What supplication did the Messenger of Allah [SAW] say the most before he died? She said: "The supplication that he said the most was: 'Allahumma, inni a'udhu bika min sharri ma 'amiltu wa min sharri ma lam a'mal ba'd (O Allah, I seek refuge with You from the evil of what I have done, and from the evil of what I have not done yet.)'" (Using translation from Nasāʾī 5523)  

أَنَّهُ سَأَلَ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ مَا كَانَ أَكْثَرَ مَا كَانَ يَدْعُو بِهِ رَسُولُ اللهِ ﷺ قَبْلَ مَوْتِهِ؟ قَالَتْ كَانَ أَكْثَرَ مَا كَانَ يَدْعُو بِهِ «اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ شَرِّ مَا عَمِلْتُ وَمِنْ سَوْءِ مَا لَمْ أَعْمَلْ»  

"I asked 'Aishah, what was the supplication that the Prophet [SAW] said the most? She said: 'The supplication that he said the most was: Allahumma, inni a'udhu bika min sharri ma 'amiltu wa min sharri ma lam a'mal ba'd (O Allah, I seek refuge with You from the evil of what I have done, and from the evil of what I have not done yet.)'" (Using translation from Nasāʾī 5524)  

سُئِلَتْ عَائِشَةُ مَا كَانَ أَكْثَرَ مَا كَانَ يَدْعُو بِهِ النَّبِيُّ ﷺ؟ فَقَالَتْ كَانَ أَكْثَرَ دُعَائِهِ أَنْ يَقُولُ «اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ شَرِّ مَا عَمِلْتُ وَمِنْ شَرِّ مَا لَمْ أَعْمَلْ بَعْدُ»  

"He would say: 'O Allah, I seek refuge in You from the evil of what I have done, and from the evil of what I have not done.'" (Using translation from Abū Dāʾūd 1550)   

سَأَلْتُ أُمَّ الْمُؤْمِنِينَ عَائِشَةَ بِمَ كَانَ رَسُولُ اللهِ ﷺ يَدْعُو قَالَتْ كَانَ يَقُولُ «أَعُوذُ مِنْ شَرِّ مَا عَمِلْتُ وَمِنْ يَعْنِي مِنْ شَرِّ مَا لَمْ أَعْمَلْ»  

"The Messenger of Allah [SAW] used to say: 'Allahumma, inni a'udhu bika min sharri ma 'amiltu wa min sharri ma lam a'mal ba'd (O Allah, I seek refuge with You from the evil of what I have done and from the evil of what I have not done yet.)'" (Using translation from Nasāʾī 5526)  

كَانَ رَسُولُ اللهِ ﷺ يَقُولُ «اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ شَرِّ مَا عَمِلْتُ وَمِنْ شَرِّ مَا لَمْ أَعْمَلْ»
