Section : What a Traveller Should Say on Stopping at a Place.
Khaulah, daughter of Hakim As-Sallammiya, reported that the Prophet, peace be upon him, said, “If anyone stops at a place and then says, ‘I seek refuge with all the perfect words of Allah from the evil of his creatures,’ nothing will harm him until he departs from that place.” (Reported by the Group except Bukhari and Abu Daw’ud)
