Musannaf Ibn Abi Shayba 33:21

34246. Marwan ibn Mu'awiyah narrated to us, from 'Awf, from 'Abbas al-'Ammi, who said: It reached me that Dawud (David), the Prophet, may Allah bless him and grant him peace, used to say in his supplication: "Glory be to You, O Allah, You are my Lord. You have exalted Yourself above Your Throne, and You have placed the fear of You upon those who are in the heavens and the earth. So, the closest of Your creation to You in rank are those who fear You the most. And what knowledge does he have who does not fear You? Or what wisdom does he have who does not obey Your command?"
