Al-Muttafiq wal-Muftariq (The Homonymous and Distinct) is a hadith biographical reference work by the Baghdadi scholar and historian al-Khatib al-Baghdadi (392–463 AH / 1002–1071 CE), devoted to resolving ambiguities among hadith narrators who share identical names, patronymics, or lineages but are separate individuals.
Purpose and Scope
In hadith terminology, al-muttafiq wal-muftariq denotes names, patronymics, titles, lineages, or kunyas that are identical in both written form and vocalization while referring to entirely distinct persons—comparable to homonyms (al-mushtarak) in legal theory. Al-Khatib notes in his introduction that this subject represents a subtle discipline within hadith criticism where prominent scholars have frequently erred by conflating different individuals into one, especially when they were contemporaries sharing teachers or students. Distinguishing between them prevents attributing the narrations or status of an unreliable narrator to a trustworthy one, or vice versa. Al-Khatib read the book out loud to students at the Grand Mosque in Damascus in Ramadan 458 AH.
Structure and Method
According to Abu Sa'd al-Sam'ani, the work was compiled in eighteen parts (ajza'), while other transmission descriptions count sixteen parts. Al-Khatib groups narrators under homonymous headwords according to various configurations of agreement, including:
- Those whose given names and fathers' names are identical (such as multiple figures named al-Khalil ibn Ahmad).
- Those whose names, fathers' names, and grandfathers' names match (such as four contemporary narrators named Ahmad ibn Ja'far ibn Hamdan).
- Those whose names, fathers' names, and tribal or regional affiliations (nisbas) or kunyas coincide.
For each homonymous figure, al-Khatib provides distinguishing biographical markers, including their specific teachers, students, geographical origins, death dates, and assessments of reliability (al-jarh wal-ta'dil), supporting the entries by quoting hadiths with full chains of transmission (asānīd).
Reception and Scholarly Impact
Later hadith authorities praised al-Muttafiq wal-Muftariq as an invaluable and comprehensive cornerstone in its field. However, Ibn al-Salah remarked that despite its substantial size and breadth, the book did not exhaust all conceivable subdivisions of the discipline or account for every known bearer of certain names, noting that al-Khatib omitted four out of the six individuals named al-Khalil ibn Ahmad.
Abridgments and Editions
Owing to the book's extensive inclusion of full hadith chains, several scholars prepared abridgments to make the biographical data more accessible:
- Abu al-Qasim Ibn al-Farra' (d. 580 AH) produced Tajrīd al-Asmāʾ wal-Kunā al-Madhkūrah fī Kitāb al-Muttafiq wal-Muftariq, in which he stripped out the full chains of transmission, preserved the teachers, students, critical verdicts, and death dates recorded by al-Khatib, and added supplementary biographical material largely taken from al-Bukhari's al-Tārīkh al-Kabīr.
- Ibn Hajar al-Asqalani commenced an abridgment and critical supplement to the work, drafting a small portion before leaving it incomplete; it was subsequently continued and completed by al-Sakhawi.
The text has been edited and published in print under the editorship of Muhammad Sadiq al-Hamidi (Aydin).
