أَخْبَرَنِي مُحَمَّدُ بْنُ قُدَامَةَ، قَالَ حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنِ الشَّعْبِيِّ، عَنْ أُمِّ سَلَمَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ إِذَا خَرَجَ مِنْ بَيْتِهِ قَالَ ‏
"‏ بِسْمِ اللَّهِ رَبِّ أَعُوذُ بِكَ مِنْ أَنْ أَزِلَّ أَوْ أَضِلَّ أَوْ أَظْلِمَ أَوْ أُظْلَمَ أَوْ أَجْهَلَ أَوْ يُجْهَلَ عَلَىَّ ‏"‏ ‏.‏

It was narrated from Umm Salamah that : When the Prophet went out of his house, he said: "Bismillahi Rabbi! A'udhu bika min an azilla aw adilla aw azlima aw uzlama, aw ajhala aw yujhala 'alayya (In the name of Allah, my Lord, I seek refuge in You from falling into error or going astray, or wrongdoing (others) or being wronged, and from behaving or being treated in an ignorant manner.)"
