Sunan Ibn Majah 3547

It was narrated from Khawlah bint Hakim that the Prophet (ﷺ) said:“If anyone of you, when he stops to camp (while on a journey), says A’udhu bi kalimatil-lahit-tammati min sharri ma khalaq (I seek refuge in the Perfect Words of Allah from the evil of that which He has created), then nothing will harm him in that place until he moves on.”
