5-3 Al-Mudhaffar ibn Ja’far Al-Alawi As-Samarqandi - may God be pleased with him - narrated that Ja’far ibn Muhammad ibn Mas’ood al-Ayyashi quoted on the authority of his father, on the authority Yusuf ibn As-Sakht, on the authority of Ali ibn Al-Qasim al-Uraydhi Al-Husseini, on the authority of Safwan ibn Yahya, on the authority of Abdurrahman ibn al-Hajjaj, on the authority of Ishaq and Ali - the sons of Abi Abdillah Ja’far ibn Muhammad (as-Sadiq) (s), “The year Musa ibn Ja’far (s) was arrested, we went to see Abdurrahman ibn Aslam in Mecca. We had a letter from Abil Hassan (Imam Kadhim) (s) in his own handwriting. There were instructions in the letter regarding what he needed. We told Abdurrahman ibn Aslam, ‘This way he has issued orders for these affairs. Then if there is anything related to these orders, give it to his son Ali (s) since he is his successor and he is in charge of his affairs.’” Then Ishaq and Ali added, “This conversation took place one day after the movement of the Hajj pilgrims from Mina to Mecca, and nearly fifty days after Abul Hassan (s) was arrested.” Ishaq and Ali, the sons of Abi Abdillah (s) had Al-Hussein ibn Ahmad al-Menqari, Isma’el ibn Umar, Has’san ibn Mo’awiya and Al-Hussein ibn Muhammad Sahib al-Khatm bear witness that Abul Hassan Ali ibn Musa was the Testamentary Trustee of his father (s) and was his successor. Two of them testified to this, and the other two said that he is the successor and his deputy. Then all their testimonies were accepted by the Judge Hafs ibn Ghiyath.
