٥ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ يَحْيَى بْنِ الْمُبَارَكِ عَنْ عَبْدِ الله بْنِ جَبَلَةَ عَنْ مُعَاوِيَةَ بْنِ وَهْبٍ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قُلْتُ لَهُ جُعِلْتُ فِدَاكَ إِنِّي أَحْفَظُ الْقُرْآنَ عَلَى ظَهْرِ قَلْبِي فَأَقْرَؤُهُ عَلَى ظَهْرِ قَلْبِي أَفْضَلُ أَوْ أَنْظُرُ فِي الْمُصْحَفِ قَالَ فَقَالَ لِي بَلِ اقْرَأْهُ وَانْظُرْ فِي الْمُصْحَفِ فَهُوَ أَفْضَلُ أَ مَا عَلِمْتَ أَنَّ النَّظَرَ فِي الْمُصْحَفِ عِبَادَةٌ. 
5. A number of our people have narrated from Sahl ibn Ziyad from Yahya ibn al- Mubarak from ‘Abd Allah ibn Jabalah from Mu’awiyah ibn Wahab from Ishaq ibn ‘ Ammar who has said the following: “Once I said to Abu ‘Abdillah  ‘May Allah keep my soul in service for your cause, I memorize the Holy Quran by heart and read from my memory, is that more virtuous or looking on a copy of the Holy Quran?’ The narrator has said that the Imam said to me, ‘It is better to look in a copy. Have you not heard that looking at a copy of the Holy Quran is an act of worship?”’
