The Prophet ﷺ used to say in his prostration, "Allah, to You I have prostrated, in You I have believed, and to You I have submitted. You are my Lord. My face has prostrated to the One who created and shaped it, and who opened its hearing and sight. Blessed is Allah, the best of creators."
عن النبي ﷺ أنه كان يقول في سجوده: اللهم لك سجدت، وبك آمنت، ولك أسلمت، وأنت ربي سجد وجهي للذي خلقه وصوره، وشق سمعه وبصره، تبارك الله أحسن الخالقين.
Nasai (1127) narrated it from Yahya bin Uthman, who said, Abu Haywa informed us, who said, Shuayb bin Abu Hamza narrated to us, from Muhammad bin Munkadir, from Jabir bin Abdullah, from the Prophet ﷺ, and he related the hadith. Its chain is sahih.
