I asked Allah's Messenger (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.
Sahih Muslim Book 45, Hadith 16
← Previous Hadith Arn't you so and so? He said: Yes He gave him his donkey and said: Ride it, and tie the turban round your head. Some of his companions said: May Allah pardon you, you gave to this desert Arab the donkey on which you enjoyed ride for diversion and the turban which you tied round your. head. Thereupon he said: Verily I heard Allah's Messenger (ﷺ) as saying: The finest act of goodness is the kind treatment of a person to the loved ones of his father after his death and the father of this person was a friend of 'Umar.

Sahih Muslim Book 45, Hadith 15 Next Hadith → I stayed with Allah's Messenger (ﷺ) for one year. What obstructed me to migrate was (nothing) but (persistent) inquiries from him (about Islam). (It was a common observation) that when anyone of us migrated (to Medina) he ceased to ask (too many questions) from Allah's Messenger (ﷺ). So I asked him about virtue and vice. Thereupon Allah's Messenger (ﷺ) said: Virtue is a kind disposition and vice is what rankles in your mind and that you disapprove of its being known to the people.
