9ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ عَلِيِّ بْنِ النُّعْمَانِ عَنْ إِسْمَاعِيلَ بْنِ جَابِرٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلام) قَالَ كِتَابُ الله فِيهِ نَبَأُ مَا قَبْلَكُمْ وَخَبَرُ مَا بَعْدَكُمْ وَفَصْلُ مَا بَيْنَكُمْ وَنَحْنُ نَعْلَمُهُ.
9. A number of our people has narrated from Ahmad ibn Muhammad ibn ‘Isa from Ali ibn Ni‘man from ’Isma‘il ibn Jabir from abu ‘Abdallah عليه السلام who has said the following. “In the book of Allah there is the news of things before you, the reports of the matters after you and the laws to settle your disputes and we know it all.”
