عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَنْ قَالَ إِذَا أَمْسَى ثَلَاثَ مَرَّاتٍ أَعُوذُ بِكَلِمَاتِ اللَّهِ التَّامَّاتِ مِنْ شَرِّ مَا خَلَقَ لَمْ تَضُرَّهُ حُمَةٌ تِلْكَ اللَّيْلَةَ قَالَ فَكَانَ أَهْلُنَا قَدْ تَعَلَّمُوهَا فَكَانُوا يَقُولُونَهَا فَلُدِغَتْ جَارِيَةٌ مِنْهُمْ فَلَمْ تَجِدْ لَهَا وَجَعًا
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: Whoever recites this supplication three times in the evening: "I seek refuge in the perfect words of Allah from the evil of what He has created," no poison will harm him that night. The narrator says: Our families learned this supplication and used to recite it; once a girl was bitten by something, but she did not suffer any harm from it.
