It was narrated from ʿAli ؓ that The Prophet ﷺ used to say at the end of his Witr ʿO Allah, I seek refuge in Your pleasure from Your wrath, I seek refuge in Your forgiveness from Your punishment, I seek refuge in You from You. I cannot praise You enough, You are as You have praised Yourself.” (Using translation from Aḥmad 751)  

أَنَّ النَّبِيَّ ﷺ كَانَ يَقُولُ فِي آخِرِ وِتْرِهِ «اللهُمَّ إِنِّي أَعُوذُ بِرِضَاكَ مِنْ سَخَطِكَ وَبِمُعَافَاتِكَ مِنْ عُقُوبَتِكَ وَأَعُوذُ بِكَ مِنْكَ لَا أُحْصِي ثَنَاءً عَلَيْكَ أَنْتَ كَمَا أَثْنَيْتَ عَلَى نَفْسِكَ»
