(1) ʿUthman b. ʿUrwa b. al-Zubayr b. al-ʿAwwam (al-Asadi al-Qurashi), the brother of Hisham, was a reliable and exacting transmitter. Al-Bukhari, Muslim and others relate from him. A noted orator and scholar, he died in 136 AH/754 CE. See: Tahdhib al-Tahdhib 7:138, no. 287. (2) ʿUrwa b. al-Zubayr b. al-ʿAwwam (al-Asadi al-Qurashi) was one of the foremost of the second-generation Successors (tabiʿun), a jurist, scholar and ascetic, trustworthy and prolific in hadith. He died in 93 AH/712 CE. See: Tahdhib al-Tahdhib 7:180, 185, no. 351. (3) The eminent Companion al-Zubayr b. al-ʿAwwam b. Khuwaylid al-Qurashi (Abu ʿUrwa), grandfather of the above-mentioned Hisham and ʿUthman, was a cousin and close disciple (hawari) of the Prophet, one of the ten promised Paradise and a member of the six-man shura council. He accepted Islam early, migrated twice, and fought in every campaign. At the Battle of the Camel (36 AH/656 CE) he withdrew after ʿAli reminded him of a prophetic warning, but Ibn Jurmuz pursued and killed him. See: al-Isaba 1:545, no. 2789. (4) This hadith has already been discussed (p. 200); see Sunan al-Nasaʾi 8:137–138. (5) MS Ṭ reads: “Both versions are unauthenticated,” the same wording found in Sunan al-Nasaʾi 8:138. (6) The reference is to the hadith master ʿAli b. ʿUmar al-Baghdadi, known as al-Daraqutni (306–385 AH/918–995 CE), a Shafiʿi jurist and author of the Sunan and al-Mukhtalif wa-l-Muʾtalif. See: Wafayat al-Aʿyan 3:297–298, no. 434; al-Lubab fi Tahdhib al-Ansab 1:483. (7) A mursal hadith is one whose chain omits the Companion. Ibn Taymiyya defines it: “A mursal report is that which is narrated by someone other than a Companion, and he may have taken it from another.” See: Majmuʿ al-Fatawa 18:38; Tadrib al-Rawi 1:195-196.
