Musannaf Ibn Abi Shayba 3:4653

Waki’ narrated to us, he said: Ja’far ibn Burqan informed us, from Maymun ibn Mihran, regarding the recitation of Ubayy ibn Ka’b: "O Allah, we seek Your help and we seek Your forgiveness, and we praise You 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 to You we strive and hasten, and we hope for Your mercy and we fear Your punishment; indeed, Your punishment will overtake the disbelievers."
