(1) Manuscript B reads simply: “Saʿid ibn Salama,” whereas manuscript A has: “He heard Saʿid, his father ibn Salama, who heard his father, who heard ʿUmar …,” a wording that is probably the result of a copyist’s confusion. (2) Saʿid ibn Salama ibn Abi al-Hisam, the client of the family of ʿUmar ibn al-Khattab, al-Madani, Abu ʿAmr al-Sadusi. Ibn Hajar (Taqrib al-tahdhib) describes him as “truthful; his written transmission is sound, but he errs when narrating from memory.” He belongs to the seventh generation of narrators, and Muslim, Abu Dawud, al-Nasaʾi, and al-Bukhari in al-Adab al-mufrad all transmit from him. See: Taqrib al-tahdhib 1:297, no. 184; Tahdhib al-tahdhib 4:41–42, no. 66. (3) Al-Bayhaqi, al-Sunan al-kubra, 9:234; al-Muttaqi al-Hindi, Kanz al-ʿummal, 1:405, no. 1732. (4) Manuscript A adds here: “Keep away from the enemies of Allah on their festivals,” and the phrase is repeated. I consider this duplication a scribal error. The wording is also reported with a sound chain from Abu Usama. Abu Usama is Hammad ibn Usama ibn Zayd al-Qurashi, their client, al-Kufi, a precise and trustworthy hadith scholar of the ninth generation; he died in 201 AH at the age of eighty. See: Taqrib al-tahdhib 1:195, no. 529; Tahdhib al-tahdhib 3:2–3, no. 1. (5) Manuscript A reads: “al-ʿajam (the non-Arabs).” (6) Al-Bayhaqi, al-Sunan al-kubra, 9:234. (7) Muhammad ibn Ibrahim ibn Abi ʿAdi—sometimes identified by his grandfather’s name—Abu ʿAmr al-Basri. Ibn Hajar judges him “trustworthy, ninth generation.” He died in 194 AH, and all Six Books transmit his hadiths. See: Taqrib al-tahdhib 2:141, no. 11.
