Nafi' mawla Ibn Umar

Nafi' (full kunya Abu Abd Allah al-Madani) was a leading traditionist of the Tabi'un — the generation of Muslims who knew the Prophet Muhammad's Companions but not the Prophet himself. He worked in Medina in the Hijaz (western Arabia). Tradition holds he was a non-Arab captive taken in the early conquests and then freed (made a mawla, a client or freedman) by Abdullah ibn Umar, son of the second caliph; the precise place he came from is reported differently by different early sources and is not securely known.

Nafi' attached himself to Ibn Umar for decades and became the principal transmitter of his teacher's reports about the Prophet's words and practice (hadith). Through his own students — above all Malik ibn Anas, founder of the Maliki school of law, alongside Ibn Shihab al-Zuhri and Ayyub al-Sakhtiyani — his material spread across the emerging discipline of hadith. Sunni scholars, including al-Bukhari, judged the chain "Malik, from Nafi', from Ibn Umar" the soundest of all transmission lines and nicknamed it the silsilat al-dhahab, the "golden chain." Reports praising Nafi' (such as Malik's remark that he needed no other source once Nafi' had spoken) come from the biographical-praise tradition and express scholarly esteem rather than independent fact.

Modern Western scholarship has debated his role: G.H.A. Juynboll questioned whether Nafi' was a genuine historical "common link," while Harald Motzki and others defended the authenticity of material traced to him. He died in Medina, with the year variously given as 117, 119, or 120 AH (c. 735–738 CE).
