(1) Al-Walid ibn Abda, the client (mawla) of ʿAmr ibn al-ʿAs. Abu Hatim judged him “unknown,” whereas Ibn Hibban lists him among the reliable transmitters. Because the sources differ greatly over his name, al-Bayhaqi expresses some doubt about it here. He died in 100 AH/718-19 CE. See: Tahdhib al-Tahdhib 11:141, no. 235; al-Jarh wa-l-Taʿdil 9:11, no. 49. (2) Manuscript B reads “ibn ʿUmar,” but the correct reading is “ibn ʿAmr.” See Sunan al-Bayhaqi 9:234. (3) Al-Bayhaqi records this report in his Sunan (9:234) through several isnads from ʿAbd Allah ibn ʿAmr; the author will cite them below. (4) Saʿid ibn al-Hakam ibn Muhammad ibn Salim, known as Ibn Abi Maryam al-Jumahi al-Misri, Abu Muhammad. The major critics rate him reliable, and the Six Books transmit from him. Born 144 AH/761-62 CE; died 224 AH/838-39 CE. See: Tahdhib al-Tahdhib 4:17-18, no. 23. (5) Manuscripts C and D read: haddathana (“he narrated to us”). (6) Nafiʿ ibn Yazid al-Kalaʿi al-Misri, Abu Yazid, said to have been the client of Shurahbil ibn Hasana. Muslim and others narrate from him. Ibn Hajar in Taqrib al-Tahdhib describes him as “trustworthy, devout, seventh generation.” Died 168 AH/784-85 CE. See: Taqrib al-Tahdhib 2:296, no. 28. (7) Sulaiman ibn Abi Zaynab al-Shami, so in al-Jarh wa-l-Taʿdil, whose margin adds the nisba “al-Sabayi.” All extant manuscripts, however, read “Salman,” which is probably a scribal error. See: al-Jarh wa-l-Taʿdil 4:118, no. 512. (8) ʿAmr ibn al-Harith ibn Yaʿqub ibn ʿAbd Allah al-Ansari, the client of Qays, al-Misri, Abu Umayya. The leading critics deem him reliable, and the Six Books transmit his hadiths. Born 90 AH/708-09 CE; died 147 AH/764-65 CE. He was the foremost scholar, hadith authority, and mufti of Egypt in his day. See: Tahdhib al-Tahdhib 8:14-16, no. 22.
