Ali ibn al-Yaqteen said, ‘I was (sitting) in the presence of the virtuous servant Musa ibn Ja’far (s). Then his son Al-Ridha (s) entered. Then he said, ‘O Ali! This is the master of my children. I have given him my nickname .’ Then Hisham hit himself on the forehead and said, ‘Woe! What did you say?’ Then Ali ibn Yaqteen said, ‘I swear by God that I heard him say (what I just told you).’ Then Hisham said, ‘By God, he has informed you that the affairs are entrusted to him (Imam al-Ridha) (after Imam Musa Al-Kadhim).’”
