(1) Abu ʿAbd al-Raḥmān ʿAbd Allāh ibn al-Mubārak ibn Wāḍiḥ al-Ḥanẓalī al-Tamīmī al-Mawlā – known as al-Mawrāzī – was one of the foremost muhaddithīn (hadith scholars). He was born in 118 AH and died at Hīt on the Euphrates in 181 AH. His principal works include Kitāb al-Zuhd wa-l-Raqāʾiq, al-Musnad, and al-Birr wa-l-Ṣilah, among others. See: Ibn Abī Ḥātim, al-Jarḥ wa-l-Taʿdīl, vol. 1, pp. 262–281; al-Baghdādī, Tārīkh Baghdād, vol. 10, pp. 152–169; al-Ḏhahabī, Tadhkirat al-Ḥuffāẓ, vol. 1, pp. 274–282; Ibn Ḥajar, Tahḏīb al-Tahḏīb, vol. 5, pp. 382–387; and F. Sezgin, Geschichte des arabischen Schrifttums, “ʿUlūm al-Qurʾān wa-l-Ḥadīth,” vol. 1/1, p. 175. (2) Abū ʿAbd Allāh Sufyān ibn Saʿīd ibn Masrūq al-Thawrī was an eminent imam in hadith and other sciences, credited with the first thematic arrangement of ahādīth in Kūfa. He died in 161 AH. Among his works was al-Jāmiʿ, which is now lost. As M. Brockelmann notes in his History of Arabic Literature (vol. 3, p. 152), many early authors’ compilations, such as al-Jāmiʿ of al-Thawrī, have perished. See: Ibn Abī Ḥātim, al-Jarḥ wa-l-Taʿdīl, vol. 1, pp. 55–126; Ibn Khayr, al-Fihrista, pp. 136–137; Ibn Khallikān, Wafayāt al-Aʿyān, vol. 2, pp. 386–391; Ibn al-Nadīm, al-Fihrist, pp. 314–315; al-Zarkalī, al-Aʿlām, vol. 3, p. 158; Kihāla, Muʿjam al-Muʾallifīn, vol. 4, p. 234; Sezgin, Geschichte des arabischen Schrifttums, “Fiqh,” vol. 1/3, pp. 247–248; and Sezgin, “ʿUlūm al-Qurʾān wa-l-Ḥadīth,” vol. 1/1, p. 123. (3) Sufyān ibn ʿUyayna ibn Maymūn al-Hilālī Abū Muḥammad was the leading muhaddith of the Ḥaram. Born in Kufa in 107 AH and raised in Mecca, he died there in 198 AH. He authored a work titled al-Jāmiʿ in hadith, although Sezgin does not list it under that name; instead he records a manuscript simply called Ḥadīth, extant at al-Ẓāhiriyya. See: Sezgin, Geschichte des arabischen Schrifttums, “ʿUlūm al-Qurʾān wa-l-Ḥadīth,” vol. 1/1, pp. 178–179.
