What Should One Say In Prostration ?

Narrated Aisha, Ummul Mu'minin:

The Messenger of Allah ﷺ prostrated himself at night when reciting the Qur'an. He said repeatedly: My face prostrates itself to Him Who created it and brought forth its hearing and seeing by His might and power.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا إِسْمَاعِيلُ، حَدَّثَنَا خَالِدٌ الْحَذَّاءُ، عَنْ رَجُلٍ، عَنْ أَبِي الْعَالِيَةِ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتْ كَانَ رَسُولُ اللَّهِ ﷺ يَقُولُ فِي سُجُودِ الْقُرْآنِ بِاللَّيْلِ يَقُولُ فِي السَّجْدَةِ مِرَارًا " سَجَدَ وَجْهِي لِلَّذِي خَلَقَهُ وَشَقَّ سَمْعَهُ وَبَصَرَهُ بِحَوْلِهِ وَقُوَّتِهِ " .
