When prostrating #1
At-Tirmidhi 2:474
سَجَدَ وَجْهِيَ لِلَّذِي خَلَقَهُ، وَشَقَّ سَمْعَهُ وَبَصَرَهُ، بِحَوْلِهِ وَقُوَّتِهِ، فَتَبَارَكَ اللَّهُ أَحسَنُ الْخَالِقِينَ
I have prostrated my face to the One Who created it, and gave it hearing and sight by His might and His power. Glory is to Allah, the Best of creators.
