Risala fi Usul al-Fiqh (A Treatise on Legal Theory) is a concise Hanbali primer on legal theory (usul al-fiqh) attributed to Abu Ali al-Hasan ibn Shihab al-Ukbari (335–428 AH / 946–1037 CE) .
Structure and Content
The treatise opens with a classification of legal rulings into seven categories: the obligatory (wajib), permissible (mubah), prohibited (mahzur), recommended (mandub ilayh), sunna, valid (sahih), and invalid (fasid) . Within these definitions, it discusses lexical and legal nuances, affirming that obligation (fard) and duty (wajib) are synonymous according to the sound position transmitted from Ahmad ibn Hanbal .
The text organizes the foundational proofs of Islamic law into six primary sources across six dedicated sections:
- The Book of Allah: Covering ten interpretive modalities, including the specific (khass), general (amm), clear (muhkam), ambiguous (mutashabih), summary (mujmal), unqualified (mutlaq), qualified (muqayyad), and abrogation (naskh) .
- The Sunna: Incorporating the Prophet's verbal pronouncements, physical actions, and tacit approvals (iqrar) .
- Consensus (ijma'): Defined as the agreement of the scholars of a given era upon a legal case, substantiated as a binding authority .
- Analogy (qiyas): Exploring forms of legal reasoning, including juristic preference (istihsan) and the levels of determining effective legal causes: verifying the cause (tahqiq al-manat), refining the cause (tanqih al-manat), and extracting the cause (takhrij al-manat) .
- Presumption of Continuity (istishab al-hal) .
- The Opinion of a Single Companion (qawl al-sahabi al-wahid) .
The work also elaborates on divergent implication (dalil al-khitab or mafhum al-mukhalafa), definitions of responsibility (taklif), strict law (azima), and dispensations (rukhsa) . In its conclusion, the author refers readers seeking an exhaustive presentation of legal rulings, theoretical principles, divergent school doctrines, proofs, and rejoinders to his expansive work titled al-Mabsut .
Attribution and Scholarly Reception
In classical Hanbali literature, Ibn Muflih cited legal positions from Ibn Shihab in his Usul al-Fiqh, including transmissions concerning the position of the Companion and reports from al-Tamimi, which were subsequently cited by al-Mardawi in al-Tahbir . Modern scholars, including Bakr Abu Zayd and 'Abd Allah al-Turki, also attributed the text directly to Ibn Shihab al-Ukbari .
Some scholars expressed skepticism regarding its attribution, arguing that its terse, structured style resembles late didactic compendia rather than the works of earlier authorities, or suggesting that it might have belonged to another Hanbali scholar from Ukbara, such as Abd al-Jabbar ibn Abd al-Khaliq al-Ukbari . In defense of the attribution to Ibn Shihab, researchers pointed out that the work explicitly refers to the author's larger treatise al-Mabsut, a book not ascribed to Abd al-Jabbar in biographical records, and that its legal definitions align with early authorities such as al-Qadi Abu Ya'la .
Manuscripts and Editions
A preserved manuscript copy is registered under number 345 (4), spanning ten folios (ff. 63–72) transcribed in 1333 AH .
The text has been published in multiple modern editions:
- Edited by Muwaffaq ibn Abd Allah and published by al-Maktaba al-Makkiyya in Mecca in 1413 AH / 1993 CE .
- Edited with commentary by Badr ibn Nasir ibn Mishri' al-Subay'i, published jointly by Dar Lata'if and Dar Arwiqa in 1438 AH / 2017 CE .
