I heard Imam Hasan Askari (a.s) say: Among the sins that would not be forgiven is when a person says: If only I were not punished, except for this sin! I said to myself: This matter is very complicated and it is best for man to be wary of his self in his internal matters in everything. At that moment the Imam glanced at me and said: O Abdul Hashim, you thought right. You must be careful of every incident and matter, because polytheism in people is more concealed than the movement of the ant on a smooth stone on a dark night or on the surface of black floor.
