Musannaf Ibn Abi Shaybah

Hazrat Abdul Malik bin Suwaid Kahili narrates that Hazrat Ali (may Allah be pleased with him) recited these two parts while reading the Du'a Qunoot in the Fajr prayer: O Allah! We seek help from You, we seek forgiveness from You, we praise You for all good, we do not show ingratitude to You, we forsake and distance ourselves from those who disobey You. O Allah! We worship You alone, we pray for You, we prostrate before You. We walk towards You, we hope for Your mercy, we fear Your punishment, and surely Your punishment will overtake the disbelievers.
