It is narrated from Imam Sadeq (AS) who narrated from Imam Ali (AS) who said: All the good things in life have been gathered in three characteristics; to look, to stay silent, and to speak. Therefore, any look/gaze without consideration and without learning a lesson from it, is an oversight. And any silence which is without thought/thinking is negligence. And any spoken word which does not remind me of God is futile. Blessed is the one whose every look is for learning a lesson; and his/her silence is contemplating; and his/her talk is to praise God; and cries for his/her own sins; and other people are safe from his/her wickedness .
