It was narrated that Farwah bin Nawfal said:"I asked 'Aishah: 'Tell me of something that the Messenger of Allah [SAW] used to say in his supplication.' She said: '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)
