It was narrated that Farwah bin Nawfal said:"I asked 'Aishah about a supplication that the Messenger of Allah (saas) used to say. She said that he used to say: 'Allahumma inni a'udhu bika min sharri ma 'amiltu, wa min sharri ma lam a'mal (O Allah, I seek refuge with You from the evil of that which I have done and the evil of that which I have not done)
