I heard Messenger of Allah ﷺ 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. (Using translation from Muslim 2708a)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ نَزَلَ مَنْزِلًا ثُمَّ قَالَ أَعُوذُ بِكَلِمَاتِ اللهِ التَّامَّاتِ مِنْ شَرِّ مَا خَلَقَ لَمْ يَضُرُّهُ شَيْءٌ حَتَّى يَرْتَحِلَ مِنْ مَنْزِلِهِ ذَلِكَ [208] خَالَفَهُ ابْنُ عَجْلَانَ  

[Machine] The Messenger of Allah ﷺ said: "If one of you enters a house and says, 'I seek refuge in the words of Allah from the evil of what He has created,' nothing harmful will come to him in that house until he leaves."  

قَالَ رَسُولُ اللهِ ﷺ لَوْ أَنَّ أَحَدَكُمْ إِذَا نَزَلَ مَنْزِلًا قَالَ أَعُوذُ بِكَلِمَاتِ اللهِ مِنْ شَرِّ مَا خَلَقَ لَمْ يَضُرُّهُ فِي ذَلِكَ الْمَنْزِلِ شَيْءٌ حَتَّى يَرْتَحِلَ مِنْهُ 10320 أَخْبَرَنَا عَبْدُ الْحَمِيدِ بْنُ مُحَمَّدٍ حَدَّثَنَا مَخْلَدٌ حَدَّثَنَا سُفْيَانُ عَنِ ابْنِ عَجْلَانَ عَنْ يَعْقُوبَ بْنِ عَبْدِ اللهِ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ قَالَ قَالَ رَسُولُ اللهِ ﷺ نَحْوَهُ  

[Machine] On the authority of Sulaiman bin Yasir and Busyr bin Sa'id, they said: A man came to the Messenger of Allah ﷺ and said, "I was stung by a scorpion." So the Messenger of Allah ﷺ said to him, "If only you had said, when you reached the evening, 'I seek refuge in the perfect words of Allah from the evil of what He has created,' it would not have harmed you."  

عَنْ سُلَيْمَانَ بْنِ يَسَارٍ وَبُسْرِ بْنِ سَعِيدٍ قَالَا جَاءَ رَجُلٌ إِلَى رَسُولِ اللهِ ﷺ فَقَالَ لَدَغَتْنِي عَقْرَبٌ؟ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ أَمَا لَوْ أَنْ قُلْتَ حِينَ أَمْسَيْتَ أَعُوذُ بِكَلِمَاتِ اللهِ التَّامَّةِ مِنْ شَرِّ مَا خَلَقَ لَمْ يَضُرَّكَ
