Aḥmad b. Muḥammad b. Khālid b. ʿAbd al-Raḥmān al-Barqī (Arabic: احمد بن محمد بن خالد بن عبدالرحمن البرقي) (b. ~200/815-816 - d.274/887-888 or 280/893-894) was a renowned Twelver Shi'a muhaddith (hadith scholar) and historian of 3rd/9th century. Both Shi'a and Sunni scholars have relied on his hadiths. His most important work is al-Mahasin.
Al-Barqi was born around 200/815-816 in Kufa.
- His son, 'Abd Allah b. Ahmad al-Barqi
- His uncles, Hasan b. Khalid and Fadl b. Khalid
- His grandsons, Ahmad b. 'Abd Allah b. Ahmad and 'Ali b. Muhammad b. Majilawayh
- His son-in-law, Muhammad b. Abu l-Qasim Majilawayh
- His cousin, 'Ali b. 'Ala' b. Fadl b. Khalid
- His great grandson, 'Ali b. Ahmad b. 'Abd Allah b. Ahmad al-Barqi
Scholars of rijal regard al-Barqi as one of the disciples of Imam al-Jawad (a) and Imam al-Hadi (a), but there is no mention of these two Imams (a) in al-Barqi's narrations. It just mentioned in a hadith that in a travel to Samarra, a Courier came from "the Man" and according to evidences, "the man" was Imam al-hadi (a).
All the major shi'a scholars like al-Najashi, al-Shaykh al-Tusi and al-'Allama al-Hilli have praised al-Barqi and considered him as a reliable narrator. Al-Barqi also has a special position among the Sunnis.
Narrating from Unreliable Narrators and Being Banished from Qom
The fact that al-Barqi used to narrate from unreliable narrators and take mursal hadiths as reliable hadiths caused that Ahmad b. Muhammad b. 'Isa al-Ash'ari the head of hadith scholars of Qom, banish al-Barqi from Qom but after a while al-Ash'ari returned al-Barqi to Qom and apologized him. Al-Ash'ri participated in al-Barqi's funeral bareheaded (without 'imama (turban) ) and barefoot to show his sorrow and compensate his previous action.
A Response to the Criticism of Narrating from Unreliable Narrators
Wahid Bihbahani writes: Al-Barqi is certainly reliable and what the critics say is not proved and even if he trusted in unreliable narrators, we can just say that his approach in narrating hadith is not right 
Al-Barqi has narrated approximately from 200 persons and mentioned about 100 books in the field. Ayatollah Khoei has discussed about them several times in his book.
