6ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ الله عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ رَجُلٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ مَنْ شَكَّ فِي الله بَعْدَ مَوْلِدِهِ عَلَى الْفِطْرَةِ لَمْ يَفِئْ إِلَى خَيْرٍ أَبَداً.
6. A number of our people have narrated from Ahmad ibn abu ‘Abd Allah from ‘Uthman ibn ‘Isa from a man from Abu ‘Abdillah عليه السلام who has said the following: “Abu ‘Abd Allah عليه السلام has said, ‘One who doubts in Allah after being born from Muslim parents, forever, will not end up to anything good.’”
