He said, ‘Do you know who I am?’ We said, ‘You are our Master and our elder.’ Then he said, ‘Tell me my name and my family.’ Then we said, ‘You are Musa ibn Ja’far ibn Muhammad صلى الله عليه وعلى آله وسلم.’ Then he asked, ‘Who is this with me?’ Then we said, ‘He is Ali ibn Musa ibn Ja’far صلى الله عليه وعلى آله وسلم.’ He said, ‘Then bear witness that he is my counsel in my life, and is my Testamentary Trustee after my death.’
