Sunan at-Tirmidhī Ḥadīth [2263] – The Best of You From the Worst…
It is narrated on the authority of Abī Hurayrah (may Allāh be pleased with him) that the Messenger of Allāh (peace and blessings of Allāh be upon him) 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 Allāh! Inform us of the best among us from our worst.’ He said: “The best of you is the one whose goodness is hoped for, and people are safe from his evil. And the worst of you is he whose goodness is not hoped for, and people are not safe from his evil.”
