5. Ahmad ibn Idris has narrated from Muhammad ibn ‘Abd al-Jabbar from al-Hassan ibn al-Husayn al-Lu’lu’i from Yahya ibn ‘Amr from Dawud al-Raqqi who has said the following. “I said to abu al-Hassan aMusa (a.s.), ‘I have grown old and my bones are weakening. I asked your father (a.s.) and he informed me about you. Would you also inform me (about the Imam after you).” The Imam (a.s.) said, “This abu al-Hassan al-Rida.”
