Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) narrates: When the Prophet Muhammad (peace and blessings be upon him) would go into prostration during obligatory prayer, he would recite: "O Allah! I have prostrated for You, I have believed in You, and I have submitted to You. You are my Lord. My face is prostrated before the One who created it, shaped it, and granted it hearing and sight. So blessed is Allah, the Best of Creators." When the Prophet Muhammad (peace and blessings be upon him) would go into bowing (ruku'), he would recite: "O Allah! I have bowed for You alone, I have believed in You, I have submitted to You. You are my Lord. My hearing, my sight, my brain, my bones, my entire being is humbled before Allah, the Lord of all the worlds." When the Prophet Muhammad (peace and blessings be upon him) would raise his head from bowing during obligatory prayer, he would recite: "O Allah, O our Lord! All praise is exclusively for You, praise that fills the heavens, fills the earth, and fills whatever else You will." The chain of this narration is authentic and good.
