It was narrated from Umm Salamah that:
When the Prophet [SAW] 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 wronging (others) or being wronged, and from behaving or being treated in an ignorant manner.)
