When at the point of death, did Noushiravan counsel his son Hormuz:

“Cherish the poor, and seek not thine own comfort. The shepherd should not sleep while the wolf is among the sheep. Protect the needy, for a king wears his crown for the sake of his subjects. The people are as the root and the king is as the tree; and the tree, O son, gains strength from the root. He should not oppress the people who have fear of injury to his kingdom. Seek not plenteousness in that land where the people are afflicted by the king. Fear them that are proud and them that fear not God.”
