6ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنْ أَبِي خَالِدٍ الْقَمَّاطِ عَنْ حُمْرَانَ عَنْ أَبِي جَعْفَرٍ (عَلَيهِ السَّلام) قَالَ النَّدَامَةُ عَلَى الْعَفْوِ أَفْضَلُ وَأَيْسَرُ مِنَ النَّدَامَةِ عَلَى الْعُقُوبَةِ.
6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Muhammad ibn Sinan from abu Khalid al-Qammat from Humran from abu Ja’far (a.s.) who has said the following: “Abu Ja’far (a.s.) has said, ‘Regret for forgiving is better and easier than regret for being subjected to punishment.’”
