(1) Manuscript A adds the word “dhalika” (that). (2) The scholar in question is Abu Ahmad al-Hasan b. Abd Allah b. Sa id al- Askari (d. 382 AH); see Siyar A lam al-Nubala 16/413. His book is entitled Tas hifat al-Muhaddithin (Misreadings of the Hadith Scholars) and is in print. (3) Al-Daraqutni, Abu l-Abbas al-Dani, Ibn Nuqta, Abu Zur a al-Iraqi, and the present author all cite the work simply as al-Tas hif (Misreading); see: al-Mu talif wa-l-Mukhtalif by al-Daraqutni 4/2303; al-Ima by al-Dani 3/62; Ikmal al-Ikmal by Ibn Nuqta 2/538; al-Mustafad min Mubhamat al-Matn wa-l-Isnad by Abu Zur a al-Iraqi 1/453; and Talkhis al-Habir by Ibn Hajar 4/1857. Al-Mizzi calls it al-Tas hif wa Akhbar al-Musahifin (Misreadings and Reports about Those Who Misread) in Tahdhib al-Kamal 19/486; 25/107, while Ibn Khayr cites it as Tas hif al-Muhaddithin; see his Fahrasah, p. 256. (4) The words “wa ghayruhuma” (and others besides them) are absent from manuscript D. Al-Khattabi also authored a work on the subject, Islah Khata al-Muhaddithin (Correcting the Errors of the Hadith Scholars), now published. (5) The phrase “wa aktharu ma yaqa u fi l-mutun” (and most instances occur in the texts) is omitted in manuscript Z. (6) Manuscript D reads “taqaʿ” (occurs). Manuscript L has a lacuna here equal to one folio. (7) In the margin of manuscript H: “Then it was collated in reading and revision. Written by its author.”
