Imam Ali (a.s.) points to a truth worth sitting with: at a time when virtue is in vogue in the world and among people, if a person entertains an evil suspicion about another person from whom nothing evil has ever been seen, then he has been unjust. and at a time when vice is in vogue in the world and among people, if a man entertains a good idea about another person, he flings himself in peril.

Do one small act today whose reward is in the Hereafter.
