In a time when laws evolve at the speed of politics, Islam stands out by rooting its legal framework in revelation. Yet, the Qur’an alone does not represent the full legislative vision of Islam. The Prophet Muhammad (PBUH), through his words, actions, and approvals, became the living embodiment of the Qur’an, transforming divine instruction into practical guidance. This lived example is what Muslims refer to as Sunnah.
Without the Sunnah, the Qur’an would remain a divine constitution, comprehensive yet abstract in certain places. The Sunnah serves as its operational manual, bringing clarity to ambiguity, details to general commands, and enforcement to ideals.

Qur’anic Foundation for Following the Sunnah
Far from being optional, the Sunnah is a Qur’anic obligation. The Qur’an consistently commands believers to obey the Prophet. As the Quran says, “And whatever the Messenger has given you—take it; and what he has forbidden you—refrain from it.” (Surah Al-Hashr, 59:7). Moreover, Allah says, “He who obeys the Messenger has indeed obeyed Allah.” (Surah An-Nisa, 4:80)
These verses eliminate the false dichotomy between the Qur’an and the Sunnah. The Messenger is not merely a conveyor of revelation, he is its chief interpreter, divinely guided and entrusted to demonstrate the Qur’an’s application.
Three Core Legislative Roles of the Sunnah
- Clarification of the Qur’an
The Qur’an, though complete in principles, often speaks in general terms. The Sunnah provides a practical explanation. The Qur’an commands prayer but does not explain how to perform it.
The Sunnah provides the method, timing, and structure of prayer, backed by thousands of authentic Hadiths. Likewise, the Qur’an obligates Zakaat but leaves its rates and details to be clarified through the Sunnah. Without the prophetic model, these obligations would be impossible to implement accurately.
- Independent Legislation
The Sunnah also serves as an independent source of law where the Qur’an is silent. For example, the prohibition of eating animals with fangs or birds with talons is not found in the Qur’an but is established by authentic Hadith (Sahih Muslim).
The inheritance rights of a grandmother, or the prohibition of combining certain relatives in marriage, also derive directly from the Sunnah. The Prophet (PBUH) was not innovating but legislating by divine instruction beyond the literal text of the Qur’an.
- Abrogation or Specification
While rare, some Hadiths specify or even limit the application of certain Qur’anic verses. Scholars of Usul al-Fiqh accept that the Sunnah can explain or refine the context of Qur’anic rulings.
For example, the Qur’an allows punishment for theft, but the Sunnah sets the threshold of stolen value and outlines exceptions (e.g., in times of famine). This ensures that Islamic law remains rooted in divine justice, not rigid literalism.
The Sunnah as a Legal Institution
Beyond spiritual guidance, the Sunnah served as the first judiciary and legislative authority in Islam. The Prophet (PBUH) resolved disputes, implemented penalties, and judged between individuals using both revelation and personal discretion (ijtihad) guided by divine protection.
His companions, when becoming judges or governors, based their decisions on three layers:
- Qur’an
- Sunnah
- Personal reasoning (Ijtihad) if the first two were silent
A famous incident during the Prophet’s lifetime illustrates this process. When Mu’adh ibn Jabal was sent to Yemen as a governor, the Prophet asked him how he would judge. Mu’adh replied:
By the Book of Allah.
And if you find nothing therein?
Then by the Sunnah of the Messenger of Allah.
And if you find nothing therein?
Then I will use my own reasoning to form an opinion.
The Prophet (PBUH) approved his answer.
This shows how the Sunnah was always the second recourse after the Qur’an in matters of legislation.

Sunnah in the Modern Legal Framework
Many modern Muslim-majority states today wrestle with the question: Should Sunnah still influence legislation? For scholars and jurists of classical and contemporary Islam, the answer remains yes.
The Ottoman Empire’s “Majallah” (civil code), Pakistan’s Hudood Ordinances, and the Egyptian personal status laws all contain provisions derived directly from the Sunnah.
Moreover, areas like:
- Contract law (e.g., prohibition of uncertainty - gharar)
- Banking and finance (e.g., prohibition of interest - riba)
- Family law (e.g., maintenance, divorce, custody)
- Criminal justice (e.g., standards for evidence, repentance before punishment)
All rely heavily on the Sunnah for both ethical guidance and legal clarity. In fact, modern fiqh councils, such as the International Islamic Fiqh Academy, continue to base rulings on the Qur’an and Sunnah, proving the Sunnah’s continued relevance.
Countering Misconceptions
Some modernist critics argue that reliance on the Sunnah opens the door to outdated laws or rigid traditionalism. But this stems from a misunderstanding. The Sunnah is not a collection of cultural habits but a divinely endorsed model of ethical and legal reasoning.
What matters is not just what the Prophet did, but why he did it; the rationale, intent, and moral framework. Islamic scholars throughout history have differentiated between:
- Descriptive Sunnah (personal habits like sleeping posture or favorite foods)
- Prescriptive Sunnah (legal and moral instructions with lasting applicability)
Understanding this distinction allows us to apply the Sunnah wisely in a modern context, preserving its core objectives (maqasid al-shariah) while adapting to new realities.
The Sunnah Is the Heartbeat of Islamic Law
The Qur’an is the foundation of Islamic life, but the Sunnah is its living spirit. It transforms divine law into human action. It clarifies, legislates, and explains in a way that no legal text alone can.
To disconnect Islamic legislation from the Sunnah is to leave the Qur’an incomplete in practice. The Prophet Muhammad (PBUH) was not only a messenger but also the first legislator, the first judge, and the first practitioner of Islamic law.
In a world searching for ethical clarity, the Sunnah offers not just ritual continuity but moral depth, legal sophistication, and societal balance. It is not just a relic of history—it is a framework for justice, mercy, and reason.
