No leader of the people was able to control himself, his nerves, and his emotions as al-Hasan did during the attitudes from which he suffered. He tried hard to convince his loyal followers (Shi'a) when he endured their intense censure because of the Peace Treaty he made with Mu'awiya. Towards them, he took an attitude. The attitude indicated his angelic excellent qualities. In the mean time it indicated that he was an infallible Imam. That was when he controlled his anger, and possessed himself.
