 ١٣ـ إِسْحَاقُ قَالَ حَدَّثَنِي الْحَسَنُ بْنُ ظَرِيفٍ قَالَ اخْتَلَجَ فِي صَدْرِي مَسْأَلَتَانِ أَرَدْتُ الْكِتَابَ فِيهِمَا إِلَى أَبِي مُحَمَّدٍ (عَلَيْهِ السَّلام) فَكَتَبْتُ أَسْأَلُهُ عَنِ الْقَائِمِ (عَلَيْهِ السَّلام) إِذَا قَامَ بِمَا يَقْضِي وَأَيْنَ مَجْلِسُهُ الَّذِي يَقْضِي فِيهِ بَيْنَ النَّاسِ وَأَرَدْتُ أَنْ أَسْأَلَهُ عَنْ شَيْ‏ءٍ لِحُمَّى الرِّبْعِ فَأَغْفَلْتُ خَبَرَ الْحُمَّى فَجَاءَ الْجَوَابُ سَأَلْتَ عَنِ الْقَائِمِ فَإِذَا قَامَ قَضَى بَيْنَ النَّاسِ بِعِلْمِهِ كَقَضَاءِ دَاوُدَ (عَلَيْهِ السَّلام) لا يَسْأَلُ الْبَيِّنَةَ وَكُنْتَ أَرَدْتَ أَنْ تَسْأَلَ لِحُمَّى الرِّبْعِ فَأُنْسِيتَ فَاكْتُبْ فِي وَرَقَةٍ وَعَلِّقْهُ عَلَى الْمَحْمُومِ فَإِنَّهُ يَبْرَأُ بِإِذْنِ الله إِنْ شَاءَ الله يا نارُ كُونِي بَرْداً وَسَلاماً عَلى‏ إِبْراهِيمَ فَعَلَّقْنَا عَلَيْهِ مَا ذَكَرَ أَبُو مُحَمَّدٍ (عَلَيْهِ السَّلام) فَأَفَاقَ.
 13. Ishaq has said that al-Hassan ibn al-Zarif narrated to me the following. “Two issues would poke in my chest which made me to write to abu Muhammad . I wrote about Al-Qa’im (the one who will rise with Divine Authority). “When he rise by what means he will judge among the people and where will be his court house?” I also wanted to ask him about alternating fever but I had missed to mention it in writing. The answer came. “You had asked about Al-Qa’im. When he will rise he judge among people through his own knowledge just the way David would judge. He would not call any witness to testify. You also wanted to ask about alternating fever but you forgot to do so. Write this on a sheet (of material) “We said to the fire, ‘Be cool and peaceful (with Abraham)’” (21:69).The narrator has said that we did just as he had said and the suffering person was relieved.”
