It is narrated from Hasan that he says: Hazrat Ali (may Allah be pleased with him) said: Glad tidings are for every unknown person who recognizes people but people do not recognize him. And Allah Almighty recognizes him with His pleasure. These are the lamps of guidance. Every dark trial is removed through them, and Allah Almighty admits them into His mercy. These people do not reveal secrets, nor are they harsh or show off.
