Introduction — Sources of Muslim Law (Quran, Sunna, Ijma, Qiyas)

Muslim personal law applied by Indian courts is not a single statute. It is a layered body of doctrine drawn from four classical sources — the Quran, the Sunna, Ijma and Qiyas — refined through centuries of juristic interpretation, altered at the margins by customary practice, and bounded in India by the Muslim Personal Law (Shariat) Application Act, 1937. Every chapter of the subject opens by asking which source supplies the rule and whether an Indian statute or judicial decision has displaced it. The full subject map sits at the Muslim Law notes hub; this opening chapter sets the source-architecture that every subsequent chapter relies on.

The architecture matters for the exam-aspirant. When a question asks about the validity of a marriage, the legitimacy of a child, or the enforceability of a gift, the answer turns on whether the proposition rests on a Quranic verse, a hadith, a juristic consensus, an analogical extension, a surviving custom, or a statutory overlay such as the 1937 Act, the Dissolution of Muslim Marriages Act, 1939, or the Muslim Women (Protection of Rights on Marriage) Act, 2019. Source-identification is the first move; doctrine-application is the second.

What Indian courts actually apply

Indian courts apply Muslim law to Muslims only in some matters, not all. The rules of Mahomedan law fall into three divisions. First, those expressly directed by the Legislature to be applied — most importantly succession and inheritance, and through the 1937 Act the matters discussed in application of Muslim personal law in India. Second, those applied to Muslims as a matter of justice, equity and good conscience — for example, the Muslim law of pre-emption in jurisdictions where it has not been displaced by special legislation. Third, those that are not applied at all though the parties are Muslims — Mahomedan criminal law and the Mahomedan law of evidence, which have been wholly replaced by the Indian Penal Code, the Code of Criminal Procedure, the Indian Evidence Act, and now their successor codes.

This three-fold division explains why the same Muslim litigant will be governed by Muslim law for marriage, dower and inheritance but by the general law of the land for criminal liability or evidentiary presumptions. The duty of the court, in cases of Hindu or Mahomedan law, is to interpret the law and not to depend upon the opinion of experts however learned — a proposition the Privy Council reaffirmed in Shahid Ganj v. Gurdwara Parbandhak Committee. Source-grounding is therefore a judicial exercise, not a clerical one.

The same source-discipline carries across the cognate chapters. Whether the question concerns the essentials of nikah, the kinds of sahih, batil and fasid marriages, or the operation of iddat, the analytical first move is to ask which source supplies the rule. A Quranic verse and a customary practice cannot stand at the same level; nor can a Hanafi position and a Shia divergence. Building the habit at the level of sources spares the aspirant from running into doctrinal contradictions later in the syllabus.

The Quran — the primary source

The Quran is the principal source of Muslim law. It is treated by the jurists as the literal word of God revealed to the Prophet, organised into 114 surahs and roughly 6,000 verses, of which a much smaller subset — variously estimated at 200 to 600 — carries strictly legal content. The legal verses concern marriage, divorce, inheritance, dower, polygamy, the iddat period, parental obligations, contracts, gifts and the prohibition of usury. The non-legal verses, which deal with theology, eschatology and ethics, supply moral framing but are not directly cited as positive rules in court.

The Quran is the supreme textual authority. No rule of Sunna, Ijma or Qiyas may contradict an unambiguous Quranic injunction. Where Quranic wording is express and unambiguous (qat'i al-dalalah), the rule is settled and not open to juristic disagreement. Where the wording is general or capable of more than one reading (zanni al-dalalah), the jurists invoke the secondary sources to determine the operative rule — which is why the same Quranic verse can produce different positions in the Hanafi, Shafi'i, Maliki, Hanbali and Ithna Ashari schools.

The 1937 Act recognises the Quran indirectly. Section 2 makes the Muslim Personal Law (Shariat) the rule of decision in enumerated matters where the parties are Muslims; the Quran is the foundational layer of that personal law. The Act's drafters did not enumerate the Quran as such — they enumerated the substantive subjects (marriage, divorce, dower, maintenance, gifts, inheritance, wakfs and so on) and left the source-hierarchy to the courts.

The Sunna — the Prophet's practice

The Sunna is the second source. It comprises the sayings (qaul), actions (fi'l) and tacit approvals (taqrir) of the Prophet, transmitted through chains of narration and recorded in the canonical hadith collections. Where the Quran is silent or general, the Sunna supplies the operative detail. The classical example is salat (prayer) — the Quran commands the duty, the Sunna prescribes the form. In the legal context, the Sunna fills in marriage formalities, the procedure of talaq, the rules of acknowledgment of paternity, and the evidentiary standards for legitimacy.

For courts in India, the Sunna is not directly cited from hadith collections. It enters the legal record through classical commentaries — the Hedaya, Baillie's Digest, the Fatawa-i-Alamgiri, the Sharai-ul-Islam — which collate hadith-grounded rules and present them as black-letter doctrine. When an Indian judgment refers to a rule of Mahomedan law, the citation chain typically runs hadith → classical commentator → Indian textbook → judicial dictum. The Sunna is therefore a hidden layer; it shapes outcomes through doctrinal lineage rather than direct quotation.

Sunni and Shia schools differ on which hadith are authoritative. The Sunni schools accept the six canonical Sunni collections; the Ithna Ashari Shias rely on a separate corpus traceable through the Imams. Because most Indian Muslims are Hanafi Sunnis, the presumption in Akbarally v. Mahomedally is that a Sunni is governed by Hanafi law unless a Shia identification is established — a presumption that channels which Sunna-derived rule applies.

Ijma — juristic consensus

Ijma is the consensus of the qualified jurists (mujtahidun) of a particular generation on a point of law. Its theoretical justification comes from the Prophetic saying that the Muslim community will not agree upon error, and the operative claim is that once consensus is reached on a question — for example, that the iddat of a widow is four months and ten days, or that a marriage solemnised without witnesses is irregular but not void — that consensus binds later generations.

Ijma is the source through which classical Muslim jurisprudence achieves doctrinal stability across the centuries. It is also the source through which the four Sunni schools and the Shia schools diverge — because what counts as consensus depends on which jurists are recognised. The Hanafi school recognises the consensus of the Companions and of subsequent generations of Hanafi jurists; the Maliki school accords particular weight to the practice of the people of Medina; the Shafi'i school adheres closely to texts and is more cautious about consensus; the Ithna Ashari Shias confine binding consensus to the views of the Imams.

For the Indian aspirant, the practical takeaway is that when a textbook describes the rule as "settled" or "well-established by the ancient expositors", the underlying source is ijma. As the Allahabad Full Bench observed in Mohd. Ismail v. Abdul Rashid, where a rule of Mahomedan law is well-settled in the view of the ancient expositors thereof, it is not open to the court to disregard or reject it on the ground that it is illogical or unsound — provided it is not contrary to justice, equity and good conscience.

Qiyas — analogical reasoning

Qiyas is the extension of a textual rule to a new fact-pattern through analogical reasoning. Where the Quran or Sunna addresses a situation but a new situation arises that is not directly covered, qiyas asks whether the new situation shares the operative cause (illah) of the textual rule. If it does, the rule is extended; if it does not, the rule is not extended. The classical example is the prohibition of intoxicants — the Quran prohibits khamr (wine made from grapes), and qiyas extends the prohibition to other intoxicants on the ground that intoxication is the operative cause.

Qiyas occupies an awkward place among the Sunni schools. The Hanafi and Shafi'i schools accept it as a primary source; the Maliki school accepts it but subordinates it to the practice of Medina; the Hanbali school is the most cautious about it; the Zahiri school (now extinct) rejected it altogether. The Ithna Ashari Shias replace qiyas with aql (reason) as a source — the practical effect is similar but the theoretical anchor is different.

For the exam, the key point is that qiyas is the source through which classical doctrine accommodates novel fact-patterns. When a Hanafi rule extends to a transaction that the Quran and Sunna did not contemplate — for example, modern banking instruments, or nikah by phone, video conference or internet — the extension is achieved through qiyas. The validity of the extension turns on whether the operative cause in the textual rule is genuinely present in the new fact-pattern.

Custom (urf) and the Shariat Act, 1937

Classical Muslim jurisprudence recognises custom (urf or adat) as a subsidiary source where it does not contradict the Quran, Sunna or settled doctrine. In India, custom did much heavier work before 1937. The Bengal, Agra and Assam Civil Courts Act, 1887, the Madras Civil Courts Act, 1873, the Bombay Regulation IV of 1827, the Punjab Laws Act, 1872, the Central Provinces Laws Act, 1875, the Oudh Laws Act, 1876, and the Ajmer Laws Regulation, 1877, all permitted Muslims to plead and prove custom in derogation of Mahomedan law. The result was that customary law of agnatic succession excluded females, customary law in Punjab departed from the iddat rules, and Khoja and Cutchi Memon practice followed Hindu rules of inheritance.

The Muslim Personal Law (Shariat) Application Act, 1937, was the corrective. Section 2 makes the Muslim Personal Law (Shariat) the rule of decision in cases where the parties are Muslims for ten enumerated matters: intestate succession, special property of females, marriage, dissolution of marriage (including talaq, ila, zihar, lian, khula and mubarat), maintenance, dower, guardianship, gifts, trusts and trust properties, and wakfs (other than charities and charitable institutions and charitable and religious endowments). The Act expressly opens with "Notwithstanding any custom or usage to the contrary". The phrase abrogates custom in those enumerated subjects.

Two important exceptions survive. The Act excludes agricultural land from its operation, leaving customary law in force where it had previously applied to such land. And section 3 of the Act allows a Muslim to make a declaration extending the Act to adoption, wills and legacies — a declaration that, as the Lahore High Court noted in Ata Mohammad v. Mohammad Shafi, operates retrospectively. Section 6 repeals the relevant clauses of the pre-1937 statutes only sub modo — to the extent of inconsistency — so the older statutes still govern matters outside section 2 (notably agricultural land).

Statutory overlays

The 1937 Act is the architectural anchor, but several other Indian statutes layer on top of it and sometimes override the classical sources. The Dissolution of Muslim Marriages Act, 1939, supplies a statutory list of grounds on which a Muslim wife may obtain a decree dissolving her marriage. The Muslim Women (Protection of Rights on Divorce) Act, 1986, regulates maintenance after divorce and was constitutionally read down in Daniel Latifi v. Union of India. The Muslim Women (Protection of Rights on Marriage) Act, 2019, criminalises pronouncement of instant triple talaq following the constitutional verdict in Shayara Bano v. Union of India. The Wakf Act, 1995, codifies the law of wakfs.

For each statute, the question for the source-analyst is the same: does the statute displace, alter or supplement the classical rule? The Dissolution of Muslim Marriages Act, 1939, supplements — it adds a statutory route to divorce alongside the classical modes of khula and mubarat. The 2019 Act displaces — it criminalises a practice that, before Shayara Bano, the Hanafi school treated as effective though sinful. The Wakf Act, 1995, codifies — it largely captures the classical doctrine while adding registration, regulation and a Wakf Board structure.

Hierarchy of sources — the decision sequence

When an Indian court is asked to decide a question of Muslim personal law, the analytical sequence runs in this order. First, is there an Indian statute on point? If yes, the statute governs (subject to constitutional reading-down where required). Second, if there is no statute, does the Muslim Personal Law (Shariat) Application Act, 1937, channel the court to the Shariat? If yes, the Shariat is the rule of decision. Third, within the Shariat, what is the school of the parties — Sunni Hanafi (default), Sunni Shafi'i (more common in Kerala and Malabar), or one of the Shia sub-sects? Fourth, within that school, what does the Quran say? Fifth, what does the Sunna add? Sixth, what is the position of the classical jurists by ijma? Seventh, does the rule extend to the present fact-pattern by qiyas? Eighth, does any surviving custom apply (in agricultural land or in matters outside section 2)?

The sequence rarely runs through every step in a single judgment, but it explains why source-grounding is so crucial. A misidentified source — for example, citing a Shia rule against a Sunni party, or citing custom against a section 2 matter — yields a misidentified rule. The Privy Council and the Indian Supreme Court have repeatedly held that the burden of proving custom in derogation of Mahomedan law lies on the party setting it up, and the proof must be ancient, certain, continuous and reasonable.

Schools and the source-question

The four Sunni schools — Hanafi, Shafi'i, Maliki, Hanbali — differ on the weight given to each source. The Hanafi school relies heavily on qiyas and on the personal opinion (ra'y) of the early jurists; the Maliki school privileges the practice of the people of Medina; the Shafi'i school is the most text-bound; the Hanbali school relies most heavily on hadith and is most cautious about ijma and qiyas. The Ithna Ashari Shia school replaces ijma of the Sunni jurists with the consensus that includes the Imams, and replaces qiyas with aql (reason). For a comprehensive treatment of how these school-divergences play out, see the chapter on schools of Muslim law.

The school-question is not academic. It controls outcomes. A marriage without witnesses is irregular under Hanafi law but valid under Shia law. A muta marriage is recognised under Shia law and unrecognised under Sunni law. The iddat rules, the rules on dower and the rules on inheritance differ materially between Sunni and Shia. Source-grounding therefore must be combined with school-identification. Source plus school equals rule.

Indian Supreme Court interventions

The Indian Supreme Court has occasionally read constitutional limits into the classical sources. In Mohd. Ahmed Khan v. Shah Bano Begum, the Court read section 125 of the Code of Criminal Procedure as supplying a maintenance remedy to a divorced Muslim woman, prompting the legislative response of the 1986 Act. In Daniel Latifi v. Union of India, the Court read the 1986 Act so as to preserve a substantive right to fair and reasonable maintenance. In Shamim Ara v. State of UP, the Court held that even a written talaq must be communicated, must be preceded by attempted reconciliation, and must state reasons. In Shayara Bano v. Union of India, the Court declared instant triple talaq unconstitutional. Each intervention illustrates the constitutional layer that now sits above the classical sources in India.

The cases that govern other doctrinal areas — gifts under hiba, dower under mahr, and the wife's statutory right to dissolution under the Dissolution of Muslim Marriages Act, 1939 — show the same pattern: classical source, juristic consensus, Indian statute, judicial reading.

Source-identification in exam answers

For the judiciary aspirant, three habits make the difference. First, name the source. When stating a rule, identify whether it rests on the Quran, Sunna, ijma, qiyas, custom or statute. Second, name the school. Indicate Hanafi (default in India) and flag Shia divergences where they are material. Third, name the statute. The 1937 Act, the 1939 Act, the 1986 Act, the 2019 Act, the Wakf Act, 1995, and the Kazis Act, 1880, between them cover most of the modern statutory overlay. A well-drafted answer signals all three layers — source, school, statute — even briefly.

The remainder of these notes carry forward this discipline. Each substantive chapter — on the essentials of marriage, on the Shariat Application Act, on the modes of talaq, on the iddat period, on Sunni inheritance, and on waqf creation and management — opens with the source, flags the school, and then sets out the rule. Together they offer the full survey of Indian Muslim personal law as it stands today.

Limits of the classical sources today

The classical four-source schema retains its theoretical primacy but works under three modern limits. First, the Constitution. Articles 14, 15, 21 and 25 constrain personal-law rules; Shayara Bano shows that a classical rule can be set aside as manifestly arbitrary. Second, statute. The 1937 Act and its successors have codified the field where they apply, narrowing the operative role of unwritten doctrine. Third, judicial precedent. Indian courts now cite each other and the Privy Council and the Supreme Court, building an Indian case-law of Muslim personal law that operates alongside the classical commentaries.

The result is a hybrid system. The Quran, Sunna, ijma and qiyas remain the doctrinal spine. The 1937 Act and its successors form the statutory overlay. Constitutional review supplies an outer limit. For the student, the discipline is to keep these layers separate while reasoning across them, and never to confuse a statutory innovation with a classical rule, a Shia divergence with the Sunni mainstream, or a regional custom with personal law.

Frequently asked questions

What are the four primary sources of Muslim law?

The four primary sources are the Quran (the literal word of God revealed to the Prophet, organised into 114 surahs), the Sunna (the sayings, actions and tacit approvals of the Prophet recorded in the hadith collections), Ijma (the consensus of qualified jurists of a generation on a point of law) and Qiyas (the analogical extension of a textual rule to a new fact-pattern sharing the same operative cause). The Quran is the supreme source; no rule of Sunna, Ijma or Qiyas may contradict an unambiguous Quranic injunction. Custom and Indian statutes operate as secondary or overlay sources.

How does the Shariat Application Act, 1937, relate to the classical sources?

Section 2 of the 1937 Act opens with "Notwithstanding any custom or usage to the contrary" and makes the Muslim Personal Law (Shariat) the rule of decision in cases where the parties are Muslims for ten enumerated subjects — intestate succession, special property of females, marriage, dissolution of marriage including talaq ila zihar lian khula and mubarat, maintenance, dower, guardianship, gifts, trusts and wakfs other than charities. The Act does not enumerate the Quran, Sunna, Ijma or Qiyas as such; it simply channels the court to the Shariat and leaves the source-hierarchy to the classical jurisprudence. Agricultural land is excluded.

Why do Indian courts apply Muslim law to some matters but not others?

Indian courts apply Mahomedan law only in the matters expressly directed by the Legislature (chiefly succession, inheritance, marriage, dower, divorce, gifts, wakfs and guardianship) and in matters where it is applied as justice, equity and good conscience (notably pre-emption in some jurisdictions). Mahomedan criminal law and the Mahomedan law of evidence have been wholly displaced by the Indian Penal Code, the Code of Criminal Procedure and the Indian Evidence Act and their successor codes. The result is that a Muslim litigant is governed by Muslim personal law for family-law questions but by general Indian law for criminal liability, evidentiary presumptions and most commercial transactions.

What is the difference between Ijma and Qiyas?

Ijma is consensus — the agreement of qualified jurists of a generation that a particular rule is correct, building doctrinal stability across the centuries. Qiyas is analogy — the extension of an existing textual rule to a new situation that shares the operative cause (illah) of the textual rule. The classical example of qiyas is the extension of the Quranic prohibition of khamr (grape wine) to all intoxicants on the basis that intoxication is the operative cause. Ijma resolves disagreement by settling a single position; qiyas creates a new position by reasoning from old to new. The Hanafi and Shafi'i schools accept both; the Hanbali school is more cautious about both; the Ithna Ashari Shias replace qiyas with aql (reason).

Does custom still play any role in Indian Muslim law after 1937?

Custom plays a residual but real role. Section 2 of the 1937 Act expressly excludes agricultural land, so customary law continues to govern Muslims in respect of agricultural-land transactions where it had previously applied. Section 6 of the Act repeals the older state laws (Bombay Regulation IV of 1827, Madras Civil Courts Act, Punjab Laws Act and so on) only sub modo — to the extent of inconsistency — so customs in subjects not enumerated in section 2 survive. The party setting up a custom in derogation of Mahomedan law bears the burden of proving it; the proof must be of an ancient, certain, continuous and reasonable practice.
