13ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عُمَرَ بْنِ أُذَيْنَةَ عَنِ الْفُضَيْلِ بْنِ يَسَارٍ قَالَ قُلْتُ لأبِي عَبْدِ الله (عَلَيهِ السَّلام) إِنَّ النَّاسَ يَقُولُونَ إِنَّ الْقُرْآنَ نَزَلَ عَلَى سَبْعَةِ أَحْرُفٍ فَقَالَ كَذَبُوا أَعْدَاءُ الله وَلَكِنَّهُ نَزَلَ عَلَى حَرْفٍ وَاحِدٍ مِنْ عِنْدِ الْوَاحِدِ.
13. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Umar ibn ‘Udhaynah from al-Fudayl ibn Yasar who has said the following: “Once, I said to Abu ‘Abdillah عليه السلام ‘People say that the Holy Quran was revealed upon seven letters.’ The Imam said, ‘They, the enemies of Allah, lie. It was revealed upon one letter from One source.’”
