“Once I came face to face to Abu ‘Abdillah (a.s.) on a road and I turned my face away and passed him by. Later I went to see him and said, ‘May Allah keep my soul in service for your cause, I sometimes may turn my face away and pass you so as not to cause you any trouble. ’ The Imam said, ‘May Allah grant you blessings, however, yesterday a man passed by me in such and such place and said, ‘Upon you be peace, O abu ‘Abd Allah.’ What he did was not any good or beautiful.’”
