Abu al-Hasan Ali ibn Yaqteen ibn Musa al-Baghdadi (742–798) (Persian:ابوالحسن علی بن یقطین بن موسی البغدادی) was a close companion of Imam Musa al-Kadhim, a Shia narrator, jurist, and mutakallim.[1] He was born in Kufa and lived in Baghdad. He was a reliable minister of Abbasid Caliphate, however he kept his faith hidden and used his position in the government administration to support the Shia who were usually oppressed during the Abbasid reign. He compiled 3 books.
Ali ibn Yaqteen was born in 742 in Kufa. Since his father,, was one of the supporters of Imam Ja'far al-Sadiq, he was placed under an arrest warrant by Marwan I. Therefore, he was forced to escape and hide, and Ali ibn Yaqteen's mother took him and his brother, Ubayd, to Medina. Later on, he moved to Baghdad and started working as a spice seller.[2]
After the fall of the Umayyad Caliphate and emergence of Abbasid Caliphate, Ali ibn Yaqteen returned to Kufa and entered the Abbasid administration. He got promoted when Al-Hadi took over the reign. He was even entrusted with the special Caliph ring and seal. In the long run, he became a minister of Harun al-Rashid.[3]
Undoubtedly he was a Shia; but he hid his belief from Abbasid Caliphs all the time as his father did. He was a close student and companion to Musa al-Kadhim and acted as Musa al-Kadhim's secret agent in the palace of Harun al-Rashid. Many Hadiths have been narrated from him in The Four Books. According to some historical evidence that have been given credence by Shia scholars, he entered the Abbasid government by the approval and guidance of Musa al-Kadhim in order to support the oppressed people and particularly assist the Shia.[4] [5]
In biographical evaluation sources, three books have been mentioned for him:
In 798 Ali ibn Yaqteen died in Baghdad while Musa al-Kadhim was imprisoned by Harun al-Rashid.[7]
