١ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ أَحْمَدَ بْنِ إِسْحَاقَ عَنْ بَكْرِ بْنِ مُحَمَّدٍ عَنْ أَبِي بَصِيرٍ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيهِ السَّلام) أُصُولُ الْكُفْرِ ثَلاثَةٌ الْحِرْصُ وَالإسْتِكْبَارُ وَالْحَسَدُ فَأَمَّا الْحِرْصُ فَإِنَّ آدَمَ (عَلَيهِ السَّلام) حِينَ نُهِيَ عَنِ الشَّجَرَةِ حَمَلَهُ الْحِرْصُ عَلَى أَنْ أَكَلَ مِنْهَا وَأَمَّا الإسْتِكْبَارُ فَإِبْلِيسُ حَيْثُ أُمِرَ بِالسُّجُودِ لآِدَمَ فَأَبَى وَأَمَّا الْحَسَدُ فَابْنَا آدَمَ حَيْثُ قَتَلَ أَحَدُهُمَا صَاحِبَهُ.
1. Al-Husayn ibn Muhammad has narrated from Ahmad ibn Ishaq from Bakr ibn Muhammad from abu Basir who has said the following: “Abu ‘Abd Allah  has said, ‘The roots of disbelief are three: Greed, Self- aggrandizement and Envy. It was greed that led Adam to eat from the prohibited tree. It was Self-aggrandizement that led Satan to refuse prostration before Adam. Envy led one of the sons of Adam to murder his own brother.’”
