اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ شَرِّ مَا عَمِلْتُ وَمِنْ شَرِّ مَا لَمْ أَعْمَلْ
Allahumma inni a'udhu bika min sharri ma 'amiltu wa min sharri ma lam a'mal
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.
Protection from two directions: the consequences of what you did (sins committed, hurtful words spoken, bad decisions made) and the consequences of what you didn't do (prayers missed, people not helped, opportunities for good wasted). Omission can be as dangerous as commission. This du'a covers both the sins of action and the sins of inaction.
