I said to Abu Ja’far Muhammad bin Ali al-Jawad (as): Who is the successor after you?” He said: “My son Ali and Ali’s two sons.” He pondered for a while and then raised his head and said: “Confusion will occur then.” I said: “If that occurs, where will we go then?” He kept silent and then said: “Nowhere!” He repeated it three times. I repeated my question. He said: “To Medina.” I said: “Which Medina?” He said: “This Medina. Is there another one than ours?” The same was narrated by Ali bin Ahmad from Obaydillah bin Musa from Ahmad bin al-Husayn from Ahmad bin Hilal from Umayya bin Ali al-Qayssi.
