Wanting to advise his son Hasanرضي الله عنه, Hazrat Aliرضي الله عنه said, "My son: Beware of three, be in harmony with three, be modest before three, race to three, flee from three, be in disagreement with three, fear three, and hope of three."
"O my father, please explain," said Hazrat Hasanرضي الله عنه
"Beware of pride, anger, and the base kind of ambition. Live in harmony with Allah's Book, His Messenger's sunnah, and the lives of His righteous slaves. Hurry away from sinning, race to repentance and sprint forward in the pursuit of knowledge. My son, flee from lying, treachery and transgression. Be in disagreement with evil and its people, hypocrisy and its people, and foolishness and its people. Fear Allah, fear the company of those who do not fear Allah, and fear the evil speech of your tongue. Hope for Allah to forgive your sins, to accept your deeds, and to accept the intercession of your Nabi."
