Musnad Ahmad 769:3

Waki’ narrated to us, al-A’mash narrated to us, from ‘Ubayd ibn al-Hasan al-Muzani, who said: I heard Ibn Abi Awfa saying: When the Messenger of Allah (peace and blessings of Allah be upon him) would raise his head from bowing, he would say: "Allah hears those who praise Him. O Allah, our Lord, to You is the praise, filling the heavens and filling the earth, and filling whatever else You will."
