 ٦ـ عَنْهُ بِإِسْنَادِهِ عَنْ أَحْمَدَ بْنِ عُمَرَ الْحَلالِ قَالَ قُلْتُ لابِي الْحَسَنِ الرِّضَا (عَلَيْهِ السَّلام) الرَّجُلُ مِنْ أَصْحَابِنَا يُعْطِينِي الْكِتَابَ وَلا يَقُولُ ارْوِهِ عَنِّي يَجُوزُ لِي أَنْ أَرْوِيَهُ عَنْهُ قَالَ فَقَالَ إِذَا عَلِمْتَ أَنَّ الْكِتَابَ لَهُ فَارْوِهِ عَنْهُ.
 6. It is narrated from him from Ahmad ibn ‘Umar al-Hallal who has said the following. “I said to (Imam) abu al-Hassan al-Rida , ‘One of our people gives me a book but he does not say whether I can narrate any thing from it or not. Can I narrate from it?’” He has said that the Imam  said, “Yes, you can narrate if you would that the book is his.”
