It is narrated from Hazrat Khawlah (may Allah be pleased with her) that I heard the Prophet (peace and blessings be upon him) say: Whoever halts at a place and recites these words «أَعُوذُ بِكَلِمَاتِ اللَّهِ التَّامَّةِ مِنْ شَرِّ مَا خَلَقَ» , then nothing will harm him until he departs from that place.
