It is narrated from Asma bint Yazid (may Allah be pleased with her) that she heard the Messenger of Allah (peace and blessings be upon him) say: "Shall I not tell you about the best among you?" The companions (may Allah be pleased with them) said: "O Messenger of Allah! Please do tell us." He (peace and blessings be upon him) said: "The best among you are those who, when they are seen, Allah is remembered." Hasan, narrated by Ibn Majah.
