3ـ ابْنُ أَبِي عُمَيْرٍ عَنْ إِبْرَاهِيمَ بْنِ عَبْدِ الْحَمِيدِ عَنْ يَعْقُوبَ الأحْمَرِ قَالَ قُلْتُ لأبِي عَبْدِ الله (عَلَيهِ السَّلام) إِنَّ عَلَيَّ دَيْناً كَثِيراً وَقَدْ دَخَلَنِي مَا كَانَ الْقُرْآنُ يَتَفَلَّتُ مِنِّي فَقَالَ أَبُو عَبْدِ الله (عَلَيهِ السَّلام) الْقُرْآنَ الْقُرْآنَ إِنَّ الآيَةَ مِنَ الْقُرْآنِ وَالسُّورَةَ لَتَجِي‏ءُ يَوْمَ الْقِيَامَةِ حَتَّى تَصْعَدَ أَلْفَ دَرَجَةٍ يَعْنِي فِي الْجَنَّةِ فَتَقُولُ لَوْ حَفِظْتَنِي لَبَلَغْتُ بِكَ هَاهُنَا.
3. Ibn abu ‘Umayr has narrated from Ibrahim ibn ‘Abd al-Hamid from Ya’qub al- Ahmar who has said the following: “Once I said to Abu ‘Abdillah (a.s.) ‘I am indebted a great deal and due to worries I am about to forget the Holy Quran. ’ The Imam (a.s.) said, ‘The Holy Quran, the Holy Quran! On the Day of Judgment the chapter and the verse of the Holy Quran will come and say, ‘Had you not forgotten me I would have taken you today to such and such high ranks in paradise.’”
