Ayesha (RA) said, I did not find Rasulullah (ﷺ) in bed one night. (In the dark) I searched for him. Then my hand touched the sole of his foot. He was then in prostration and his legs were erect. He was saying:

اَللَّهُمَّ إِنِّي أَعُوْذُ بِرِضَاكَ مِنْ سَخَطِكَ، وَبِمُعَافَاتِكَ مِنْ عُقُوبَتِكَ، وَأَعُوْذُ بِكَ مِنْكَ، لَا أُحْصِيْ ثَنَاءً عَلَيْكَ، أَنْتَ كَمَا أَثْنَيْتَ عَلَى نَفْسِكَ

Allaahumma 'innee 'a'oodhu biridhaaka min sakhatik, wa bimu'aafaatika min 'uqoobatik wa 'a'oodhu bika minka, laa 'uhsee thanaa'an 'alayka, 'Anta kamaa 'athnayta 'alaa nafsik

O Allah, I seek protection in Your pleasure from Your anger, and I seek protection in Your forgiveness from Your punishment. I seek protection in You from You. I cannot count Your praises. You are as You have praised Yourself.
