Narrated from Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) came to a group of people who were sitting and stopped by them and said: "Shall I not tell you who among you are the best and who among you are the worst?" The people remained silent. He repeated this three times. One man said: "O Messenger of Allah! Certainly, do tell us who among us are the best and who among us are the worst." He said: "The best among you is the one from whom good is expected and people are safe from his evil, and the worst among you is the one from whom no good is expected and people are not safe from his evil." __REF_N__ Imam Tirmidhi says: This hadith is Hasan Sahih.
