My face has prostrated to the One Who created it and shaped it and shaped it well, and brought forth its hearing and sight. Blessed be Allah the best of Creators.)"  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا سَجَدَ يَقُولُ اللَّهُمَّ لَكَ سَجَدْتُ وَلَكَ أَسْلَمْتُ وَبِكَ آمَنْتُ سَجَدَ وَجْهِي لِلَّذِي خَلَقَهُ وَصَوَّرَهُ فَأَحْسَنَ صُورَتَهُ وَشَقَّ سَمْعَهُ وَبَصَرَهُ تَبَارَكَ اللَّهُ أَحْسَنُ الْخَالِقِينَ

My face has prostrated to the One who created it, and fashioned it, and opened its hearing and sight. Blessed is Allah, the Best of creators."
