Musannaf Ibn Abi Shayba 3:78

Hafs narrated to us, from al-A’mash, from Ibrahim, from al-Aswad, who said: Umar began the prayer, then he said the takbir, then he said: "Glory be to You, O Allah, and with Your praise, and blessed is Your name, and exalted is Your majesty, and there is no god other than You. I seek refuge in Allah from the accursed Satan. Praise be to Allah, Lord of the worlds."
