpretive methodologies, ensure that the Qur’an’s guidance remains applicable across eras. Its universality and adaptability reflect its divine origin and make it the enduring constitution of Muslim life.
The Qur’an therefore functions not merely as scripture but as a living constitution that shapes jurisprudence, moral philosophy, governance, and the spiritual and social lives of Muslims across centuries.
