Musannaf Ibn Abi Shayba 3:4516

Ibn Fudayl narrated to us, from ‘Ata’ ibn al-Sa’ib, from Abu ‘Abd al-Rahman, who said: Ibn Mas’ud taught us to recite in the Qunut: "O Allah, we seek Your help and we seek Your forgiveness, and we believe in You, and we praise You with goodness, and we do not disbelieve in You, and we cast off and abandon whoever acts wickedly against You. O Allah, You alone we worship, and for You we pray and prostrate, and towards You we strive and hasten, and we hope for Your mercy and fear Your punishment; for Your true punishment will surely overtake the disbelievers."
