اللَّهُمَّ لَكَ سَجَدْتُ وَبِكَ آمَنْتُ, وَلَكَ أَسْلَمْتُ, سَجَدَ وَجْهِيَ لِلَّذِي خَلَقَهُ, وَصَوَّرَهُ, وَشَقَّ سَمْعَهُ وَبَصَرَهُ, تَبَارَكَ اللَّهُ أَحْسنُ الْخَالِقينَ

(O Allah, I take refuge within Your pleasure from Your displeasure and within Your pardon from Your punishment, and I take refuge in You from You. I cannot enumerate Your praise. You are as You have praised Yourself.)
