Musnad Ahmad 775:7

Abu Mu'awiyah narrated to us, Al-A'mash narrated to us, from 'Ubayd ibn al-Hasan, from 'Abdullah ibn Abi Awfa, who said: When the Messenger of Allah (peace and blessings of Allah be upon him) would say, "Allah hears those who praise Him," he would say, "O Allah, our Lord, to You is the praise, filling the heavens, and filling the earth, and filling whatever You will of anything after that."
