The reason for the arrest of Musa bin Ja’far (a.s) was that Harun Rashid had put his son in the care of Ja’far bin Muhammad bin Ashath and Yahya bin Khalid Barmaki 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 bin Muhammad - and the latter used to believe in 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 reported back to H¡r£n Rashid and he added to these reports that which would make (Harun Rashid) feel hatred towards him. One day (Yahya bin Khalid) asked some of those he trusted: “Would you find 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 to Ali bin Ismail bin Ja’far bin Muhammad. Yahya bin Khalid took him some money. Musa (a.s) was friendly with Ali bin Ismail bin Ja’far bin Muhammad, used to bring him gifts and treat him well. Yahya bin Khalid sent to (Ali bin Ismail) requesting him to visit Harun Rashid and drawing his attention to the kind treatment, which he had given him. So he decided to do that. Musa (a.s) was concerned and summoned Ali. “Where are you going, cousin?” he asked. “Baghdad,” was the reply. “Why are you doing that?” he enquired. “I am in debt and I am poor,” he answered. “I will pay your debt and act for you and carry out (what you need),” Musa (a.s) told him. He did not pay attention to that and began to set about (preparing for his) departure. Abul Hasan (a.s) asked him to come and said to him: “Are you leaving?” “Yes,” he replied, “I must do that.” “Look, cousin,” he said to him, “fear God and do not give away any confidences against my children.” He ordered him to be given three hundred dinars and four thousand dirhams. (When he stood up in front of him) Abul Hasan Musa (a.s) spoke to those who were present: “By God, he will strive against my blood and will confide against my children.” “May God make us your ransom,” they said, “did you know this from his state when you were giving him gifts and being generous to him?” “Yes,” he said, “my father told me on the authority of his ancestors, on the authority of the Messenger of Allah (s) that when kin cut themselves away, then they should be brought back, for if they cut themselves away, God will cut them off. I wanted to bring him back after he had cut himself off from me for if he cuts me off, God will cut him off. Ali bin Ismail set out until he reached Yahya bin Khalid. He gave him news of Musa bin Ja’far (a.s) and (Yahya bin Khalid) reported to Harun Rashid and added additional material to it. Then he took him to Harun Rashid. The latter asked him about his uncle and he gave information against him to (Harun Rashid). He told him that money was being brought to him from east and west and that he had bought an estate named Al-Yasir for thirty thousand dinars. Its (former) owner had said when he had brought him the money: “I will not accept this currency. I will only accept such-and-such currency.” Then he ordered that money be brought and gave thirty thousand dinars of the currency whose coinage he had asked for. Harun Rashid listened to that and then ordered him to be given two hundred thousand dirhams, with which he sought to make a living in one of the areas. He chose one of the provinces of the east. His messengers were sent to bring the money and he waited there for its arrival. One day he went to the toilet when he was suffering from dysentery and as a result of it the whole of his stomach came out. He fell down. They tried to put it back, but they could not. He was aware of his situation when the money was brought to him while he was in the pangs of death. He said: “What can I do with it? I am about to die.” That year Harun Rashid went on the pilgrimage. He began it at Medina and there he had Abul Hasan Musa (a.s) arrested. It is reported that when he came to Medina, Musa (a.s) received him with a group of nobles. They had gone out to meet him and then Abul Hasan (a.s) had gone on to the mosque as was his custom. Harun Rashid waited until night and then went to the tomb of the Messenger of Allah (s). He said: “O Messenger of Allah (s), I apologize to you for something I want to do. I want to imprison Musa Ibn Ja’far, because he intends to divide your community and cause bloodshed.” Then he ordered him to be taken from the mosque and brought before him. He had him put in chains and called for two awnings to be brought. He had (Abul Hasan) put in one of them on a mule and had the other awning put on another mule. The two mules left his house carrying the two awnings, which were closed. With each one went the cavalry. The cavalry divided and some went with one awning on road to Basra and the other to Kufa. Harun Rashid only did that in order to confuse the people about what had happened to Abul Hasan (a.s). He ordered the men who were with the awning in which was Abul Hasan to hand him over to Isa bin Ja’far bin Mansur, who was governor of Basra at that time. He was handed over to him and he kept him in detention for a year. He then wrote a letter to Harun saying, “You may take him (i.e. Imam Kadhim) from me and hand him over to any other person; otherwise, I will release him. I have tried all means to find any overwhelming evidence against him, but I failed. In fact, I even eavesdropped on him hoping that I would hear him invoking God’s curse upon me or you, but I always heard him supplicating God for himself and imploring Him for mercy and forgiveness. So, Harun order someone to go and receive the Imam from Isa. The Imam was then detained with al-Fadhl ibn al-Rabi in Baghdad where he spent a very long time of detention. However, Harun wanted al-Fadhl to kill the Imam, but the later refused. As a result, Harun ordered him through a letter to give the Imam to al-Fadhl ibn Yahya who also refused to obey Harun's orders of killing the Imam. Harun, while residing in al-Riqqah, was then informed that the Imam was living in luxury under the custody of al-Fadhl ibn Yahya; so, he ordered his servant Masrur to go to Baghdad, immediately come to Musa ibn Jaffar and gather information about his actual situation there. Harun instructed, “If you see him enjoy luxury as has been told, you mus then take this letter of mine to Abbas ibn Muhammad and take this another letter to Sindi ibn Shahak and order both of them to carry out my instruction mentioned in these letters immediately.” Obeying his master, Masrur came to Baghdad and resided in the house of al-Fadhl ibn Yahya without letting anyone know what he had come for. He then visited Musa ibn Jaffar and found him enjoying luxury, as exactly as Harun had been told. As soon as he left, he headed for Abbas and Sindi and delivered them the two letters of Harun. At once, the messenger left for al-Fadhl ibn Yahya running. When he was there, the people noticed that al-Fadhl rode with the messenger while he was overcome by astonishment and surprise. Once he met Abbas, he asked for lashes and a lashing wood. He assigned the mission to Sindi and ordered that al-Fadhl should be stripped of his clothes and lashed one hundred lashes. When he left, al-Fadhl was extremely astounded that he unconsciously went on greeting people. Masrur the servant transmitted this news to Harun in a letter and the latter ordered him to had over Imam Musa Kadhim (a.s) to Sindi ibn Shahak. Harun gathered the people and delivered a speech, saying, “O people, al-Fadhl ibn Yahya has disobeyed and challenged my orders. So, I see that you should invoke curse on him.” Cries of curse on al-Fadhl were uttered by all people from every corner of Harun's house that shook with these cries. Upon receiving these news, Yahya ibn Khalid came to Harun and entered from another door than the one usually used by people. He thus surprised Harun from his back and said to him, “Would you please listen to me, O Amir al-Mu'minin?” Panicked by this move, Harun paid his attention to Yahya who said to him, “It is true that al-Fadhl has committed a mistake, but we can set aright what he has ruined.” These words gladdened Harun who thus turned his face towards the attendants and said to them, “Because al-Fadhl had disobeyed me, I asked you to invoke curse upon him. Now that he repented and returned to my obedience, you should now accept him as your chief.” Acceding to him, the attendants shouted, “We always are friends of those whom you befriends and enemies of those whom you alienate. So, we are now loyalists to al-Fadhl.” Yahya ibn Khalid himself undertook the mission of transferring the ruler’s letters. When he arrived in Baghdad, the people surged and began to doubt everything. So, Yahya had to pretend that he had come for setting aright all their affairs and observing the performance of the governmental officials. While he was implementing some of these reformations, he summoned Sindi and conveyed to him the instructions of the ruler. Of course, Sindi went on carrying out these instructions. At the hour of his death, Imam Musa (a.s) asked Sindi to bring to him one of his servants who lived in the house of Abbas ibn Muhammad so that he would perform the ritual bathing of his body after his death. Sindi did. The reporter added: I asked Imam Kadhim (a.s) to allow me to enshroud him, but he refused and said, “We, the Ahl al-Bayt, manage the affairs of the dowries of our wives, our journeys to the Hajj pilgrimage and the shrouds that are used for enshrouding our dead bodies from our purest legally gotten money. I have my own shroud.” When the Imam passed away, master scholars and celebrated personalities of Baghdad, one of whom was al-Haytham ibn Adi, were allowed to see his dead body so that they would witness that he was not killed; rather, his death was natural. His dead body was then taken out and put on the bridge. A caller shouted, “This is the body of Musa ibn Jaffar. You people may come and look at it.” So, the people came to look at his face fixedly. The Reporter added: A man from the descendants of Ali ibn Abi Talib reported to me that the caller who stood on the dead body of Imam Kadhim shouted, “This is Musa ibn Jaffar whom the Rafidah claim that he would not die. Come on and look at him.” So, people came and gazed at the body. The Imam’s body was then carried and buried in the cemetery of Quraysh; so, his grave was next to a man from the Nawfar family, whose name was Isa ibn Abdullah.”
