(1) See Sunan Abi Dawud, Book of Etiquette, chapter “Tribal Partisanship,” hadith no. 5120 (5:341). The isnad contains Ayyub ibn Suwayd; Abu Dawud comments, “Ayyub ibn Suwayd is weak.” Ayyub ibn Suwayd al-Ramli al-Saybani, known as Abu Masud, was judged unreliable by Ahmad, Ibn Main, al-Bukhari, Abu Hatim, al-Nasaʾi and the other hadith critics. He died in 202 AH. Cf. Ibn Hajar, Tahdhib al-Tahdhib 1:405–406, no. 745. (2) The printed edition reads: “Abu Dawud.” (3) In MS J the word appears as muʿazzam; this is an error. (4) The Companion Jubayr ibn Mutim ibn ʿAdi ibn Nawfal al-Qurashi was one of Quraysh’s sagacious nobles and a noted genealogist whose expertise was sought for both Quraysh and the wider Arabs. His father al-Mutim had granted the Prophet safe-conduct on his return from Taif and had helped annul the iniquitous boycott of the Muslims, Banu Hashim and Banu al-Muttalib. Jubayr accepted Islam before the Conquest of Mecca. On the eve of the Conquest the Prophet said, “In Mecca there are four men of Quraysh whose nobility shields them from polytheism and whom I long to see embrace Islam,” and he named Jubayr among them. He died in 57 AH. See Ibn al-Athir, Usd al-Ghabah 1:271–72. (5) Sunan Abi Dawud, Book of Etiquette, chapter “Tribal Partisanship,” hadith no. 5121 (5:342). Muslim relates the same purport in Kitab al-Imarah, hadith no. 1848, from Abu Hurayrah. (6) The printed edition reads: “Abu Dawud.” (7) The printed edition adds the honorific radiya Allahu ʿanhu (“may Allah be pleased with him”).
