 ٥ـ أَحْمَدُ بْنُ إِدْرِيسَ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنِ الْحَسَنِ بْنِ الْحُسَيْنِ اللُّؤْلُؤِيِّ عَنْ يَحْيَى بْنِ عَمْرٍو عَنْ دَاوُدَ الرَّقِّيِّ قَالَ قُلْتُ لابِي الْحَسَنِ مُوسَى (عَلَيْهِ السَّلام) إِنِّي قَدْ كَبِرَتْ سِنِّي وَدَقَّ عَظْمِي وَإِنِّي سَأَلْتُ أَبَاكَ (عَلَيْهِ السَّلام) فَأَخْبَرَنِي بِكَ فَأَخْبِرْنِي مَنْ بَعْدَكَ فَقَالَ هَذَا أَبُو الْحَسَنِ الرِّضَا.
 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 , ‘I have grown old and my bones are weakening. I asked your father  and he informed me about you. Would you also inform me (about the Imam after you).” The Imam  said, “This abu al-Hassan al-Rida.”
