Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) narrates: When the Prophet (peace and blessings be upon him) would go into bowing (ruku‘), he would recite:“O Allah! I have bowed for You, I have believed in You, I have submitted to You. My hearing, my sight, my marrow, my bones, and my tendons are humbled before You.”When he would raise his head from bowing, he would recite:“Allah has heard the one who praised Him. O our Lord, all praise is due to You, as much as would fill the heavens and the earth and whatever is between them, and as much as You will after that.”
