Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to say these words at the end of Witr: O Allah! I seek refuge in Your pleasure from Your displeasure. I seek refuge in Your forgiveness from Your punishment. I seek refuge in You from You. I cannot enumerate Your praises; I praise You only as You have praised Yourself.
