Chapter 185 | About the Darkness of the Heart of the Hypocrite Even Though He Has a Tongue and the Light of the Heart of the Believer Even Though His Tongue May Fall Short
3ـ 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.’”
