It is narrated from Abu Hurairah (may Allah be pleased with him) that when the Messenger of Allah (ﷺ) performed prostration, he would say: "O Allah! For You I have prostrated, and to You I have submitted, and in You I have believed, and You alone are my Lord. My face has prostrated to the One who created it and fashioned its hearing and sight. Blessed is Allah, the Best of creators."
