It is narrated from Sayyidah Asma' bint Yazid (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) said: "O people! Shall I not tell you about the best of you?" The people said: "Certainly." He (peace and blessings be upon him) said: "Those who, when they are seen, Allah is remembered. Shall I not tell you about the worst of you?" The people said: "Certainly." He (peace and blessings be upon him) said: "The worst of you are those who go about spreading tale-bearing, who sow discord between loved ones, and who seek hardship and faults for the innocent."
