9 - Narrated to us Muhammad bin Ibrahim bin Ishaq (r.a.): Informed us Ahmad bin Muhammad Hamadani: Narrated to us Ali bin Hasan bin Ali bin Faddal from his father from Hisham bin Saalim that: I asked As-Sadiq Ja’far bin Muhammad 
:
“Who is superior, Hasan or Husain? He replied: Hasan is superior to Husain. I said: Then how come the Imamate has come in the generations of Husain after him? And not in the generations of Hasan? The Imam said: Allah, the Mighty and Sublime wanted to effect the Sunnah of Musa and Harun in Hasan and Husain .
Have you not seen that they shared prophethood like Hasan and Husain shared Imamate and Allah, the Mighty and Sublime placed prophethood in the progeny of Harun and not in the progeny of Musa, even though Musa was superior to Harun ? I said: Would there be two Imams at the same time? He replied: No, except that one of them may be silent and under the command of the other. And the other will be the speaking Imam for his counterpart.
But as to whether there can be two speaking Imams at the same time? No. I said: Would Imamate be inherited between two brothers after Hasan and Husain ? He said: No, it will continue in the progeny of Husain like Allah, the Mighty and Sublime has said: And he made it a word to continue in his posterity. Thus Imamate will continue in his progeny generation after generation till the Judgment Day.”
