Khaulah bint Hakim (May Allah be pleased with her) reported:
I heard the Messenger of Allah (ﷺ) saying, "Whosoever alights somewhere and says: 'A'udhu bikalimat-illahit-tammati min sharri ma khalaqa (I seek refuge with the Perfect Words of Allah from the evil of what He has created),' nothing will harm him until he leaves that place."[Muslim].
