ʿAbd al-Raḥmān ibn ʿUmar, descendant of the exemplary imām Muḥammad ibn al-Munkadir, the Qurashī, the Taymī, the Madinan—known as al-Munkadirī—who later settled in Khurasan.
He studied under ʿAbd al-Jabbār ibn al-ʿAlāʾ—the earliest of his shaykhs—Yūnus ibn ʿAbd al-Aʿlā, Hārūn ibn Isḥāq al-Hamdānī, ʿAlī ibn Ḥarb, Abū Zurʿa al-Rāzī, and many others of their rank from among the pupils of Sufyān ibn ʿUyayna, Wakīʿ, and Yazīd ibn Hārūn.
Transmitters from him include Muḥammad ibn Ṣāliḥ ibn Hāniʾ, Muḥammad ibn Khālid al-Muṭṭaʿwī al-Bukhārī, the ḥadith master Muḥammad ibn Maʾmūn al-Marwazī, a large number of others, his son ʿAbd al-Wāḥid, and Muḥammad ibn ʿAlī ibn Shāh.
He undertook far-reaching journeys, travelling widely in both his youth and his old age.
Al-Ḥākim said, “He possesses singular reports and remarkable narrations.”
The author adds: He appears in Tarīkh Dimashq because he heard hadith in Beirut from al-ʿAbbās ibn al-Walīd, and in Shīrāz from Isḥāq ibn Shādhān.
He resided for a time in Basra, then in Isfahan, then in Rayy, and finally in Nīshāpūr.
He died in Marw in 314 AH, at a little over eighty years of age.
