[Machine] A man from the companions of the Prophet ﷺ was bitten, and it affected him as Allah willed. This news reached the Prophet ﷺ, who said, “Indeed, if he had said 'I seek refuge in the perfect words of Allah from the evil of what He has created,' it would not have harmed him (the man).”  

الكبرى للنسائي:١٠٣٤٩ – قَرَأْتُ عَلَى مُحَمَّدِ بْنِ سُلَيْمَانَ لُوَيْنٌ عَنْ حَمَّادِ بْنِ زَيْدٍ عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ

أَنَّ رَجُلًا مِنْ أَصْحَابِ النَّبِيِّ ﷺ لُدِغَ فَبَلَغَ مِنْهُ مَا شَاءَ اللهُ فَبَلَغَ ذَلِكَ النَّبِيَّ ﷺ فَقَالَ أَمَا إِنَّهُ لَوْ قَالَ أَعُوذُ بِكَلِمَاتِ اللهِ التَّامَّةِ مِنْ شَرِّ مَا خَلَقَ لَمْ يَضُرُّهُ

“If anyone of you, when he stops to camp (while on a journey), says A’udhu bi kalimatil-lahit-tammati min sharri ma khalaq (I seek refuge in the Perfect Words of Allah from the evil of that which He has created), then nothing will harm him in that place until he moves on.”  

ابن ماجة:٣٥٤٧ – حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا عَفَّانُ حَدَّثَنَا وُهَيْبٌ حَدَّثَنَا مُحَمَّدُ بْنُ عَجْلاَنَ عَنْ يَعْقُوبَ بْنِ عَبْدِ اللَّهِ بْنِ الأَشَجِّ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ عَنْ سَعْدِ بْنِ مَالِكٍ عَنْ خَوْلَةَ بِنْتِ حَكِيمٍ

أَنَّ النَّبِيَّ ﷺ قَالَ لَوْ أَنَّ أَحَدَكُمْ إِذَا نَزَلَ مَنْزِلاً قَالَ أَعُوذُ بِكَلِمَاتِ اللَّهِ التَّامَّةِ مِنْ شَرِّ مَا خَلَقَ لَمْ يَضُرَّهُ فِي ذَلِكَ الْمَنْزِلِ شَىْءٌ حَتَّى يَرْتَحِلَ مِنْهُ
