حَدَّثَنَا مُحَمَّدُ بْنُ الْحَسَنِ رَضِيَ اللَّهُ عَنْهُ قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ جَعْفَرٍ الْحِمْيَرِيُّ قَالَ حَدَّثَنَا أَحْمَدُ بْنُ إِسْحَاقَ قَالَ: خَرَجَ عَنْ أَبِي مُحَمَّدٍ عليه السلام إِلَى بَعْضِ رِجَالِهِ فِي عَرْضِ كَلَامٍ لَهُ مَا مُنِيَ أَحَدٌ مِنْ آبَائِي عليه السلام بِمَا مُنِيتُ بِهِ مِنْ شَكِّ هَذِهِ الْعِصَابَةِ فِيَّ فَإِنْ كَانَ هَذَا الْأَمْرُ أَمْراً اعْتَقَدْتُمُوهُ وَ دِنْتُمْ بِهِ إِلَى وَقْتٍ ثُمَّ يَنْقَطِعُ فَلِلشَّكِّ مَوْضِعٌ وَ إِنْ كَانَ مُتَّصِلًا مَا اتَّصَلَتْ أُمُورُ اللَّهِ عَزَّ وَ جَلَّ فَمَا مَعْنَى هَذَا الشَّكِّ.
Narrated to us Muhammad bin Hasan 
: Narrated to us Abdullah bin Ja’far Himyari: Narrated to us Ahmad bin Ishaq that: Imam Hasan al-Askari wrote a letter to a person in which it was mentioned: “Such doubt as was observed in my Imamate, was not present in the case of any of my forefathers. Thus if this matter of Imamate is as you believe, there is scope for doubt in it, but if this matter is related to Allah, the Mighty and Sublime there is no scope for doubt.”
