أَخْبَرَنِي مُحَمَّدُ بْنُ قُدَامَةَ، عَنْ جَرِيرٍ، عَنْ مَنْصُورٍ، عَنْ هِلاَلِ بْنِ يِسَافٍ، عَنْ فَرْوَةَ بْنِ نَوْفَلٍ، قَالَ سَأَلْتُ أُمَّ الْمُؤْمِنِينَ عَائِشَةَ عَمَّا كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَدْعُو قَالَتْ كَانَ يَقُولُ " أَعُوذُ بِكَ مِنْ شَرِّ مَا عَمِلْتُ وَمِنْ شَرِّ مَا لَمْ أَعْمَلْ " .
It was narrated that Farwah bin Nawfal said: "I asked the Mother of the Believers 'Aishah about what the Messenger of Allah [SAW] used to say in his supplication. She said: 'He used to say: A'udhu bika min sharri ma 'amiltu wa min sharri ma lam a'mal ba'd (I seek refuge with You from the evil of what I have done and the evil of what I have not done yet.)'"
