Musannaf Ibn Abi Shaybah 7069 — The supplication of qunut in witr

Abdullah bin Ubayd bin Umayr said that Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) used to recite this supplication in the qunut of witr: "O Allah, to You belongs praise filling the seven heavens and the seven earths, and filling all that is between them. You are worthy of praise and glory; this is the truest thing a servant has said, and all of us are Your servants. None can withhold what You give, and none can give what You withhold, and the wealth of a wealthy person avails him nothing against You."
