Musannaf Ibn Abi Shayba 21:247

Sufyan ibn 'Uyaynah narrated to us, from Mis'ar, from the one who heard al-Sha'bi saying: The Greatest Name of Allah... Then he recited, or it was recited to him: "He is Allah, the Creator, the Inventor, the Fashioner; to Him belong the best names. Whatever is in the heavens and earth is exalting Him. And He is the Exalted in Might, the Wise." And when a man supplicates, he should increase [his supplication].
