the commander of the faithful عليه السلام said: men are of three kinds: intelligent, foolish and corrupt sinner, as for the intelligent one the religion is his path, and forbearance is his habit, and giving counsel is his disposition, when he is asked he answers, and when he speaks he is to the point, and when he hears he comprehends, and when he reports he is truthful, and when one confides in him he is loyal, as for the fool if someone alerts him to a beautiful thing he overlooks it, and if he is dissuaded from good he acquiesces to forsake it, and if he is driven to ignorance he becomes ignorant, and if he reports he is incorrect, he does not understand and if perchance he is able to understand he does not learn from it, and as for the corrupt sinner if you rely on him he betrays you, and if you befriend him he hates you, and if you trust him he is not sincere with you.
