عَلِيُّ بْنُ مُحَمَّدٍ عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ عَلِيِّ بْنِ أَسْبَاطٍ عَنْ عَمِّهِ يَعْقُوبَ بْنِ سَالِمٍ عَنْ دَاوُدَ بْنِ فَرْقَدٍ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) إِنَّ أَبِي كَانَ يَقُولُ إِنَّ اللَّهَ عَزَّ وَ جَلَّ لَا يَقْبِضُ الْعِلْمَ بَعْدَ مَا يُهْبِطُهُ وَ لَكِنْ يَمُوتُ الْعَالِمُ فَيَذْهَبُ بِمَا يَعْلَمُ فَتَلِيهِمُ الْجُفَاةُ فَيَضِلُّونَ وَ يُضِلُّونَ وَ لَا خَيْرَ فِي شَيْءٍ لَيْسَ لَهُ أَصْلٌ
Ali Bin Muhammad, from Sahl Bin Ziyad, from Ali Bin Asbat, from his uncle Yaqoub Bin Salim, from Dawood Bin Farqad who said,
Abu Abdullah-asws said: ‘My-asws father-asws was saying: ‘Allah-azwj Mighty and Majestic does not Capture the knowledge after having Sent it down, but He-azwj Causes the death of a scholar, so he goes away with whatever he knew and the vanities follow them (the people), so they would be straying and causing others to be straying, and there is no goodness in something which does not originate from its ‘أَصْلٌ’ source (the Divine Knowledge)’’.[1]
الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ أَحْمَدَ بْنِ إِسْحَاقَ عَنْ بَكْرِ بْنِ مُحَمَّدٍ عَنْ أَبِي بَصِيرٍ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) أُصُولُ الْكُفْرِ ثَلَاثَةٌ الْحِرْصُ وَ الِاسْتِكْبَارُ وَ الْحَسَدُ فَأَمَّا الْحِرْصُ فَإِنَّ آدَمَ ( عليه السلام ) حِينَ نُهِيَ عَنِ الشَّجَرَةِ حَمَلَهُ الْحِرْصُ عَلَى أَنْ أَكَلَ مِنْهَا وَ أَمَّا الِاسْتِكْبَارُ فَإِبْلِيسُ حَيْثُ أُمِرَ بِالسُّجُودِ لآِدَمَ فَأَبَى وَ أَمَّا الْحَسَدُ فَابْنَا آدَمَ حَيْثُ قَتَلَ أَحَدُهُمَا صَاحِبَهُ
Al Husayn Bin Muhammad, from Ahmad Bin Is’haq, from Bakr Bin Muhammad, from Abu Baseer who said,
Abu Abdullah-asws (6th Imam) said: ‘أُصُولُ’ The origins of the disbelief are three – the greed, and the arrogance, and the envy. So, as for the greed, so when Adam-as was Forbidden from the tree, the greed carried him-as upon eating from it; and as for the arrogance, so when Iblees-la was Commanded with the prostration to Adam-as, he-la refused; and as for the envy, so when the two sons of Adam-as, one of the two killed his companion.[2]
