Sahih Adab al-Mufrad

It is narrated from Sayyidah Asma bint Yazid (may Allah be pleased with her) that she said: The Prophet (peace and blessings of Allah be upon him) said: “Shall I not tell you who are the best among you?” The people said: Yes. He said: “Those people who, when they are seen, Allah is remembered.” He said: “Shall I not tell you who are the worst among you?” The people said: Yes. He said: “Those who spread gossip, those who create discord among friends, and those who seek out faults in innocent people (seekers of sins).”
