الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ جُمْهُورٍ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ عَبْدِ الْمُؤْمِنِ عَنْ سَالِمٍ قَالَ سَأَلْتُ أَبَا جَعْفَرٍ عَنْ قَوْلِ الله عَزَّ وَجَلَّ ثُمَّ أَوْرَثْنَا الْكِتابَ الَّذِينَ اصْطَفَيْنا مِنْ عِبادِنا فَمِنْهُمْ ظالِمٌ لِنَفْسِهِ وَمِنْهُمْ مُقْتَصِدٌ وَمِنْهُمْ سابِقٌ بِالْخَيْراتِ بِإِذْنِ الله قَالَ السَّابِقُ بِالْخَيْرَاتِ الامَامُ وَالْمُقْتَصِدُ الْعَارِفُ لِلامَامِ وَالظَّالِمُ لِنَفْسِهِ الَّذِي لا يَعْرِفُ الامَامَ.
Hadith No. 2
Al-Husayn has narrated from Mu‘alla from al-Washsha’ from ‘Abd al-Karim from Sulayman who has said that he asked abu ‘Abdallah about the meaning of the following verse of the Holy Quran. “We gave the book as an inheritance to Our chosen servants,.. .” (35:3) The Imam asked, “What do you say about it?” I said, “We say that they are the Fatimid (descendents of Fatima, Daughter of the Holy Prophet (s.a.)” The Imam said, “It is not as you say. No one who would point out his sword and call people into schism and misguidance comes in this (category of people exceeding in virtue).” I then asked, “Who then are the ones doing wrong to themselves?” The Imam replied, “It is those who sit in their homes and do not know the rights of his Imam . The moderate ones are those who know the rights of their Imam and the ones exceeding in virtue are the Imams ”
الْحُسَيْنُ عَنْ مُعَلىً عَنِ الْوَشَّاءِ عَنْ عَبْدِ الْكَرِيمِ عَنْ سُلَيْمَانَ بْنِ خَالِدٍ عَنْ أَبِي عَبْدِ الله قَالَ سَأَلْتُهُ عَنْ قَوْلِهِ تَعَالَى ثُمَّ أَوْرَثْنَا الْكِتابَ الَّذِينَ اصْطَفَيْنا مِنْ عِبادِنا فَقَالَ أَيَّ شَيْءٍ تَقُولُونَ أَنْتُمْ قُلْتُ نَقُولُ إِنَّهَا فِي الْفَاطِمِيِّينَ قَالَ لَيْسَ حَيْثُ تَذْهَبُ لَيْسَ يَدْخُلُ فِي هَذَا مَنْ أَشَارَ بِسَيْفِهِ وَدَعَا النَّاسَ إِلَى خِلافٍ فَقُلْتُ فَأَيُّ شَيْءٍ الظَّالِمُ لِنَفْسِهِ قَالَ الْجَالِسُ فِي بَيْتِهِ لا يَعْرِفُ حَقَّ الامَامِ وَالْمُقْتَصِدُ الْعَارِفُ بِحَقِّ الامَامِ وَالسَّابِقُ بِالْخَيْرَاتِ الامَامُ.

الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ عَنْ أَحْمَدَ بْنِ عُمَرَ قَالَ سَأَلْتُ أَبَا الْحَسَنِ الرِّضَا عَنْ قَوْلِ الله عَزَّ وَجَلَّ ثُمَّ أَوْرَثْنَا الْكِتابَ الَّذِينَ اصْطَفَيْنا مِنْ عِبادِنا الايَةَ قَالَ فَقَالَ وُلْدُ فَاطِمَةَ (عليها السلام) وَالسَّابِقُ بِالْخَيْرَاتِ الامَامُ وَالْمُقْتَصِدُ الْعَارِفُ بِالامَامِ وَالظَّالِمُ لِنَفْسِهِ الَّذِي لا يَعْرِفُ الامَامَ.

Those who disbelieve the Book are certainly losers.” (2:2) The Imams said that such people are the Imams .”
مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ عَنْ أَبِي وَلادٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله عَنْ قَوْلِ الله عَزَّ وَجَلَّ الَّذِينَ آتَيْناهُمُ الْكِتابَ يَتْلُونَهُ حَقَّ تِلاوَتِهِ أُولئِكَ يُؤْمِنُونَ بِهِ قَالَ هُمُ الائِمَّةُ (عَلَيْهم السَّلام)
