The following question was asked in CSS 2002. Islamic law, known as Shariah, is derived from divine and rational foundations that ensure justice, morality, and social harmony. Its four primary sources are the Qur’an, Sunnah, Ijma, and Qiyas. However, Islamic jurists have also recognized several supporting tools such as Masalih-e-Mursala (public interest), Istihsan (juristic preference), and ‘Urf (custom) to address new issues. These sources provide Islam with legal dynamism and the capacity to adapt to changing human conditions without compromising core values. This article explores the primary and secondary sources of Islamic law and their role in the development of Islamic legal theory.

Answer to the Question

Introduction

Islamic law, or Shariah, is a comprehensive legal and ethical code derived from divine revelation and rational interpretation. Its foundation rests on four primary sources, supplemented by secondary principles to address new challenges in society. These sources ensure that Islamic jurisprudence remains both rooted in divine guidance and responsive to changing circumstances. Jurists throughout Islamic history have employed tools such as Masalih-e-Mursala, Istihsan, and ‘Urf to uphold justice and serve public welfare without departing from the essence of Shariah.

The Four Basic Sources of Islamic Law

A. Qur’an

The Qur’an is the primary and most authoritative source of Islamic law. It contains direct commandments, legal injunctions, and moral principles governing all aspects of life. The Qur’an establishes the basic framework of belief, worship, transactions, and criminal law.
“We have sent down to you the Book as clarification for all things and as guidance and mercy and good tidings for the Muslims.”
(Surah An-Nahl 16:89)

B. Sunnah

The Sunnah consists of the sayings, actions, and approvals of the Prophet Muhammad (PBUH). It serves as a practical explanation of the Qur’anic injunctions and provides rulings on matters not explicitly covered in the Qur’an. Sunnah is considered the second source of Islamic law. “And whatever the Messenger has given you, take; and what he has forbidden you, refrain from.” (Surah Al-Hashr 59:7)

C. Ijma (Consensus)

Ijma refers to the consensus of qualified Islamic scholars on a legal issue after the time of the Prophet (PBUH). It reflects the collective reasoning of the Ummah and is used to resolve contemporary issues when there is no explicit text in the Qur’an or Sunnah. The legitimacy of Ijma is based on the Hadith stating that the Ummah will not agree upon an error.

D. Qiyas (Analogy)

Qiyas is a form of analogical reasoning, where a new issue is resolved by comparing it with an existing ruling from the Qur’an or Sunnah based on a common underlying cause (‘illah). For instance, the prohibition of drugs is derived through Qiyas from the prohibition of alcohol due to their shared intoxicating effect.

Supplementary Sources of Islamic Law

A. Masalih-e-Mursala (Public Interest)

Maslahah refers to considerations based on public welfare, which are not explicitly stated in the texts but are in line with the objectives of Shariah (Maqasid al-Shariah). Jurists use this principle when a ruling is required to protect life, religion, intellect, lineage, or property, especially in the absence of specific evidence. Imam Malik is known for extensively using Masalih-e-Mursala in his legal rulings.

B. Istihsan (Juristic Preference)

Istihsan is the principle of preferring a stronger legal opinion over another based on context and public interest. It allows jurists to depart from strict analogy when it results in hardship or injustice. For example, in business contracts, certain rulings are preferred based on practicality and fairness, even if they diverge from general analogy. Imam Abu Hanifa extensively used this tool.

C. ‘Urf (Custom)

‘Urf refers to accepted cultural norms and practices of a society that do not contradict Islamic principles. Islam recognizes local customs in matters like trade, marriage, and social interactions, provided they align with Shariah. The Prophet (PBUH) said: “Whatever Muslims deem as good is good in the sight of Allah.” (Ahmad ibn Hanbal)

Significance of Primary and Secondary Sources in Islamic Jurisprudence

Together, these sources provide a balanced and dynamic framework for Islamic legal thought. The primary sources ensure that all rulings are rooted in revelation, while secondary tools enable scholars to address changing human conditions without compromising Shariah. The integration of revealed and rational methods ensures justice, ease, and continuity in Islamic law.

Critical Analysis

The beauty of Islamic law lies in its combination of divine authority and human reasoning. While the Qur’an and Sunnah provide unchangeable principles, tools like Maslahah, Istihsan, and ‘Urf ensure flexibility. This dual approach preserves the sacredness of the law while making it relevant to contemporary challenges. However, caution must be exercised to ensure that these tools are not misused to justify un-Islamic practices.

Conclusion

Islamic law is a complete and adaptable system derived from both divine revelation and juristic reasoning. The Qur’an, Sunnah, Ijma, and Qiyas form its foundational sources, while Masalih-e-Mursala, Istihsan, and ‘Urf serve as essential interpretive tools. Together, they uphold the objectives of Shariah and provide solutions that are just, practical, and spiritually grounded. Understanding and applying these sources is crucial for the revival of Islamic jurisprudence in the modern era.
