٥ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ قَالَ قُلْتُ لأبِي الْحَسَنِ الرِّضَا (عَلَيهِ السَّلام) جُعِلْتُ فِدَاكَ اكْتُبْ لِي إِلَى إِسْمَاعِيلَ بْنِ دَاوُدَ الْكَاتِبِ لَعَلِّي أُصِيبُ مِنْهُ قَالَ أَنَا أَضَنُّ بِكَ أَنْ تَطْلُبَ مِثْلَ هَذَا وَشِبْهَهُ وَلَكِنْ عَوِّلْ عَلَى مَالِي.
5. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from Ahmad ibn Muhammad ibn abu Nasr who has said the following: “Once I said to abu al-Hassan al-Rida  ‘May Allah keep my soul in service for your cause, please write for me to Isma’il ibn Dawud al-Katib. 1 hope I will receive something from him.’ The Imam said, ‘I resent that you ask from him or similar persons. Allow it (financial help) to be paid from my property.’”
