The reason for al-Rashid detaining Abu al-Hasan Musa, peace be on him,
imprisoning him and killing him is (contained in what is mentioned in the
following tradition).
[Ahmad ibn Ubayd Allah ibn 'Ammar reported on the authority of 'Ali ibn Muhammad al-Nawfah on the authority of his father; and Ahmad ibn Muhammad ibn Sa'd (reported); and Abu Muhammad al-Hasan ibn Muhammad ibn Yahya: on the authority of their teachers, who said:]'
The reason for the arrest of Musa ibn Ja’far, peace be on them, was that al- Rashid had put his son in the care of Ja'far ibn Muhammad ibn al-Ash'ath and Yahya. ibn Khalid ibn Barmak was jealous of that. He said (to himself): “If the caliphate passes on to (the son), my dominion and that of my son will be destroyed.”
Therefore he deceived Ja’far ibn Muhammad - and the latter used to maintain the belief in the Imamate - so that he managed to gain access to him and establish friendly relations with him. His visits to his house were frequent and he became acquainted with his affairs, which he would report back to al-Rashid and he used to add to these reports that which would make (al-Rashid) feel hatred towards him.
One day (Yahya ibn Khalid) asked some of those he trusted: “Would you discover for me a member of the family of Abu Talib who is not in comfortable circumstances, and then he would let me know what I need?”
He was directed towards 'Ali ibn Ismail ibn Ja’far ibn Muhammad. Yahya ibn Khalid took him some money. Musa, peace be on him, was friendly with `Ali ibn Isma'il ibn Ja'far ibn Muhammad and he used to bring him gifts and treat him well.
