Introduction
Muslim law, also known as Islamic law or Sharia, governs not just religious practices but also civil and personal matters such as marriage, inheritance, divorce, contracts, and crime. Derived from divine revelation and centuries of scholarly interpretation, Muslim law is a complex and dynamic legal tradition followed by millions across the world, including India. While it functions as personal law in India under the legal pluralism system, its sources are diverse, rich, and rooted in both theology and jurisprudence.
This article explores the primary and secondary sources of Muslim law, examining how they form a coherent legal system and how they continue to evolve in contemporary times.
I. Meaning and Scope of Muslim Law
Muslim law, or Islamic law, refers to the legal and ethical code derived from the Quran and the teachings of Prophet Muhammad (peace be upon him). In India, Muslim law operates as personal law and applies to Muslims in areas such as marriage, divorce, guardianship, and inheritance. The law is rooted in Shari‘ah—the divine will of God—and its human interpretation, known as Fiqh.
While Shari‘ah is considered perfect, eternal, and divinely ordained, Fiqh represents the jurists’ efforts to interpret and apply these principles in real-world situations. This distinction allows Muslim law to be both spiritually grounded and adaptable, giving rise to multiple schools of thought that reflect different methodologies, cultural contexts, and legal reasoning.
II. Classification of Sources
The sources of Muslim law are broadly classified into primary and secondary categories.
- Primary sources are those that are divinely revealed or have a direct link to the Prophet, and they comprise the Quran, the Sunnah (the actions and sayings of the Prophet), Ijma (the consensus among scholars), and Qiyas (reasoning by analogy grounded in the Quran and Sunnah).
- Secondary sources are juristic methods and customary practices that aid in the interpretation and practical application of primary sources. These include Istihsan (juristic preference), Istislah (public interest), Urf (custom), and Ijtihad (independent reasoning). These tools allow for adaptability and contextual relevance within the framework of Islamic law.
III. Primary Sources of Muslim Law
1. The Quran
The Quran is the foremost and most sacred source of Muslim law, regarded as the literal and unaltered word of God (Allah), revealed to Prophet Muhammad over a span of 23 years. It lays down the foundation for both spiritual guidance and legal governance within Islam. Out of more than 6,000 verses, around 500 pertain to legal matters, addressing issues such as marriage and divorce (Surah An-Nisa, 4:3; 4:34), inheritance (4:11–12), criminal laws like theft (Surah Al-Ma’idah, 5:38), and commercial transactions.
These legal provisions are binding and considered final. However, the Quran often provides general principles rather than exhaustive legal codes. Many verses lay out ethical guidelines and broad directives rather than specific procedural rules. This necessitates interpretation and elaboration through other sources, such as the Sunnah (prophetic traditions), consensus (ijma), and analogical reasoning (qiyas), to ensure that the principles of the Quran are effectively applied in diverse and changing contexts.
2. Hadith (or Sunnah)
The Hadith refers to the sayings, actions, and approvals of the Prophet Muhammad and serves as the second most important source of Muslim law after the Quran. While the Quran lays down broad principles, the Sunnah—derived from the Hadith—demonstrates their practical application. For example:
-
The Quran instructs Muslims to observe prayer (Salah), but the specifics regarding its method, timing, and structure are provided through the Hadith.
- In Sunni Islam, six primary Hadith collections are considered authentic, among which are Sahih al-Bukhari, Sahih Muslim, and Sunan Abu Dawood.In Shia Islam, compilations such as Al-Kafi are considered authoritative.
To be accepted as a valid source of law, a Hadith must meet certain criteria:
-
It must be authentic (Sahih).
-
It should have a reliable and unbroken chain of narrators (Isnad).
-
It must not contradict the Quran in content or principle.
3. Ijma (Consensus of Scholars)
Ijma refers to the unanimous consensus of qualified Islamic jurists on a legal issue after the death of Prophet Muhammad. Although technically a secondary source, it is often treated with the authority of a primary source due to its vital role in the development and continuity of Islamic jurisprudence.
A well-known example of Ijma in practice is the compilation of the Quran into a single, standardized text during the caliphate of Uthman ibn Affan—an action not undertaken during the Prophet’s lifetime but accepted unanimously by the companions.
Ijma can take two forms:
-
Explicit (Sarih) – A clear and unchallenged agreement among jurists.
-
Tacit (Sukuti) – Silent approval, where most jurists do not object to a prevailing opinion.
Ijma offers legal consistency and cohesion, particularly when dealing with new or unresolved issues that are not explicitly addressed in the Quran or Hadith.
4. Qiyas (Analogical Reasoning)
Qiyas refers to analogical reasoning—deriving a legal ruling for a new issue by identifying a common underlying cause (‘illah) with an existing ruling found in the Quran or Hadith.
Example:
The Quran prohibits the consumption of wine (khamr) because of its intoxicating effect. Using Qiyas, this ruling is extended to modern intoxicants like heroin or other narcotic drugs, as they share the same ‘illah (intoxication).
Qiyas is widely accepted by Sunni schools of law, including Hanafi, Shafi’i, Maliki, and Hanbali. However, Shia jurisprudence generally rejects Qiyas, preferring ‘Aql (independent reasoning) as a method of deriving legal rulings.
IV. Secondary Sources of Muslim Law
1. Istihsan (Juristic Preference)
Istihsan is a juristic principle that allows for exceptions to strict analogical reasoning (Qiyas) in favor of equity, fairness, and public interest. It enables scholars to choose a more just and practical ruling when rigid application of Qiyas may lead to hardship or an unjust outcome.
Example:
If applying Qiyas strictly results in undue difficulty or injustice, Istihsan permits a departure from that analogy to ensure a more compassionate and fair ruling.
The Hanafi school is especially known for its frequent and systematic use of Istihsan as a means to balance legal consistency with social justice.
2. Istislah or Maslahah (Public Interest)
Istislah is a legal principle that allows rulings to be made based on maslahah (public welfare or common good), especially in cases where the Quran, Hadith, Ijma, and Qiyas do not offer explicit guidance. It emphasises promoting benefits and preventing harm in society.
Example:
While classical sources may not mention building schools or hospitals, such actions are legally supported under Istislah due to their clear benefit to the community.
The Maliki school applies Istislah extensively, using it as a core method of legal reasoning. Other Sunni schools recognize its value but apply it more cautiously to ensure it does not conflict with established sources.
3. ‘Urf (Custom and Usage)
‘Urf refers to customary practices or local traditions that are accepted as a source of law, as long as they do not conflict with the Quran or Hadith. It acknowledges the importance of societal norms in shaping the application of Islamic law.
Example:
In marriage contracts, the mahr (dowry) amount is often determined based on local customs rather than a fixed scriptural standard, reflecting the role of ‘Urf in personal law.
‘Urf is especially significant in matters like marriage ceremonies, inheritance practices, and commercial dealings, allowing Islamic law to adapt to cultural and regional variations.
4. Fatwa (Legal Opinion)
A Fatwa is a non-binding legal opinion issued by a qualified Islamic jurist (Mufti) in response to a specific legal or ethical question. Although not a formal source of law, a Fatwa serves as an important interpretive tool that helps apply Islamic principles to contemporary issues.
Example:
Fatwas have addressed modern concerns such as organ donation, in vitro fertilization (IVF), and the permissibility of cryptocurrencies—topics not explicitly covered in classical texts.
In modern times, Fatwas play a crucial role in bridging traditional Islamic law with emerging societal and technological challenges, providing guidance where established jurisprudence may be silent.
5. Legislation and Judicial Decisions in Muslim Countries
In countries like India, Muslim law is also shaped by judicial decisions and statutory interventions. Some examples include:
- The Muslim Personal Law (Shariat) Application Act, 1937: This Act affirmed that Shariat (Islamic law) would serve as the governing law for Muslims in personal matters such as marriage, divorce, inheritance, and family relations, replacing customary practices that were previously followed.
- It marked a significant move towards codifying Islamic principles in personal matters, ensuring uniformity within the Muslim community. The Act empowered courts to decide disputes among Muslims based on Islamic jurisprudence rather than local or tribal customs.
- The Muslim Women (Protection of Rights on Divorce) Act, 1986: Passed in the aftermath of the Shah Bano case, this law altered the legal framework for maintenance of divorced Muslim women, limiting a husband’s liability to the iddat period, while placing responsibility for further support on relatives or the Waqf Board. The Act was seen as a political compromise between upholding Muslim personal law and addressing women’s rights. It sparked nationwide debate on secularism, gender justice, and the need for a Uniform Civil Code.
Indian courts frequently interpret and apply Muslim law principles, contributing to its modern development.
V. Schools of Islamic Jurisprudence and Their Influence
Muslim law varies across sects and regions due to different interpretations of these sources. The major Sunni schools include:
-
Hanafi – Known for its rationalist approach, the Hanafi school permits broad use of Qiyas (analogy) and Istihsan (juristic preference), allowing flexibility in interpretation. It is the most widely practiced school of thought in South Asia and certain regions of the Middle East.
-
Shafi’i – Emphasizing strict adherence to textual sources, especially Hadith, the Shafi’i school developed a structured legal methodology.It is practiced in Southeast Asia, East Africa, and various parts of the Middle East.
-
Maliki – This school places importance on the practices of the people of Medina and incorporates ‘Urf (custom) and Istislah (public interest) into its legal framework.
-
Hanbali – The most conservative Sunni school, Hanbali law relies strictly on the Quran and authentic Hadith, minimizing use of Qiyas or Istihsan. It underpins the legal system of Saudi Arabia.
In Shia Islam, the Ja’fari school relies more on reasoning (‘Aql) and the sayings of the Imams (considered infallible), rejecting Qiyas and preferring personal interpretation (Ijtihad).
VI. Application in India: A Pluralistic Legal Landscape
In India, Muslim law operates as a form of personal law, governing Muslims in areas such as marriage, divorce, guardianship, and inheritance. Courts refer to Quranic injunctions, classical texts (like Hidayah or Fatawa-i-Alamgiri), and authoritative commentaries.
Over time, judicial interpretations have modernized some aspects—for instance:
-
Triple talaq was ruled unconstitutional by the Supreme Court in Shayara Bano v. Union of India (2017)..
-
Courts have upheld that maintenance under Section 125 of the CrPC applies universally, irrespective of an individual’s religion.
Thus, while the core sources remain divine and classical, the application of Muslim law in India is subject to constitutional scrutiny, statutory reforms, and judicial activism.
VII. Contemporary Relevance and Challenges
Muslim law faces the challenge of balancing tradition with modernity, striving to uphold timeless religious principles while addressing contemporary social, legal, and technological developments. Issues like gender equality, uniform civil code debates, and digital age dilemmas demand reinterpretation of sources.
Efforts by scholars and reformist movements are underway to:
-
Revisit Hadith authenticity in light of modern values
-
Encourage Ijtihad (independent reasoning)
-
Promote gender-sensitive interpretations of Quranic law
While the primary sources remain sacrosanct, their interpretation must evolve to align with contemporary human rights standards, social justice, and constitutional values.
Conclusion
Muslim law is a dynamic amalgamation of divine revelation and human interpretation. Rooted in the Quran and Sunnah, and shaped by tools like Ijma and Qiyas, it balances timeless values with evolving reasoning. Its strength lies in the depth and flexibility of its sources—from the eternal word of God to centuries of juristic scholarship. This diversity has enabled it to remain relevant across different historical and social contexts.
In India, these sources are integrated into a pluralistic legal framework that accommodates both religious personal laws and secular statutes. Muslim law not only enriches the country’s legal diversity but also sparks vital constitutional debates on issues like gender justice, secularism, and personal freedoms. Understanding these sources is crucial for anyone engaging with the intersection of faith, law, and modern democratic society.
