I asked Messenger of Allah ﷺ about virtue and vice. He said: Virtue is a kind disposition and vice is what rankles in your heart and that you disapprove that people should come to know of it. (Using translation from Muslim 2553a)

أَنَّهُ سَأَلَ رَسُولَ اللهِ ﷺ عَنِ الْبِرِّ وَالْإِثْمِ فَقَالَ الْبِرُّ حُسْنُ الْخُلُقِ وَالْإِثْمُ مَا حَاكَ فِي نَفْسِكَ وَكَرِهْتَ أَنْ يَطَّلِعَ النَّاسُ عَلَيْهِ
