حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ، عَنْ حُصَيْنٍ، عَنْ هِلاَلٍ، عَنْ فَرْوَةَ بْنِ نَوْفَلٍ، قَالَ سَأَلْتُ عَائِشَةَ عَنْ دُعَاءٍ، كَانَ يَدْعُو بِهِ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ فَقَالَتْ كَانَ يَقُولُ ‏"‏ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ شَرِّ مَا عَمِلْتُ وَمِنْ شَرِّ مَا لَمْ أَعْمَلْ ‏"‏ ‏.‏

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).'"
