2. A number of our people has narrated Ahmad ibn Muhammad from Ali ibn al-Hakam from Abu Ayyub al-Khazzaz from Thubayt from Mua‘dh ibn Kathir who has said the following: "I said to Abu ‘Abdallah (a.s.), ‘I pray to Allah who has granted your father because of you such a high position to grant you also such high position through your successor before you will leave this world.' He then said, 'Allah has already granted such favor.' The narrator has said that he then asked the Imam (a.s.), 'Who is he, ‘May I be your ransom?' He pointed out towards the pious servant (of Allah), who was asleep, saying this man who is asleep. He was a young boy.”

3. Through the same chain of narrators it is narrated from Ahmad ibn Muhammad who has said the following. “Abu Ali al-Arjani al-Farisi narrated to me from ‘Abd al-Rahman al- Hajjaj in the year ( 179 AH /795 AD) in which former abu al-Hasan, Imam Musa (a.s.) was detained. I (Hajjaj) said to him (‘Abd al-Rahman), “This man (abu al-Hassan Musa (a.s.) has been detained in his (Mansur, current ruler) hands. We do not know how his conditions are. Have you heard anything from him about his sons?” He (‘Abd al-Rahman) said to me, “I did not think anyone would ask me about this issue. Once I went to see Ja‘far ibn Muhammad (a.s.) in his home. He was in such and such a room at the prayer area. He was praying to Allah and on his right side was Musa ibn Ja‘far (a.s.) saying Amen for his prayer. I said to him, ‘May Allah take my soul in service for your cause, you know my having cutoff from all others to serve you, who will be the Wali Leader with Divine Authority for people after you?” He replied, “Musa has dressed up in this coat of arms and it has perfectly fitted him.” I then said to him, “I will not need anything after this.”

Ahmad ibn Mihran has narrated from Muhammad ibn Ali from Ya‘qub ibn Ja‘far al-Ja‘fari who has said that Ishaq ibn Ja‘far (a.s.) said to me the following. “One day I was in the presence of my father that Ali ibn ‘Umar ibn Ali asked him this question. “‘May Allah take my soul in service for your cause, “from who should we seek help and the people seek help and assistance after you (leave this world)?” He (The Imam (a.s.) said, you must seek refuge and guidance from the man who has two yellow clothes on him and a twine bunch of hair who will shortly appear to you from this door, opening the both halves of the door with his hand together.” We did not wait very long that there appeared two palms holding both halves of the door and opened them. Thereafter came to us abu Ibrahim (a.s.).”
