٥ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ الْقَاسِمِ بْنِ حَبِيبٍ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ إِنَّ الله جَبَلَ النَّبِيِّينَ عَلَى نُبُوَّتِهِمْ فَلا يَرْتَدُّونَ أَبَداً وَجَبَلَ الأوْصِيَاءَ عَلَى وَصَايَاهُمْ فَلا يَرْتَدُّونَ أَبَداً وَجَبَلَ بَعْضَ الْمُؤْمِنِينَ عَلَى الإيمَانِ فَلا يَرْتَدُّونَ أَبَداً وَمِنْهُمْ مَنْ أُعِيرَ الإيمَانَ عَارِيَّةً فَإِذَا هُوَ دَعَا وَأَلَحَّ فِي الدُّعَاءِ مَاتَ عَلَى الإيمَانِ. 
5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from al-Husayn ibn Sa’id from al-Qasim ibn Habib from Ishaq ibn ‘Ammar from Abu ‘Abdillah  who has said the following: ‘‘Allah has formed the prophets upon their prophet-hood, thus they never, turn away therefrom. He has formed the successors of the prophets upon their successor-ship and they never turn away therefrom. He has formed certain believers upon belief and they never turn away therefrom. Belief in certain ones among them is deposited and if he prays persistently he dies upon belief.”
