Abu Hurairah narrated that the Rasulullah Sallallahu Alayhi Wasallam came across some people who were sitting, so he said:

‘Shall I not inform you of the best of you from your worst?'” He said: “They became silent, so he said that three times, then a man said: ‘Of course, O Messenger of Allah! Inform us of the best among us from our worst.’

He said: ‘The best of you is the one whose goodness is hoped for (people have hope in attaining some goodness from him), and people are safe from his evil.

And the worst of you is he whose goodness is not hoped for (people have no hope in attaining any goodness from him), and people are not safe from his evil.'”
