Sayyiduna Anas (may Allah be pleased with him) transmits this saying of the Prophet (peace and blessings be upon him): "Shall I not tell you about the worst of you?" The people said: "Yes." The Prophet (peace and blessings be upon him) said: "The worst of you are those whose evil people try to guard against and from whom no good is expected; and the best of you are those from whom good is hoped and whose evil there is no need to guard against."
Abu Ya'la recorded it; its chain contains a narrator, Mubarak bin Suhaym, who is matruk (abandoned).
