H 11 - It is narrated from Muhammad bin Yahya from Ahmad bin Muhammad bin Isa from Hasan bin Mahbub from Husain bin Naeem Sahaf that he said: I, Hisham bin Hakam and Ali bin Yaqtin were in Baghdad, when Ali bin Yaqtin said: I was with Abdus Salih [Imam Musa Kadhim ] when his son, Ali entered. Imam said: O Ali bin Yaqtin, this Ali, is the chief of my children and I have given to him my agnomen (both were called Abul Hasan). [In another narration:] Hisham struck his face with the palm of his hand and said: Shame on you, how can you say that? ‘By God, I heard it from him, just as I said it,’ replied Ali bin Yaqtin. ‘Then, by God, the authority is for him after (Musa),’ said Hisham.
