SHAFAQNA – Imam Ali (AS) addressing Malik Ashtar said: As far as your are able, join the pious and truthful people (those who tell the truth, genuine people), and guide them in a way that they do not praise you a lot, and they do not encourage you to bad deeds which you have not committed yet, because excessive praise will lead to selfishness and make the human being to rebel [1].
