The Prophet (ﷺ) said:

اَللَّهُمَّ إِنِّي أَعُوْذُ بِكَ مِنْ شَرِّ نَفْسِيْ وَأَسْأَلُكَ أَنْ تَعْزِمَ لِي عَلَى رُشْدِ أَمْرِيْ

Allahumma inni A‛oodhu bika min sharri nafsi wa ‘as’aluka an ta’zima li ‘alaa rushdi ‘amri

Ya Allah! I seek refuge in You from harm of myself and I ask you for guidence and steadfastness to do right things
