On Imam Al-kazim’s صلى الله عليه وعلى آله وسلم Clear Appointment of Imam al-Ridha صلى الله عليه وعلى آله وسلم

4-5 In another tradition we read that my father - may God be pleased with him - narrated that Al-Hassan ibn Muhammad ibn Abdullah ibn Isa quoted on the authority of his father, on the authority of Al-Hassan ibn Musa al-Khashshab, on the authority of Muhammad ibn al-Asbaq, on the authority of Uthman ibn al-Qasim, “Mansoor ibn Yunus bin Bozorj told me that once he went to visit Abul Hassan, that is Imam Musa ibn Ja’far (al-Kadhim) صلى الله عليه وعلى آله وسلم. Imam Al-Kadhim صلى الله عليه وعلى آله وسلم said, ‘O Mansoor! Do you know what I have done today?’ Mansoor said, ‘No.’ Imam Al-Kadhim صلى الله عليه وعلى آله وسلم said, ’I have appointed my son Ali as my Testamentary Trustee, and my successor after me.’ Then Mansoor said, ‘I then went to see Al-Ridha صلى الله عليه وعلى آله وسلم and congratulated him صلى الله عليه وعلى آله وسلم this. I let him know that his father had instructed me to do so.’ However, Mansoor later denied this, confiscated the property that he had control over, and spent it.”
