al-Asl li Muhammad ibn al-Hasan

Al-Asl (also known as al-Mabsut) is a foundational treatise of Hanafi jurisprudence composed by Muhammad ibn al-Hasan al-Shaybani (d. 189 AH / 805 CE) al-Asl li Muhammad ibn al…+1. It is the primary and most extensive work among the six zahir al-riwayah ("authoritative transmission") texts that systematically preserve the legal doctrines of Abu Hanifah, Abu Yusuf, and al-Shaybani al-Tashih wa al-Tarjih al…+1.

Title and Composition

The book is traditionally known by two titles: al-Asl ("the Root" or "the Foundation") and al-Mabsut ("the Expounded") al-Asl li Muhammad ibn al…+1. It was designated al-Asl because al-Shaybani composed it first, prior to his other legal works, making it the foundational source for subsequent Hanafi literature al-Asl li Muhammad ibn al…+1.

Al-Shaybani originally authored the work as individual, specialized treatises devoted to specific subjects of substantive law (furu'), such as the book of prayer (Kitab al-Salat), sales (Kitab al-Buyu'), oaths (Kitab al-Ayman), coercion (Kitab al-Ikrah), and menstruation (Kitab al-Hayd) Kashf al-Zunun an Asami a…+1. These separate treatises were subsequently gathered into a unified corpus, likely by his students and transmitters, as early bibliographers such as Ibn al-Nadim continued to record them as distinct entries rather than under a single unified title al-Asl li Muhammad ibn al…+1. In manuscript form, the work spans roughly 2,260 folios and was typically arranged into four to six large volumes al-Asl li Muhammad ibn al…+1.

Content and Methodology

The work covers tens of thousands of legal rulings across the entire range of ritual worship and civil transactions al-Asl li Muhammad ibn al…+1. Al-Shaybani's method consists of enumerating substantive cases according to the doctrines of Abu Hanifah and Abu Yusuf, while articulating his own analytical positions and disagreements al-Asl li Muhammad ibn al…+1.

The text features two primary stylistic modes: a dialogical question-and-answer format ("I said / He said") and conditional hypothetical propositions ("if", "should") al-Asl li Muhammad ibn al…. With respect to textual proofs, al-Shaybani generally omits hadith citations when the supporting narrations were widely known among contemporary jurists, citing specific traditions (athar) and chains of transmission only for issues where the textual evidence might be less familiar; if compiled independently, these narrations would form a modest volume al-Asl li Muhammad ibn al…+1.

Transmission and Reception

The book was transmitted from al-Shaybani by several of his direct students, most prominently Abu Sulayman al-Juzjani—whose recension became the most widespread and well attested—as well as Muhammad ibn Sama'ah al-Tamimi and Abu Hafs al-Kabir al-Bukhari al-Asl li Muhammad ibn al…+1. It was taught and disseminated in major scholarly centers, including Baghdad, Bukhara, and Rayy, thereby facilitating the spread of Hanafi jurisprudence across these regions al-Asl li Muhammad ibn al….

Within the Hanafi school, al-Asl forms the highest tier of doctrinal authority (zahir al-riwayah and masa'il al-usul), and Hanafi jurists held that judges and muftis are bound to follow its transmitted positions over irregular reports (al-riwayah al-shadhdhah) al-Tashih wa al-Tarjih al…+1. Beyond the school, the work significantly influenced early legal codification across other traditions: al-Shafi'i reportedly memorized it and structured his Kitab al-Umm after its model; Asad ibn al-Furat authored al-Asadiyyah (the foundational source of Sahnun's al-Mudawwanah in the Maliki school) under its influence; and Ahmad ibn Hanbal made use of al-Shaybani's works when answering intricate legal queries al-Madkhal ila Dirasat al…+1.

Commentaries, Abridgments, and Editions

Early Hanafi scholars composed commentaries on al-Asl, including Shams al-A'immah al-Halwani and Abu Bakr Muhammad ibn Abi Sahl (known as Khawahirzadah, author of Mabsut al-Bakri), who integrated their commentaries directly into the text Kashf al-Zunun an Asami a…+1. Al-Hakim al-Shahid (d. 334 AH) later condensed al-Asl alongside the other five zahir al-riwayah works into his comprehensive summary al-Kafi, which itself served as the basis for al-Sarakhsi's expansive thirty-volume commentary, also entitled al-Mabsut al-Tashih wa al-Tarjih al…+1. Muhammad ibn Ibrahim al-Hanafi also produced an abridgment titled Mukhtasar al-Asl al-Asl li Muhammad ibn al….

Manuscript copies of al-Asl are preserved in library collections across Istanbul (such as the Feyzullah, Carullah, Veliuddin, Kara Mustafa Pasha, and Murad Molla libraries) and Cairo (including al-Azhar and Dar al-Kutub) al-Asl li Muhammad ibn al…+1. Portions of the work were published in Hyderabad under the editorship of Abu al-Wafa al-Afghani, as well as by Majid Khadduri, before modern scholars completed full critical editions based on surviving manuscripts al-Asl li Muhammad ibn al…+1.
