Supplications for prostrations due to recitation of the Quran
 

"سَجَدَ وَجْهِيَ لِلَّذِي خَلَقَهُ، وَشَقَّ سَمْعَهُ وَبَصَرَهُ، بِحَوْلِهِ وَقُوَّتِهِ، فَتَبَارَكَ اللهُ أَحسَنُ الْخَالِقِينَ".

50. Sajada wajhiya lillathee khalaqahu, wa shaqqa sam'ahu wa basarahu bihawlihi wa quwwatihi. Fatabaarakallaahu 'ahsanul-khaaliqeen.

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.

Reference: At-Tirmithi 2/474, Ahmad 6/30, and Al-Hakim

"اللَّهُمَّ اكْتُبْ لِي بِهَا عِنْدَكَ أَجْراً، وَضَعْ عَنِّي بِهَا وِزْراً، وَاجْعَلْهَا لِي ذُخْراً، وَتَقَبَّلْهَا مِنِّي كَمَا تَقَبَّلْتَهَا مَنْ عَبْدِكَ دَاوُدَ".

51. Allaahum-maktub lee bihaa 'indaka 'ajran, wa aha' 'annee bihaa wizran, waj'alhaa lee 'indaka thukhran, wa taqabbalhaa minnee kamaa taqabbaltahaa min'abdika Daawooda.

O Allah, write it as a reward for me, and release me from a burden for it, and make it a I treasure for me in Paradise. Accept it from me as You accepted it from your servant Dawud.

Reference: At-Tirmithi 2/473, and Al-Hakim who graded it authentic and Ath-Thahabi agreed 1/219.
