Sahih Muslim Book 35, Hadith Number 6541.
Chapter : Seeking of refuge in Allah from the evil of destiny and from the severity of calamity.
Khaula bint Hakim Sulamiyya reported: I heard Allah’s Messenger (may peace be upon him) as saying: When anyone lands at a place, and then says: “I seek refuge in the Perfect Word of Allah from the evil of what He has created,” nothing would harm him until he marches from that stopping place.
