The Sufficient (Vol 2) · Hadith 972 (#Ḥadīth #13)

13ـ عَنْهُ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنِ ابْنِ بُكَيْرٍ عَنْ أَبِي بَصِيرٍ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلام) يَقُولُ إِذَا أَذْنَبَ الرَّجُلُ خَرَجَ فِي قَلْبِهِ نُكْتَةٌ سَوْدَاءُ فَإِنْ تَابَ انْمَحَتْ وَإِنْ زَادَ زَادَتْ حَتَّى تَغْلِبَ عَلَى قَلْبِهِ فَلا يُفْلِحُ بَعْدَهَا أَبَداً.

13. It is narrated from him (narrator of the Hadith above) from Ahmad ibn Muhammad from ibn Faddal from ibn Bukayr from abu Basir who has said the following: “I heard Abu ‘Abdillah saying, ‘When a man commits a sin a black dot appears in his heart. If he then repents, the dot will disappear, if he commits more sins it will increase until it will take over his heart and he then will never have salvation.’”
