 ٥ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنِ الْمُفَضَّلِ بْنِ عُمَرَ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلام) قَالَ قُلْتُ لَهُ بِمَ يُعْرَفُ النَّاجِي قَالَ مَنْ كَانَ فِعْلُهُ لِقَوْلِهِ مُوَافِقاً فَأَثْبَتَ لَهُ الشَّهَادَةَ وَمَنْ لَمْ يَكُنْ فِعْلُهُ لِقَوْلِهِ مُوَافِقاً فَإِنَّمَا ذَلِكَ مُسْتَوْدَعٌ.
