Need for ruler to appoint just ministers

King not to gather ministers with corrupt inclinations (nor resign the affairs of state into others' hands), but instead those with faith and justice

"Beware, O King, that thou gather not around thee such ministers as follow the desires of a corrupt inclination, as have cast behind their backs that which hath been committed into their hands and manifestly betrayed their trust. Be bounteous to others as God hath been bounteous to thee, and abandon not the interests of thy people to the mercy of such ministers as these. Lay not aside the fear of God, and be thou of them that act uprightly. Gather around thee those ministers from whom thou canst perceive the fragrance of faith and of justice, and take thou counsel with them, and choose whatever is best in thy sight, and be of them that act generously.

"Know thou for a certainty that whoso disbelieveth in God is neither trustworthy nor truthful. This, indeed, is the truth, the undoubted truth. He that acteth treacherously towards God will, also, act treacherously towards his king. Nothing whatever can deter such a man from evil, nothing can hinder him from betraying his neighbour, nothing can induce him to walk uprightly.

"Take heed that thou resign not the reins of the affairs of thy state into the hands of others, and repose not thy confidence in ministers unworthy of thy trust, and be not of them that live in heedlessness. Shun them whose hearts are turned away from thee, and place not thy confidence in them, and entrust them not with thine affairs and the affairs of such as profess thy faith. Beware that thou allow not the wolf to become the shepherd of God's flock, and surrender not the fate of His loved ones to the mercy of the malicious. Expect not that they who violate the ordinances of God will be trustworthy or sincere in the faith they profess. Avoid them, and preserve strict guard over thyself, lest their devices and mischief hurt thee. Turn away from them, and fix thy gaze upon God, thy Lord, the All-Glorious, the Most Bountiful. He that giveth up himself wholly to God, God shall, assuredly, be with him; and he that placeth his complete trust in God, God shall, verily, protect him from whatsoever may harm him, and shield him from the wickedness of every evil plotter."
