(1) Commonly referred to as Ibn al-Salah’s Introduction (Muqaddimat Ibn al-Salah); its actual title is Maʿrifat ʿUlum al-Hadith (“Knowledge of the Hadith Sciences”). This is how the author names it in Siyanat Sahih Muslim, p. 75, and again on p. 6 where he calls it Maʿrifat Anwaʿ ʿIlm al-Hadith (“Knowledge of the Types of Hadith Science”). (2) Copy Ṭ reads al-wasf (“description”) instead of al-wadʿ (“fabrication”). (3) Copies Ṭ and Y read al-munasib (“appropriate”). (4) Copy K and the margin of J have al-mutafarriqa (“scattered”). (5) Copy Ṭ has ashtat (“various pieces”) in place of shatat (“dispersed matter”). (6) Copies B and Ṭ read faraʾiduha (“its rarities”) instead of fawaʾidiha (“its benefits”). (7) Copy Ṭ adds the preposition min (“of”). (8) Copy W vocalises the word as nazimun, nominative with tanwin; we adopt the unvowelled reading of A, D, and Z. (9) Copy W likewise has wa-mustadrakun, nominative with tanwin; we follow D and Z. (10) Ikhtisar (abridgment) means conveying the entire intended sense in fewer words than the original, whereas iqtisar (omission) means conveying only part of the intended sense. See Sharh Sharh al-Nukhba, p. 147. (11) Copy W reads wa-muʿaridun with nominative tanwin; we follow D. Al-Laqani states in Qadaʾ al-Watar, p. 416: “(nazim): everything that follows it is in the genitive because it is annexed to kam, some by direct annexation and some by syntactic subordination.” (12) Among those who versified the work are the hadith master al-ʿIraqi in al-Tabsira wa-l-Tadhkira; among those who abridged it are al-Nawawi and Ibn Kathir; among those who produced supplements to it is al-Bulqini in Mahasin al-Isitlah; and among its defenders are al-Zarkashi, al-ʿIraqi, and Ibn Hajar in his works entitled al-Nukat.
