1ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ وَسَهْلِ بْنِ زِيَادٍ جَمِيعاً عَنِ ابْنِ مَحْبُوبٍ عَنْ جَمِيلِ بْنِ صَالِحٍ عَنِ الْفُضَيْلِ بْنِ يَسَارٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ سَمِعْتُهُ يَقُولُ إِنَّ الَّذِي يُعَالِجُ الْقُرْآنَ وَيَحْفَظُهُ بِمَشَقَّةٍ مِنْهُ وَقِلَّةِ حِفْظٍ لَهُ أَجْرَانِ.
1. A number of our people have narrated from Ahmad ibn Muhammad and Sahl ibn Ziyad all from ibn Mahbub from Jamil ibn Salih from al-Fudayl ibn Yasar who has said the following: “I heard Abu ‘Abdillah (a.s.) saying, ‘Those who face difficulty memorizing the Holy Quran due to lesser ability of memorization will be rewarded twofold.’”
