Musnad Ahmad 25:647

Ibn Abi Bukayr narrated to us, Ibrahim—meaning Ibn Nafi‘—narrated to us, from Wahb ibn Minas al-‘Adani, from Sa‘id ibn Jubayr, from Ibn ‘Abbas: That the Prophet, peace and blessings of Allah be upon him, when he intended to prostrate after the bowing, 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."
