It was narrated from Umm Salamah that whenever he left his house, the Prophet ﷺ would say:
“Allahumma inni a’udhu bika an adilla aw azilla, aw azlima aw uzlama, aw ajhala aw yujhala ‘alayya (O Allah, I seek refuge with You from going astray or stumbling, from wronging others or being wronged, and from behaving or being treated in an ignorant manner).”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبِيدَةُ بْنُ حُمَيْدٍ، عَنْ مَنْصُورٍ، عَنِ الشَّعْبِيِّ، عَنْ أُمِّ سَلَمَةَ، . أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا خَرَجَ مِنْ مَنْزِلِهِ قَالَ " اللَّهُمَّ إِنِّي أَعُوذُ بِكَ أَنْ أَضِلَّ أَوْ أَزِلَّ أَوْ أَظْلِمَ أَوْ أُظْلَمَ أَوْ أَجْهَلَ أَوْ يُجْهَلَ عَلَىَّ " .
