Mubarak Ibn Faddalah says: I heard al-Hasan say the following: Death has shown the reality of this worldly life. It did not leave any happiness for those who are wise.
Thabet quotes al-Hasan as saying: The laughter of a believer is a sign of the inadvertence of his heart.
Talha Ibn Sabeeh says: al-Hasan said: A believer believes in what God has said. He is the best of men in his deeds, but he fears God most, so that if he spends the size of a mountain of money, he would not be sure of his reward until he sees this with his own eyes. The more righteous and charitable the believer is, the more afraid of God he becomes. While the hypocirte says: Men are too many, I shall be forgiven. There is no harm on me. Thus he acts badly, but wishes many things from God.
Faith is not mere wishes but what you have in your heart which is confirmed by your deeds. This means that deeds are the real test of faith.
