٣ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنِ ابْنِ مَحْبُوبٍ عَنْ أَبِي حَمْزَةَ الثُّمَالِيِّ عَنْ أَبِي جَعْفَرٍ (عَلَيهِ السَّلام) قَالَ الْقُلُوبُ ثَلاثَةٌ قَلْبٌ مَنْكُوسٌ لا يَعِي شَيْئاً مِنَ الْخَيْرِ وَهُوَ قَلْبُ الْكَافِرِ وَقَلْبٌ فِيهِ نُكْتَةٌ سَوْدَاءُ فَالْخَيْرُ وَالشَّرُّ فِيهِ يَعْتَلِجَانِ فَأَيُّهُمَا كَانَتْ مِنْهُ غَلَبَ عَلَيْهِ وَقَلْبٌ مَفْتُوحٌ فِيهِ مَصَابِيحُ تَزْهَرُ وَلا يُطْفَأُ نُورُهُ إِلَى يَوْمِ الْقِيَامَةِ وَهُوَ قَلْبُ الْمُؤْمِنِ. 
3. A number of our people have narrated from Sahl ibn Ziyad from ibn Mahbub from abu Hamza al-Thumali from abu Ja’far  who has said the following: “Hearts are of three kinds: an upside down heart that holds nothing good is the heart of an unbeliever. The heart in which there is a black dot, thus, good and evil duel therein. Whichever dominates the heart defeats the other. There is the open heart. In it lamps shine and its light does not extinguish until the Day of Judgment and that is the heart of a believer.’”
