Sources of Muslim Law — Secondary Sources

Urf • Legislation • Judicial Precedent • Equity • Istihsan • Istislah

1. Introduction

After the four primary sources (Quran, Sunnah, Ijma, Qiyas) have been applied, Muslim law — especially as administered in India — takes its content also from a set of secondary or supplementary sources. These are not divine or revealed; they are man-made (custom, statute, judicial decisions) or juristic devices (istihsan, istislah) developed by the classical schools. Their authority is conditional: they operate only where the primary sources are silent, or — in the case of legislation — where the sovereign has legitimately regulated a matter through law made under the Constitution.

The practical importance of secondary sources is vast. In Indian courts, a Muslim-law case rarely begins with a Quranic verse; it begins with a statute — most often the Shariat Act 1937 or the Dissolution of Muslim Marriages Act 1939 — and proceeds to the classical texts where those statutes refer back to 'Muslim personal law'. Understanding the secondary sources is, therefore, understanding how Muslim law actually enters the courtroom.

The Six Recognised Secondary Sources

1. Urf (Custom)
2. Legislation / Statute
3. Judicial Precedent
4. Equity, Justice and Good Conscience
5. Istihsan — Juristic Preference (Hanafi)
6. Istislah / Maslaha-al-Mursalah — Public Interest (Maliki)

I. Urf — Custom as a Source

1. Meaning

'Urf' (custom) refers to the usages and practices of a community which have been followed with such regularity and over such a length of time that they acquire the force of binding rule. Classical Islamic jurisprudence itself took cognisance of pre-Islamic Arabian customs that were not incompatible with revelation and retained them as part of the legal order. Custom has, therefore, always been accepted as a supplementary source of Muslim law.

Indian courts long applied the rule laid down in the classic English case Robinson v. Mohammed Beg that a well-established custom, clearly proved, could override the text of the Quran in matters of personal law. This far-reaching rule was statutorily reversed by Section 2 of the Shariat Act, 1937, for the ten enumerated matters in that section — discussed separately in Topic 3.

2. Kinds of Urf

1. Urf-al-Amm (general custom) — custom prevailing throughout the country or community.
2. Urf-al-Khas (special / local custom) — custom confined to a particular tribe, family or locality.
3. Urf-al-Qauli (verbal custom) — the customary meaning attached to words and expressions.
4. Urf-al-Amali (active custom) — the customary course of conduct followed by people.

3. Essentials of a Valid Custom in Muslim Law

A custom, to be recognised as a source of Muslim law, must satisfy the following requirements — very similar to the classical requirements in Hindu law:

• Antiquity — it must have been in existence for a long time and must be immemorial in the sense of dating from before living memory can trace its origin.
• Continuity — it must have been followed without interruption.
• Certainty — it must be definite in terms and extent; a vague practice is no custom.
• Reasonableness — it must not be opposed to reason, morality or public policy.
• Consistency with primary sources — it must not contradict the Quran, a clear Sunnah or a settled Ijma.
• Not in derogation of statute — after 1937, it must not touch any of the ten matters listed in Section 2 of the Shariat Act unless specifically saved.

4. Effect of Section 2 of the Shariat Act, 1937

For the ten matters listed in Section 2 — 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 rule of decision in any suit between parties who are Muslims shall be Muslim Personal Law (Shariat), notwithstanding any custom or usage to the contrary. The Act effectively de-operationalised custom for these matters; classical Muslim law was restored and custom could no longer override it.

5. Leading Cases on Custom

Abdul Hussain Khan v. Bibi Sona Dero, (1917) 45 IA 10

The Privy Council held that a pre-Shariat Act custom in Sind allowing a childless widow to inherit only a life estate (and not absolute ownership as under classical Muslim law) was valid because it had been proved to exist for generations and was not contrary to any clear textual rule. Post-1937, on the matters listed in Section 2, such a custom would no longer be admissible.

Muhammad Ibrahim Rashid v. Shaikh Muhammad Ibrahim, AIR 1922 PC 59

The Privy Council restated that custom, when sufficiently proved and not repugnant to Islamic law or public policy, can be a valid source of Muslim personal law; but the burden of proving such a custom lies heavily on the party asserting it.

Cutchi Memons and Khojas — Judicial History

Before the Shariat Act and the Cutchi Memons Act, 1938, the Khojas and the Cutchi Memons — both Sunni converts from Hindu trading communities — were governed by Hindu customary law on succession. Parliament progressively applied Muslim law to them, but the cases (e.g., Cassamally v. Currimbhoy, AIR 1911 Bom 116) are leading illustrations of the interplay of custom, statute and Muslim law.

II. Legislation — The Principal Modern Source

Legislation has become the most active modern source of Muslim law. Parliament and State Legislatures have over the years enacted statutes that codify, reform or clarify Muslim personal law. Some apply exclusively to Muslims; others are general laws that impact Muslim personal matters.

1. Key Central Statutes Affecting Muslim Personal Law

2. General Statutes Applicable to Muslims

• Caste Disabilities Removal Act, 1850 — protects proprietary rights of an apostate from Islam.
• Guardians and Wards Act, 1890 — procedural law for appointment of guardians; applies to all communities including Muslims.
• Transfer of Property Act, 1882 — governs transfers of immovable property; Section 129 preserves Muslim rules of gift (hiba).
• Indian Succession Act, 1925 — generally excludes Muslims (S.58), but certain parts (e.g., probate) apply.
• Code of Criminal Procedure, 1973 / BNSS, 2023 — Section 125 CrPC / Section 144 BNSS on maintenance applies to Muslim women (Shah Bano, Shamim Ara, Danial Latifi).
• Special Marriage Act, 1954 — civil marriage option for Muslims (effects vary if opted).

3. Constitutional Position of Legislation

Legislation on personal law is competent under Entry 5 of List III (Concurrent List) of the Seventh Schedule. Article 25 (freedom of conscience) is subject to public order, morality and health, and to other fundamental rights; Article 26 preserves religious denominations' autonomy in managing religious affairs. Article 44 (Uniform Civil Code) remains a Directive Principle. Together these provisions mark the constitutional space within which Muslim-law legislation operates — a space progressively expanded by the Supreme Court from Shah Bano to Shayara Bano.

III. Judicial Precedent

1. 'Anglo-Muhammadan Law' — The Colonial Legacy

The tradition of Indian courts applying Muslim law as interpreted in English-language judgments begins with Warren Hastings' Plan of 1772, under which the East India Company undertook that in suits regarding 'inheritance, marriage and caste and other religious usages or institutions, the laws of the Quran with respect to the Mahommedans … shall be invariably adhered to.' Section 27 of the Bengal Regulation IV of 1793 continued this approach. Until 1864, native law officers called Maulvis and Qazis sat alongside English judges to advise on Islamic law; after 1864 their role was abolished and judges relied on English-language treatises.

The corpus of case-law that developed during the colonial era — part classical fiqh translated and simplified, part English reasoning grafted upon it — came to be known as 'Anglo-Muhammadan Law'. Leading treatises such as Mulla's Principles of Mahomedan Law, Tyabji's Muhammadan Law and Fyzee's Outlines of Muhammadan Law are the modern descendants of that tradition.

2. Hierarchy of Binding Authority in India Today

1. Supreme Court judgments — binding on all courts (Art. 141 of the Constitution).
2. High Court judgments — binding on subordinate courts within the respective State; persuasive elsewhere.
3. Privy Council decisions — still binding authority on matters where no subsequent SC ruling exists.
4. Commentaries (Mulla, Tyabji, Fyzee, Ameer Ali) — persuasive; routinely cited by courts as evidence of Muslim law.

3. Illustrative Landmark Decisions

Abdul Fata Mohomed Ishak v. Rasamaya Dhur Chowdhri, (1894) 22 IA 76 (PC)

The Privy Council held that a wakf-alal-aulad which gave the family the entire usufruct indefinitely with only an illusory benefit to charity was invalid as a wakf. The decision provoked an outcry among Indian Muslims and led directly to the Mussalman Wakf Validating Act, 1913 (piloted by M.A. Jinnah) — a classic example of legislation reversing a judicial precedent and of precedent's continuing role as a secondary source.

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

Discussed in Topic 1. Established that courts cannot disregard a rule of Muslim law on the ground that it is contrary to equity, justice and good conscience — but only because the primary sources determine the rule.

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

Allowed interest on unpaid dower on equitable principles internal to Islamic jurisprudence — the example of equity recognised as a subordinate source.

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

Constitution Bench upheld a divorced Muslim wife's right to maintenance under Section 125 CrPC beyond iddat. Precedent became the engine of statutory reform in the form of the Muslim Women (Protection of Rights on Divorce) Act, 1986.

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

Constitution Bench read the 1986 Act purposively to ensure reasonable and fair provision for the divorced wife extending beyond iddat. Illustrates precedent working hand-in-hand with legislation.

Shamim Ara v. State of U.P., (2002) 7 SCC 518

The Supreme Court, per Justice R.C. Lahoti, held that a mere plea of talaq in written statement does not constitute divorce; talaq must be pronounced according to a just procedure, preceded by attempts at reconciliation with two arbiters, and must be proved. A turning-point precedent that recast the procedural foundations of talaq.

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

A 3:2 majority of a Constitution Bench struck down talaq-e-biddat (instant triple talaq) as unconstitutional. Judicial precedent became the direct basis for Parliament to enact the Muslim Women (Protection of Rights on Marriage) Act, 2019.

IV. Equity, Justice and Good Conscience

Indian courts, since the Bengal Regulation III of 1793 and its successors, have had a duty to decide matters not governed by any specific rule according to 'justice, equity and good conscience'. In Muslim personal law this phrase has a narrow and carefully bounded role. The Privy Council in Aga Mahomed Jaffer warned that the English sense of equity cannot be imported to override an established rule of Islamic law. Equity can, however, operate in the interstices — for instance, to allow interest on unpaid dower (Hamira Bibi v. Zubaida Bibi) or to fashion an appropriate remedy where the classical sources are silent.

In this way, equity functions alongside Istihsan and Istislah (discussed below) as a principled method of filling gaps without displacing the primary sources.

V. Istihsan — Juristic Preference (Hanafi)

Istihsan is a doctrine developed by Imam Abu Hanifa and his followers. It literally means 'to deem something preferable'. Juristically it refers to the preference of one legal solution over another that would ordinarily be dictated by strict Qiyas, when the strict Qiyas would lead to hardship, injustice or a result contrary to public interest. It is thus a form of principled departure from analogy in favour of a more equitable rule that remains within the spirit of the Shariah.

Classic illustration: Under strict Qiyas, a contract for something not yet in existence (e.g., salam — advance payment for future crop) would be void like the sale of a non-existent thing. But such contracts are a necessity of agricultural and commercial life. Istihsan was invoked to validate salam and similar contracts.

Criticism: Imam Shafi famously rejected Istihsan, holding that "he who resorts to Istihsan legislates on his own authority." The Shafi and Hanbali schools do not formally accept Istihsan; the Hanafi and Maliki schools do, with differing degrees of rigour.

VI. Istislah / Maslaha-al-Mursalah — Public Interest (Maliki)

Istislah (from 'Islah' — to set right, to reform) means considering the public interest or the welfare of the community. It is a source distinctively developed by Imam Malik. Where there is no express text and no direct Qiyas, a rule may be adopted that promotes a legitimate public benefit (maslaha) and averts a corresponding harm (mafsadah), provided it does not contradict any clear text.

Three classical conditions:

1. The interest must be genuine, not merely imagined.
2. It must be general, not for the benefit of an individual or class.
3. It must not conflict with any definite text of the Quran, Sunnah or Ijma.

Modern application: Rules permitting compulsory medical examination of prisoners, quarantine during epidemics, or road-traffic regulations have been justified in Islamic jurisprudence on the basis of Istislah.

Distinction — Istihsan and Istislah

VII. Additional Landmark Cases on Secondary Sources

Abdul Fata Mohomed Ishak v. Rasamaya Dhur Chowdhri, (1894) 22 IA 76

Facts: A settlor created a wakf where substantially the entire income was to be enjoyed by his descendants in perpetuity with only a remote and illusory benefit to charity.

Held: Invalid as a wakf. The Privy Council said a settlement was not a wakf if the benefit to charity was merely nominal.

Ratio: A wakf under Muslim law requires a substantial, not illusory, dedication to a charitable or religious purpose.

Aftermath: The decision was widely seen as inconsistent with settled Hanafi doctrine, and led to the Mussalman Wakf Validating Act, 1913 — a primary illustration of legislation (secondary source) correcting precedent (secondary source).

Shamim Ara v. State of U.P., (2002) 7 SCC 518

Facts: Husband pleaded that he had divorced his wife by talaq. Wife denied knowledge.

Held: Mere assertion of talaq in a written statement, unaccompanied by proof of pronouncement in accordance with Islamic law and preceded by efforts at reconciliation, does not effect a valid talaq.

Ratio: The procedure of talaq must conform to the Quranic scheme — attempts at reconciliation, pronouncement in the presence of witnesses, and an ascertainable date; otherwise it is of no legal effect. A landmark decision in which judicial precedent restated classical Quranic procedure.

Javed v. State of Haryana, (2003) 8 SCC 369

Upheld a provision of the Haryana Panchayati Raj Act disqualifying candidates with more than two children, rejecting the challenge under Articles 14, 15, 21 and 25. The Court observed that polygamy is not an essential feature of Islam and that the State can legitimately legislate for family welfare. Shows how general statutes (a secondary source) can legitimately impinge on Muslim customary practice.

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

Facts: Challenge to talaq-e-biddat as unconstitutional.

Held (3:2): Talaq-e-biddat is unconstitutional. Justice Kurian Joseph relied on the primary sources (Quran 4:35, 65:1) and the Hanafi doctrine itself — which calls the practice 'bad in theology, good in law' — to declare it un-Islamic. Justice Nariman and Justice Lalit struck it down as arbitrary and violative of Article 14.

Ratio: Even an accepted Hanafi practice can be invalidated when it is inconsistent with the primary sources (Quran/Sunnah) or with the constitutional fundamental rights. A striking demonstration of the modern interaction between primary, secondary and constitutional sources.

Triple Talaq – Post-Shayara Bano Statutory Response

Parliament passed the Muslim Women (Protection of Rights on Marriage) Act, 2019, declaring instant triple talaq (talaq-e-biddat) void and making its pronouncement a criminal offence punishable with up to three years' imprisonment. Sections 3 and 4 of the Act together demonstrate legislation as a secondary source responding to a Supreme Court precedent.

VIII. Interplay Between Primary and Secondary Sources

The operational picture of Muslim law in India can be summarised thus:

1. A court first looks to the statute, if any, governing the point (Shariat Act 1937; DMMA 1939; MWA 1986; MW(PRM) 2019; Wakf Act 1995).
2. If the statute directs application of 'Muslim personal law' (as most do), the court turns to the classical rule — discovered through the primary sources, filtered through Anglo-Muhammadan precedent.
3. Where primary sources are silent, secondary sources operate in a defined order — custom (only outside the Shariat Act matters), equity, istihsan/istislah.
4. All of the above is subject to the Constitution of India, particularly Part III; hence Shayara Bano could invalidate even a settled Hanafi practice.

IX. Exam Corner

Practice Questions

1. "Custom was once a powerful source of Muslim personal law; today it is largely a spent force." Examine with reference to the Shariat Act, 1937.
2. Distinguish between Istihsan and Istislah. Why did Imam Shafi reject Istihsan?
3. "Anglo-Muhammadan Law is a blend of classical Islamic jurisprudence and English judicial reasoning." Discuss with reference to leading cases.
4. Explain the role of legislation as a modern source of Muslim personal law in India, with reference to at least three major statutes.
5. MCQ: Which of the following is NOT a Maliki contribution to Islamic jurisprudence? (a) Istislah (b) Muwatta of Imam Malik (c) Istihsan (d) Reliance on practice of Medina. Answer: (c).

X. Conclusion

Secondary sources are the working tools through which classical Muslim law — a body of rules developed in seventh-century Arabia and refined through centuries of juristic scholarship — continues to speak to twenty-first-century India. Custom once reigned supreme, until the Shariat Act of 1937 narrowed its domain; legislation has since become the most active shaper of Muslim personal law, from the 1939 Act for divorce to the 2019 Act on triple talaq; judicial precedent, carried forward from the Privy Council to the Supreme Court, continues to recast and refine rules in the constitutional light; equity, istihsan and istislah ensure that the law remains humane in the gaps left by the primary sources.

For the judicial aspirant, the lesson is twofold. First, always locate the rule in its primary source. Second, understand which secondary source — statute, precedent, custom, equity — is carrying that rule into the case at hand. Mastery of both halves is what makes a Muslim-law answer complete.

XI. Frequently Asked Questions

Q1. Is custom still a source of Muslim law in India?

Yes, but in a very restricted way. Section 2 of the Shariat Act, 1937, abrogates custom in ten enumerated matters. Outside these — including some aspects of agricultural land (varying with state amendments) and matters not listed in Section 2 — custom may still be pleaded and proved.

Q2. What is 'Anglo-Muhammadan Law'?

It is the body of Muslim personal law as applied by Indian courts during the British period and continued thereafter. It is part classical fiqh, part English-style precedent, as laid down in decisions of Indian and Privy Council courts and in leading treatises such as Mulla, Tyabji, Fyzee and Ameer Ali.

Q3. Did the Privy Council create new Muslim law?

Generally no — Baker Ali Khan v. Anjuman Ara Begum (1903) held that courts must apply the law as found in authoritative texts. However, some Privy Council rulings (notably Abdul Fata on wakf-alal-aulad) were seen by Indian Muslims as inconsistent with classical doctrine and were corrected by statute.

Q4. Can legislation override classical Muslim law?

Yes — within constitutional limits. The Shariat Act 1937, DMMA 1939, MW(PRD) Act 1986 and MW(PRM) Act 2019 all modify or codify aspects of classical Muslim law. The only limits are the Constitution itself and Article 25's protection of religious belief.

Q5. What is the difference between Ijma (primary) and judicial precedent (secondary)?

Ijma is the consensus of qualified Muslim jurists on a question of Islamic law and is a primary source. Judicial precedent is the reasoned decision of a court applying Muslim law within the Indian legal system; it is binding on lower courts under Article 141 but is a secondary source in the Islamic scheme.

Q6. Are fatwas a source of Muslim law?

A fatwa is an opinion of a Muslim jurist (mufti). In India, a fatwa is not binding on any court or citizen; the Supreme Court held in Vishwa Lochan Madan v. Union of India, (2014) 7 SCC 707, that a fatwa has no legal sanction and cannot be enforced by any authority. It is at best a piece of evidence about the state of juristic opinion.
