An-Nawwas ibn Sam’an reported: I asked the Messenger of Allah, peace and blessings be upon him, about righteousness and sin. The Prophet said, “Righteousness is good character and sin is what waivers in your heart and you hate for people to find out about it.”

عَنِ النَّوَّاسِ بْنِ سَمْعَانَ الأَنْصَارِيِّ قَالَ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنِ الْبِرِّ وَالإِثْمِ فَقَالَ الْبِرُّ حُسْنُ الْخُلُقِ وَالإِثْمُ مَا حَاكَ فِي صَدْرِكَ وَكَرِهْتَ أَنْ يَطَّلِعَ عَلَيْهِ النَّاسُ 

صحيح مسلم كِتَاب الْبِرِّ وَالصِّلَةِ وَالْآدَابِ بَاب تَفْسِيرِ الْبِرِّ وَالْإِثْمِ 2553

Wabisa ibn Ma’bad reported: The Messenger of Allah, peace and blessings be upon him, said to him, “Have you come to ask about righteousness and sin?” I said yes. The Prophet clenched his fist and struck his chest three times, saying, “Consult your soul, consult your heart, O Wabisa. Righteousness is what is satisfying to your soul and your heart, and sin is what wavers in your soul and causes hesitancy in your chest, even if the people give you a judgment, and again give you a judgment.”
