Chapter 111 | The Sins
28ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ رَفَعَهُ قَالَ قَالَ أَمِيرُ الْمُؤْمِنِينَ (عَلَيهِ السَّلام) لا وَجَعَ أَوْجَعُ لِلْقُلُوبِ مِنَ الذُّنُوبِ وَلا خَوْفَ أَشَدُّ مِنَ الْمَوْتِ وَكَفَى بِمَا سَلَفَ تَفَكُّراً وَكَفَى بِالْمَوْتِ وَاعِظاً.
28. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus in a marfu’ manner from Amir al-Mu’minin, Ali ibn abu Talib who has said the following: “No pain is more painful to the heart than sins and there is no fear more intense than fear of death. Past experience is enough material for thinking and death is more than enough a preacher.”
