Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) narrates: When the Prophet Muhammad (peace be upon him) would raise his head from bowing during prayer, he would recite: "O Allah! O our Lord! All praise is due to You, as much as would fill the heavens, as much as would fill the earth, and as much as would fill whatever else You will after that."
