"I said to 'Aishah: 'Tell me of a supplication that the Messenger of Allah [SAW] used to say.' She said: 'He 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 in You from the evil of what I have done and from the evil of what I have not done.)'" (Using translation from Nasāʾī 5528)
قُلْتُ لِعَائِشَةَ أَخْبِرِينِي بِدُعَاءٍ كَانَ يَدْعُو بِهِ رَسُولُ اللهِ ﷺ قَالَتْ كَانَ يُكْثِرُ أَنْ يَقُولَ اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ شَرِّ مَا عَمِلْتُ وَمَنْ شَرِّ مَا لَمْ أَعْمَلْ
