Sources of Muslim Law — Primary Sources

Quran • Sunnah • Ijma • Qiyas | Foundational Notes for RJS, DJS & PCS-J

1. Introduction

Muslim Law — also called Mohammedan Law or Islamic Personal Law — is the body of rules derived from the Islamic religion that governs the personal relations of Muslims in matters such as marriage, divorce, dower, maintenance, guardianship, succession, gifts and wakf. Unlike Hindu Law, which underwent extensive codification after independence, a very large portion of Muslim Law in India remains uncodified and continues to be administered on the basis of its original religious sources as interpreted by courts over nearly two centuries.

For a judicial aspirant, understanding the sources is not merely theoretical — it is the lens through which every Muslim-law question (a talaq, a dower claim, a wakf dispute) must finally be answered. When statute is silent (as it often is), the judge returns to the original sources to ask: what does the Quran say? If silent, what is the Sunnah? If silent, is there Ijma? Only then, Qiyas. This hierarchy controls the reasoning.

Islamic jurists traditionally classify the sources of Muslim law into two broad categories — Primary (original, divine) Sources and Secondary (derivative, human) Sources. This article covers the four Primary Sources exhaustively. Secondary sources (custom, legislation, judicial precedent, equity, istihsan, istislah) are treated in Topic 2 of this module.

2. Meaning of 'Sources of Law' — Formal vs Material

The term 'source of law' is used in two senses in jurisprudence:

1. Formal source — that which gives binding force and validity to the rule (for Muslim law, the sovereign Will of Allah as revealed and manifested).
2. Material source — the concrete material from which the actual rules are derived (Quran, Sunnah, Ijma, Qiyas).

When we speak of 'sources of Muslim law' in a legal-studies context, we refer primarily to the material sources. Sir Abdur Rahim classified them into two — Original (Usul) and Derivative; this roughly maps to Primary and Secondary.

Distinction — Primary vs Secondary

3. The Four Primary Sources — An Overview

Islamic jurisprudence (Fiqh) identifies four primary sources, traditionally listed in descending order of authority:

1. The Quran (Qur'an) — the divine revelation.
2. The Sunnah — the prophetic tradition (words, deeds, tacit approvals of the Prophet Muhammad).
3. Ijma — the consensus of Muslim jurists on a legal question.
4. Qiyas — analogical deduction from the earlier three sources.

Imam Shafi, founder of the Shafi school, was the first to systematise this fourfold scheme in his treatise 'Ar-Risala'. It has since been accepted as the standard classification across the four Sunni schools. The Shia Ithna Ashari school accepts Quran and Sunnah but rejects Ijma of the Companions and Qiyas in the Sunni sense, substituting Aql (reason) as the fourth source — an important point for exam purposes.

I. The Quran — The Supreme Source

1. Meaning and Etymology

The word 'Quran' is derived from the Arabic root 'qara'a' meaning 'to read' or 'to recite'. Literally, therefore, it means 'The Recitation'. It is the holy book of Islam, believed by Muslims to be the direct, verbatim Word of Allah revealed to Prophet Muhammad through the Archangel Gabriel (Jibreel) over a period of approximately 23 years (610–632 AD), first at Mecca and later at Medina.

After the Prophet's death (632 AD), the revelations — which had been preserved in memory by the huffaz (memorisers) and written on assorted materials — were compiled into a single manuscript during the caliphate of Abu Bakr and standardised into an official codex (mus'haf) during the caliphate of Uthman around 650 AD. This 'Uthmanic recension' is the text universally followed by Muslims today.

2. Composition and Structure

• Chapters: 114 suras (chapters), arranged not chronologically but broadly in decreasing order of length.
• Verses: approximately 6,236 ayats (verses) in total, depending on counting method.
• Division: Meccan suras (revealed before migration, 610–622 AD) deal largely with theology, ethics and eschatology; Medinan suras (622–632 AD) contain the bulk of legal and social regulation.
• Legal verses (Ayat-ul-Ahkam): out of ~6,236 verses, only about 200–250 contain legal rules (jurists' estimates vary: Ghazali ~500, Shafi ~200). These are the verses of direct relevance to the lawyer.

3. Classification of Quranic Legal Verses

Muslim jurists have classified the legal provisions of the Quran for ease of study. The standard classification by subject-matter yields roughly the following breakdown of the Ayat-ul-Ahkam:

4. Verses of First-Order Relevance to Muslim Personal Law

A few representative legal verses every judicial-services aspirant should be able to recall by reference:

• Sura Baqarah 2:228 — iddat (waiting period) of three menstrual cycles for divorced women.
• Sura Baqarah 2:229–230 — manner and consequences of talaq; halala.
• Sura Nisa 4:3 — permission of polygamy up to four wives, conditional on equal treatment.
• Sura Nisa 4:4 — mandatory dower (mehr) as the bride's absolute property.
• Sura Nisa 4:11–12 & 4:176 — the Quranic law of inheritance; fixed shares of relations.
• Sura Nisa 4:35 — appointment of arbitrators in matrimonial disputes — foundation of modern family-court thinking.
• Sura Nisa 4:129 — practical impossibility of equal treatment among co-wives.
• Sura Talaq 65:1–7 — entire Sura devoted to procedure of divorce.

5. Authority of the Quran

The Quran stands at the absolute apex of Muslim law. No rule may contradict a clear (qat'i) verse of the Quran. Sunnah supplements and explains the Quran but cannot abrogate it; Ijma and Qiyas must yield to Quran. This hierarchical supremacy is universally accepted across Sunni and Shia schools.

II. The Sunnah — The Prophetic Tradition

1. Meaning — Sunnah and Hadith Distinguished

'Sunnah' is an Arabic word meaning 'path', 'way' or 'established practice'. In Islamic jurisprudence, it refers to the normative model behaviour of Prophet Muhammad — his words, acts and silent approvals. It is the second primary source of Muslim law.

'Hadith' literally means 'narration' or 'report'. Hadith is the written record of a Sunnah: the linguistic vehicle that preserves the practice. In short — Sunnah is the substance; Hadith is the form. Every Hadith conveys a Sunnah; a valid Sunnah is one that is ultimately traceable through authentic Hadith.

2. Classification of Sunnah

The Sunnah is traditionally classified into three kinds according to the form in which the Prophet's conduct was manifested:

1. Sunnat-ul-Fail (Sunnah of deed) — the acts done by the Prophet, e.g., the manner of performing ablutions or prayer.
2. Sunnat-ul-Qaul (Sunnah of word) — the sayings and express instructions of the Prophet.
3. Sunnat-ul-Taqrir (Sunnah of silent approval) — acts done by others in the Prophet's presence which he observed and did not forbid, thereby tacitly approving them.

3. Structure of a Hadith — Isnad and Matn

Every Hadith consists of two parts:

• Isnad (chain) — the chain of transmitters by whom the report has come down: 'A heard from B who heard from C… who heard from the Prophet.' Authenticity of the chain is fundamental.
• Matn (text) — the actual words of the Prophet or description of his act.

Islamic scholarship has developed a rigorous science (Ilm-ar-Rijal — 'biography of the narrators') to examine the reliability of every link in the isnad, producing graded categories of authenticity.

4. Classification of Hadith by Authenticity

A further classification by transmission

• Mutawatir — narrated by such a large number of people in every generation that collusion in falsehood is impossible. Highest authenticity; equivalent to certainty.
• Mashhur — well-known, narrated by two or more companions and then widely; presumed authentic.
• Ahad (solitary) — reported by one or a few narrators; presumption in favour but not conclusive.

5. The Six Canonical Sunni Collections — Kutub al-Sittah

6. Authority of the Sunnah

The Quran itself commands obedience to the Prophet: "Whoever obeys the Messenger has obeyed Allah" (Sura Nisa 4:80) and "Take what the Messenger gives you, and refrain from what he forbids" (Sura Hashr 59:7). These verses furnish the Quranic foundation for the binding authority of the Sunnah.

As a matter of legal technique, the Sunnah performs three functions: (i) it confirms rules in the Quran, (ii) it explains and elaborates general Quranic rules, and (iii) it supplements the Quran by establishing additional rules on matters where the Quran is silent (e.g., specific rules of inheritance for the grandmother).

III. Ijma — Consensus of Jurists

1. Meaning and Basis

'Ijma' literally means 'agreement', 'consensus' or 'determination'. In Islamic jurisprudence it signifies the agreement of the Muslim jurists (mujtahidun) of any particular age upon a question of law. It operates where the Quran and Sunnah are silent or ambiguous, and serves as the chief device by which Islamic law has evolved to meet new situations in every generation after the Prophet.

The classical doctrinal basis for Ijma is the Hadith: "My community will never agree in error" (la tajtami'u ummati 'ala dalalatin). This is supplemented by Quranic verses enjoining consultation (shura) and the obligation to follow the path of believers (Sura Nisa 4:115).

2. Classification of Ijma

1. Ijma of the Companions (Ijma-as-Sahaba) — the consensus of the Prophet's Companions. Regarded as highest-authority Ijma by all Sunnis. The Shia Ithna Ashari school does not regard this as independently binding.
2. Ijma of the Jurists (Ijma-ul-Mujtahideen) — consensus of qualified jurists of any later age on a question of law. This is the operative form of Ijma in practice.
3. Ijma of the People (Ijma-ul-Ummah) — consensus of the common folk on matters of daily religious practice (e.g., five daily prayers). Of theological rather than juristic importance.

3. Essentials of a Valid Ijma

• The consensus must be of qualified mujtahids (jurists competent to exercise independent legal reasoning — ijtihad).
• It must be on a legal question (not a purely factual or theological matter).
• It must be unanimous among the mujtahids of that age (not merely a majority — though later scholars admit a near-unanimous view).
• It must not contradict the Quran or an established Sunnah.
• It must relate to the era of mujtahids — i.e., one of the generations in which qualified scholars existed.

4. Binding Force and Revocability

Once a valid Ijma is established, all later Muslims are bound by it. The prevailing Sunni view is that Ijma cannot be revoked by a later Ijma: the door of ijtihad on that question is regarded as closed. This is itself controversial — modern reformists argue ijtihad can be reopened — and Indian courts have shown willingness to reconsider rules where evolving social conditions demand it.

5. Ijma in Indian Courts

Indian courts, in the absence of any constitutional mechanism to convene contemporary Ijma, treat authoritative classical Ijma as evidence of Muslim law. Commentaries like Hidayah (Burhan al-Din al-Marghinani) and Fatawa-i-Alamgiri (compiled under Aurangzeb) are used as records of settled Ijma and have been cited innumerable times from the Privy Council down to the Supreme Court.

IV. Qiyas — Analogical Deduction

1. Meaning

'Qiyas' literally means 'measurement' or 'comparison'. Juristically, it is the process of deducing a rule of law for a new case by reasoning from an existing rule in the Quran, Sunnah or Ijma that rests on the same effective cause. It is the last of the four primary sources and stands as the chief engine of legal reasoning in Sunni jurisprudence.

Example: The Quran prohibits wine (khamr) because it intoxicates. By Qiyas, modern narcotic drugs — which share the effective cause (intoxication / impairment of reason) — are held prohibited, even though they are not mentioned by name in the Quran. The analogy works because the underlying illah (cause) is the same.

2. The Four Pillars (Arkan) of Qiyas

3. Essentials / Conditions of a Valid Qiyas

• The original case (asl) must be founded on a Quranic verse, Sunnah or Ijma — never on another Qiyas.
• The rule (hukm) of the original case must still be in force and must be a shar'i rule (a rule of Islamic law).
• The illah (effective cause) must be ascertainable and not arbitrary; it must be a quality capable of being shared by other cases.
• The illah must be common to both the original and the new case.
• The rule arrived at by Qiyas must not contradict a clear Quranic text or Sunnah.

4. Shia Position on Qiyas

The Shia Ithna Ashari school rejects Qiyas as a source of law, regarding it as speculative and liable to abuse. They hold that the Quran and the teachings of the infallible Imams cover every legal question, and that reason (Aql) — informed by those two sources — takes the place of Qiyas. This is a high-priority exam-point: whenever a question lists 'Qiyas' as a Shia source, it is wrong.

5. Significance of Qiyas in Modern Times

Qiyas has proved indispensable for applying a seventh-century revelation to twenty-first-century problems. Bank interest, organ transplantation, artificial insemination, intellectual-property protection, environmental regulation — none is textually addressed in the Quran or Sunnah, yet each has been addressed by modern jurists through systematic Qiyas. For an Indian judicial officer, awareness of this flexibility is important when reading fatwas tendered as evidence of Muslim law.

V. Hierarchy and Interplay of the Primary Sources

The four primary sources do not operate at the same level. They form a strict pyramid:

Thus, the judge proceeds from top to bottom. Only if the Quran is silent will the Sunnah be consulted; only if the Sunnah is silent will Ijma be examined; only if Ijma is absent will Qiyas be attempted. This ordering is not just theoretical — it is the actual chain of reasoning relied upon by all four Sunni schools (with slight variations in emphasis: Hanafis lean more readily on Qiyas, Malikis on the practice of Medina, Shafi on Sunnah after Quran, Hanbalis on Hadith most strictly).

Mnemonic for Hierarchy

VI. Landmark Cases — Ratio Decidendi at a Glance

1. Aga Mahomed Jaffer Bindaneem v. Koolsom Beebee, (1897) 24 IA 196 (PC)

Facts: Dispute concerning a Shia widow's claim to mahr and maintenance. The High Court had applied ideas of equity to qualify the Shia rule.

Held: The Privy Council, speaking through Lord Hobhouse, reversed. It is not permissible for Indian courts to refuse effect to established rules of Muslim law on the ground that they are opposed to justice, equity or good conscience.

Ratio: Muslim Personal Law, so far as it is expounded in the recognised authoritative texts, must be applied as it stands; judges cannot rewrite it on equitable grounds.

Significance: Anchors the primacy of the original sources (Quran, Sunnah, Ijma, Qiyas as transmitted through authoritative fiqh) in Indian jurisprudence.

2. Baker Ali Khan v. Anjuman Ara Begum, (1903) 30 IA 94 (PC)

Ratio: It is not the duty of the Court to speculate upon the correctness of Muhammadan Law as laid down in the classical texts; courts must administer the law as found in its recognised books. Effectively froze judicial ijtihad in India.

3. Hamira Bibi v. Zubaida Bibi, (1916) 43 IA 294 (PC)

Facts: Claim by a Muslim wife for unpaid dower and interest thereon.

Ratio: The Privy Council held that the rules of Muslim law must be drawn from the Quran, the Sunnah and the classical jurists; interest on dower can be awarded in appropriate circumstances as a matter of equity as known to Muslim law itself, not English equity. The judgment illustrates the interplay of primary sources with equitable principles internal to Islamic jurisprudence.

4. Mohd. Ahmed Khan v. Shah Bano Begum, (1985) 2 SCC 556

The Constitution Bench referred extensively to Quranic verses — particularly Sura Baqarah 2:241 — to hold that a divorced Muslim woman is entitled to maintenance under Section 125 CrPC. Significance: confirms that Indian constitutional courts will and do engage directly with the Quran (the supreme primary source) when interpreting Muslim personal law, subject of course to the overriding Constitution.

5. Danial Latifi v. Union of India, (2001) 7 SCC 740

A Constitution Bench read down the Muslim Women (Protection of Rights on Divorce) Act 1986 to secure a reasonable and fair provision to the divorced Muslim wife extending beyond iddat, relying on the spirit of the Quranic verses identified in Shah Bano. Significance: demonstrates the Supreme Court's method of interpreting statute harmoniously with the primary source (Quran), rather than in conflict with it.

6. Shayara Bano v. Union of India, (2017) 9 SCC 1

Though better known for striking down instant triple talaq (talaq-e-biddat), the majority and minority judgments all drew extensively on Quranic verses, Hadith and classical Hanafi Ijma, reaffirming that the primary sources remain the starting point for any judicial appraisal of a Muslim law rule — with the Constitution as the outer limit.

VII. Shia vs Sunni — Key Differences on the Primary Sources

VIII. Exam Corner — High-Yield Points

Model Questions for Practice

1. Enumerate and critically examine the primary sources of Muslim law. Which of these is accepted by both the Sunni and the Shia schools? (Long answer — 15 marks)
2. Distinguish between Sunnah and Hadith. Explain the classification of Hadith by authenticity. (Short note — 10 marks)
3. "Qiyas is the fourth source of Muslim law but it is the first source of its growth." Examine this statement with examples. (Essay — 20 marks)
4. What is Ijma? Discuss its kinds and essential conditions. Has Indian law recognised Ijma as a continuing source? (10 marks)
5. Mcq: Which of the following is NOT a primary source of Muslim law? (a) Qiyas (b) Sunnah (c) Istihsan (d) Ijma. Answer: (c) Istihsan.

IX. Conclusion

The four primary sources of Muslim law — Quran, Sunnah, Ijma and Qiyas — together constitute the architecture on which every rule of Mohammedan Law in India ultimately rests. The Quran supplies the divine bedrock; the Sunnah authoritatively explains and supplements it; Ijma fills gaps through the collective wisdom of jurists; and Qiyas extends the corpus to new situations by disciplined analogical reasoning.

For the Indian judge — and for the judicial-services aspirant — these sources are not museum pieces. They are invoked almost every time a Muslim-law issue reaches the courts: from a widow's claim to maintenance, through the validity of a particular form of talaq, to a dispute about wakf or succession. The Privy Council's early rulings (Aga Mahomed Jaffer, Baker Ali Khan) and the Supreme Court's later pronouncements (Shah Bano, Danial Latifi, Shayara Bano) show a continuous engagement with the primary sources within the outer limits set by the Constitution of India. A lawyer who cannot locate a rule in its primary source cannot defend it — and will find it difficult to distinguish it. Mastery of Topic 1 is therefore the foundation for every later topic in Muslim law.

X. Frequently Asked Questions

Q1. How many primary sources does Muslim law recognise?

Four — Quran, Sunnah, Ijma and Qiyas. All four are accepted by the Sunni schools. The Shia Ithna Ashari school accepts only the first two in the usual sense and substitutes Aql (reason) for Qiyas, while giving Ijma a narrower role.

Q2. Is the Quran codified law?

No. The Quran is a religious scripture regarded as the direct Word of Allah. It is not a statute enacted by any legislature, but its legal verses are treated by Indian courts as authoritative sources of Muslim personal law (to be applied subject to the Constitution).

Q3. What is the difference between Sunnah and Hadith?

Sunnah is the practice itself — what the Prophet did, said or tacitly approved. Hadith is the written record of that practice. Every Hadith conveys a Sunnah; Sunnah is the substance and Hadith is the form.

Q4. Why do Shias reject Qiyas?

The Shia Ithna Ashari school holds that the teachings of the twelve infallible Imams, together with the Quran and Sunnah, cover every legal question. Analogical reasoning, being speculative, is seen as a human guess that could err; hence Aql (structured reasoning consistent with revelation) takes its place.

Q5. Can Indian courts create a new rule of Muslim law by fresh Ijma?

As a matter of institutional competence, no — Indian courts apply Muslim law as found in the authoritative texts (Baker Ali Khan). Reform comes through legislation (e.g., Shariat Act 1937, DMMA 1939, MW(PRD) Act 1986, MW(POMRMA) Act 2019) or by constitutional invalidation (Shayara Bano). A contemporary Ijma of Muslim jurists in India is, at best, persuasive evidence of current law.

Q6. Which is the most authentic Hadith collection?

Sahih al-Bukhari is generally regarded as the most authentic, followed closely by Sahih Muslim. Together these two are called 'Sahihayn' (the two Sahihs) and are accorded the highest probative value among Sunni Muslims.

Q7. What is Ayat-ul-Ahkam?

Ayat-ul-Ahkam (literally 'verses of rulings') refers to those Quranic verses which contain legal rules. Out of approximately 6,236 verses of the Quran, classical jurists identify around 200 to 500 as legal verses — the rest being theological, ethical or narrative in nature.
