12ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنْ أَبِي دَاوُدَ الْمُسْتَرِقِّ عَنْ عَلِيِّ بْنِ مَيْمُونٍ عَنِ ابْنِ أَبِي يَعْفُورٍ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلام) يَقُولُ ثَلاثَةٌ لا يَنْظُرُ الله إِلَيْهِمْ يَوْمَ الْقِيَامَةِ وَلا يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ مَنِ ادَّعَى إِمَامَةً مِنَ الله لَيْسَتْ لَهُ وَمَنْ جَحَدَ إِمَاماً مِنَ الله وَمَنْ زَعَمَ أَنَّ لَهُمَا فِي الاسْلامِ نَصِيباً.
12. Al-Husayn ibn Muhammad has narrated from Mu‘alla ibn Muhammad from abu Dawud al-Mustariqq fromAli ibn Maymun from ibn abu Ya‘fur who has said the following. “I heard abu ‘Abdallah عليه السلام say, ‘There will be three kinds of people to whom Allah will not look on the Day of Judgment, will not purify them and they will suffer pain full punishments. They are those who claim to be the Imam with authority from Allah, those who would reject the Imam, Leader with Divine Authority and those who think that for the two there is a share in Islam.”
