It is narrated from Hazrat Ibn Abi Awfa (may Allah be pleased with him) that when the Noble Prophet (peace and blessings be upon him) would raise his head from bowing (ruku), he would say "Sami' Allahu liman hamidah" and then say: "O our Lord Allah! All praise is for You, equal to the fullness of the heavens and the earth, and equal to the fullness of whatever else You will."
