The Sources of Islamic Law (Usul al-Fiqh)
Usul al-fiqh (أُصُولُ الفِقه — the roots/principles of jurisprudence) is the science of how legal rulings are derived from the sources. The four main sources, in order of authority:
1. Al-Quran al-Karim: The primary source — Allah’s direct speech. Every other source is subordinate to it. When the Quran speaks clearly on a matter, the ruling is established beyond dispute.
2. Al-Sunnah (the Prophetic practice): The Prophet’s (SAW) words, actions, and approvals as recorded in authenticated hadith. The Sunnah explains, specifies, and supplements the Quran — it is the living implementation of Quranic guidance. See [[hadith-sciences]] for how hadith is verified.
3. Ijma’ (إِجمَاع — scholarly consensus): When the scholars of a generation reach unanimous agreement on a ruling, that consensus is binding. The Prophet (SAW) said: “My community will never unanimously agree on an error.” (Abu Dawud) Ijma’ is powerful but rare — genuine unanimous consensus of all qualified scholars across the Islamic world.
4. Qiyas (قِيَاس — analogical reasoning): When a new situation arises not directly addressed by Quran, Sunnah, or ijma’, scholars find an analogous case from the sources and apply the same ruling to the new case, based on a shared underlying reason (‘illa). Example: wine is forbidden because of its intoxication; therefore all intoxicating substances share the same prohibition via qiyas.
Additional secondary sources (accepted by some schools and not others):
- Maslaha mursala (public interest): Rulings based on the general welfare of the Muslim community
- ‘Urf (custom): Local custom can influence rulings in areas not addressed by primary sources
- Istihsan (juristic preference): Departing from strict qiyas in favor of a ruling that better serves justice
- Sadd al-dhara’i’ (blocking means): Prohibiting an action that is technically permitted but regularly leads to harm
The Five Categories of Actions in Islamic Law
Every human action falls into one of five categories (al-ahkam al-khamsa):
1. Fard/Wajib (فَرض/وَاجِب — obligatory): Must be done. Omitting it is a sin. The five daily prayers, zakat, Hajj, fasting, etc.
2. Mandub/Mustahabb/Sunnah (مَندُوب/مُستَحَبّ/سُنَّة — recommended): Doing it is rewarded; omitting it is not punished. Voluntary prayers, optional fasts, using miswak, etc.
3. Mubah (مُبَاح — permitted/neutral): Doing or not doing carries no religious weight. Most ordinary daily activities: eating, sleeping, commerce, recreation (within limits).
4. Makruh (مَكرُوه — disliked): Discouraged but not forbidden. Doing it is not sinful but discouraged. Omitting it is rewarded. Eating onions before congregational prayer, wearing silk for men in most schools.
5. Haram (حَرَام — forbidden): Must not be done. Doing it is a sin requiring tawba. Alcohol, pork, riba, adultery, murder, etc.
This five-part classification applies to every question of fiqh — the scholar’s task is to determine which category any given act falls into.
The Four Sunni Madhabs
The Hanafi School (أَبُو حَنِيفَة — Abu Hanifa, 699-767 CE): The most widely followed school globally — dominant in Central Asia, South Asia (Pakistan, India, Bangladesh, Afghanistan), Turkey, the Levant, and Egypt. Known for: extensive use of ra’y (scholarly opinion) and istihsan (juristic preference), particularly when strict textual application would produce harsh results. Abu Hanifa was a merchant’s son who applied commercial common sense to legal questions.
The Maliki School (مَالِك ابن أَنَس — Malik ibn Anas, 711-795 CE): Dominant in West Africa, North Africa (Morocco, Tunisia, Algeria), Mauritania, and parts of the Gulf. Distinctive feature: the practice of the people of Medina (‘amal ahl al-Madina) is treated as a form of living Sunnah — Malik argued that the practice of the Prophet’s (SAW) city, preserved across generations, is itself a form of transmitted knowledge.
The Shafi’i School (مُحَمَّد ابن إِدرِيس الشَّافِعِي — al-Shafi’i, 767-820 CE): Dominant in East Africa, Egypt (alongside Maliki), Southeast Asia (Indonesia, Malaysia, Brunei), and parts of South Asia and the Gulf. al-Shafi’i is considered the founder of usul al-fiqh as a formal science — his Risala established the systematic methodology of Islamic jurisprudence. He codified the four-source hierarchy. The Dawoodi Bohras follow the Shafi’i school.
The Hanbali School (أَحمَد ابن حَنبَل — Ahmad ibn Hanbal, 780-855 CE): Dominant in Saudi Arabia and Qatar. Known for its strict adherence to textual sources (Quran and Sunnah) and minimizing speculative reasoning. Ibn Hanbal endured imprisonment and torture rather than accept the Mu’tazilite doctrine of the created Quran — his steadfastness became legendary. The Wahhabi/Salafi movement grew from the Hanbali tradition.
Ijtihad: Independent Legal Reasoning
Ijtihad (اِجتِهَاد — maximum effort; independent legal reasoning) is the process by which a qualified scholar (mujtahid) exercises independent reasoning on a legal question not definitively resolved by existing sources.
Requirements for ijtihad: Mastery of the Arabic language; mastery of the Quran and its sciences; mastery of hadith and its sciences; knowledge of ijma’; knowledge of the legal principles of usul al-fiqh; knowledge of the objectives of Islamic law (maqasid al-shari’a).
Taqlid (تَقلِيد — following): For those who are not mujtahids (the overwhelming majority of Muslims), taqlid — following an established madhab — is the required approach. Taqlid is not blind obedience but the rational recognition that one lacks the tools to derive rulings directly from sources, and therefore follows qualified scholars.
Contemporary ijtihad: Major modern questions that require ijtihad include: organ transplantation, cryptocurrency, surrogate pregnancy, artificial intelligence, biotechnology, interest in modern financial systems. Contemporary scholars engage these through the fiqh academies of the OIC and other scholarly bodies, applying the classical methodology to new questions.
Fiqh in the Bohra Tradition
The Dawoodi Bohra community follows the Shafi’i school for most external legal matters (zahir). Bohra fiqh combines:
- Shafi’i fiqh for the zahir (external legal practice)
- Ismaili fiqh for communal and religious matters governed by the da’wa
- The Da’i’s guidance as the binding authority for the community’s practice
The Da’i al-Mutlaq’s authority in Bohra tradition extends to both the external practice (following Shafi’i fiqh) and the esoteric ta’wil dimensions — his guidance is the living fiqh of the community, superseding historical scholarly positions on matters within his authority.
