(1) The word “ibn” is absent from T. (2) He is al-Qadi Abu Ya‘la Muhammad ibn al-Husayn ibn Muhammad al-Baghdadi, known as Ibn al-Farra (d. 458/1066). See: Siyar A‘lam al-Nubala’, 18:89. (3) J reads “al-‘Abkari,” a scribal error; W and T have “al-Akburi,” with the ba vocalized with damma, and this is the reading adopted from H, Ḥ, and K. Al-Laqani states in Qada’ al-Watar, p. 1662: “with damma on the ‘ayn, sukun on the kaf, and fatha on the ba.” Al-Sam‘ani adds in al-Ansab, 9:345: “with damma on the ‘ayn and fatha on the ba—some say damma on the ba as well, but the correct pronunciation is with fatha.” Cf. Yaqut, Mu‘jam al-Buldan, 4:142; the author’s Tabsir al-Muntabih bi-Tahrir al-Mushtabih, 3:1017. The author of Fath al-Bari, 11:86, notes that he never saw the original work of al-Akburi but only an abridgment: “Abu Hafs al-Akburi—one of the teachers of Abu Ya‘la Ibn al-Farra—devoted a monograph to the causes of hadith transmission in the fifth century; I have seen only an abridgment of it.” I have not been able to determine which al-Akburi this refers to. (4) See Ihkam al-Ahkam, 1:62. (5) J again has “al-‘Abkari,” a misreading; W and T read “al-Akburi” with damma on the ba, which is the form adopted from D, H, and K. (6) D vocalizes “al-madhkur” in the nominative, L in the genitive; the other copies omit it. The accusative is preferable, as it functions as an adjective for the construct noun tasnif; nominative or genitive is unlikely here. (7) B alone adds the preposition “min.” (8) The demonstrative “hadhihi” (this) is missing in K.
