5 - Narrated to us Muhammad bin Hasan (r.a.): Narrated to us Saad bin Abdullah: Narrated to us Abu Ja’far Muhammad bin Ahmad Alawi from Abil Hashim Dawood bin Qasim Ja’fari that he said: I heard Abal Hasan of Askar say: “The successor after me is my son al-Hasan but what will you do with the successor of my successor?” Al-Ja’fari said, “May Allah make me your sacrifice! Why?” The Imam said, “Because you will not see his physical body and it is not permissible for you to reveal his name.” Al-Ja’fari said, “How shall we mention him?” Al-Hadi said, “Say ‘The proof [al-Hujja] from the family of Muhammad.’”
