 ٦ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلام) قَالَ إِنَّ الله تَبَارَكَ وَتَعَالَى أَدَّبَ نَبِيَّهُ (صَلَّى اللهُ عَلَيْهِ وَآلِه) فَلَمَّا انْتَهَى بِهِ إِلَى مَا أَرَادَ قَالَ لَهُ إِنَّكَ لَعَلى‏ خُلُقٍ عَظِيمٍ فَفَوَّضَ إِلَيْهِ دِينَهُ فَقَالَ وَما آتاكُمُ الرَّسُولُ فَخُذُوهُ وَما نَهاكُمْ عَنْهُ فَانْتَهُوا وَإِنَّ الله عَزَّ وَجَلَّ فَرَضَ الْفَرَائِضَ وَلَمْ يَقْسِمْ لِلْجَدِّ شَيْئاً وَإِنَّ رَسُولَ الله (صَلَّى اللهُ عَلَيْهِ وَآلِه) أَطْعَمَهُ السُّدُسَ فَأَجَازَ الله جَلَّ ذِكْرُهُ لَهُ ذَلِكَ وَذَلِكَ قَوْلُ الله عَزَّ وَجَلَّ هذا عَطاؤُنا فَامْنُنْ أَوْ أَمْسِكْ بِغَيْرِ حِسابٍ.
