(63) باب التَّعَوُّذِ فِي الصَّلاَةِ
It was narrated that Farwah bin Nawfal said:
"I said to 'Aishah: 'Tell me of a supplication that the Messenger of Allah (ﷺ) used to say in his prayer.' She said: 'Yes. The Messenger of Allah (ﷺ) used to say: Allahumma inni author 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.)'" (ES)
