Others In terms of Ihsan: Nafi bin Sarjis Abu Abdullah ad-Dailami (Arabic: نافع بن سارجيس أبو عبد الله الديلمي), also known as Nafi` Mawla ibn `Umar (Arabic: نافع مولى بن عمر), was a scholar of Fiqh jurisprudence and muhaddith from the Tabiun generation who resided in Medina.
Nafi was originally a resident of Daylam (now including the Gilan region in Iran) who was captured during Muslim conquest of Persia and became a slave before being manumitted by Abdullah ibn Umar.
[5] Malik even goes as far as to say, "If I heard (hadith) from Nafi' narrating from Ibn Umar, I would not care if I did not hear it from someone else(as it is undoubtly authentic).
"[citation needed] Scholars such as al-Bukhari, al-Asqalani and Abu Ali al-Khalil have high confidence for hadiths authenticity narrated by Nafi.
[6] Ze'ev Maghen stated the authenticity of Nafi narration were "almost peerless",[7] while Professor Bashar Awad, editor of Tirmidhi collection,[8] and winner of King Faisal Prize award,[9] also noted the "golden chain" of Nafi were often supported with validation by another Tabi'un-to-Sahabah chains.
