# Major schools of Islamic thought & jurisprudence

The four Sunni madhahib, principal Shia jurisprudence, the sources and methods of usul al-fiqh, and Pakistan's constitutional accommodation of sectarian diversity.

## The architecture of Islamic jurisprudence

Islamic law (*fiqh*) is the jurist's human understanding of the divine law (*Shariah*). Its discipline of legal theory, *usul al-fiqh*, was systematised above all by Imam Muhammad ibn Idris al-Shafi'i (d. 820 CE) in his treatise *al-Risala*, which fixed the four agreed sources for Sunni Islam in descending authority:

1. **The Qur'an** — the primary, uncreated source.
2. **The Sunnah** — the normative practice of the Prophet Muhammad (d. 632 CE), transmitted as Hadith and graded by the science of *isnad* (chain of narration).
3. **Ijma** (consensus) — the agreement of qualified scholars of a generation, grounded in the Prophetic report 'My community will not agree upon an error.'
4. **Qiyas** (analogical reasoning) — extending a ruling from a textual case to a new case sharing the same effective cause (*illa*).

Beyond these four, schools deploy subsidiary instruments: *istihsan* (juristic preference, prominent in the Hanafi school), *istislah* / *maslaha mursala* (consideration of public interest, developed by the Maliki Imam al-Shatibi in *al-Muwafaqat*), *urf* (custom), and *istishab* (presumption of continuity).

## Ijtihad and taqlid

The engine of legal development is *ijtihad* — the exertion of a qualified jurist (*mujtahid*) to derive rulings from the sources. Its counterpart is *taqlid*, the adherence of a lay follower (*muqallid*) to an established school. The medieval claim that 'the gate of ijtihad closed' after roughly the 4th Islamic century is now contested by historians such as Wael Hallaq, who demonstrated continuous juristic activity. Modern reformers — Jamal al-Din al-Afghani (d. 1897), Muhammad Abduh (d. 1905), and in the subcontinent Sir Sayyid Ahmad Khan (d. 1898) and Muhammad Iqbal — called for the reopening of ijtihad; Iqbal devoted the sixth lecture of *The Reconstruction of Religious Thought in Islam* (1930) to 'The Principle of Movement in the Structure of Islam,' arguing that a Muslim legislative assembly could exercise collective ijtihad.

## The five categories of acts

All Sunni schools classify human acts into five legal values (*al-ahkam al-khamsa*): *wajib/fard* (obligatory), *mandub/mustahabb* (recommended), *mubah* (permissible), *makruh* (disliked), and *haram* (forbidden). The higher objectives of the law — the *maqasid al-shariah* — were articulated by al-Ghazali (d. 1111) and al-Shatibi as the preservation of religion (*din*), life (*nafs*), intellect (*aql*), lineage (*nasl*), and property (*mal*). This framework underpins contemporary debates on Islamic finance, bioethics, and constitutional law, and is a recurring high-yield theme for the CSS Islamic Studies paper.
