Abu Az-Zubair

Abu al-Zubayr Muhammad ibn Muslim ibn Tadrus al-Makki was a Tabi'i scholar of Mecca who became one of the primary transmitters from the companion Jabir ibn Abdillah al-Ansari, may Allah be pleased with him. He narrated an enormous number of hadiths from Jabir and is the main channel through which many of Jabir's reports reached Imam Muslim — who transmitted more hadiths from Abu al-Zubayr than almost any other source. He also narrated from Ibn Abbas, Ibn Umar, and other companions. Hadith scholars engaged in some discussion about his reliability: most accepted him as trustworthy, though Imam Shu'ba raised concerns about his practice of sometimes narrating from Jabir without explicit statement of direct hearing, suggesting occasional tadlis (concealment of a weak link). Despite this, Imam Muslim relied on him extensively, and later scholars largely accepted his narrations. His reports are central to Sahih Muslim and appear in other major collections. He lived in Mecca and passed away around 126 AH. Without Abu al-Zubayr, a significant portion of Jabir ibn Abdillah's narrations would not have been preserved in the canonical form in which they are known today.
