Hadith 2715
Sayyidah Khawlah bint Hakim (may Allah be pleased with her) said: The Messenger of Allah (peace and blessings be upon him) said: "When anyone stops at a place (during a journey) and says «أَعُوْذُ بِكَلِمَاتِ اللّٰهِ التَّامَّاتِ مِنْ شَرِّ مَا خَلَقَ», then nothing from that place will harm him until he departs from it."
Translation of the supplication: I seek refuge in the perfect words of Allah from the evil of what He has created.
