عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَجُلًا مِنْ أَسْلَمَ قَالَ لَمَّا نِمْتُ هَذِهِ اللَّيْلَةَ لَدَغَتْنِي عَقْرَبٌ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَمَا لَوْ قُلْتَ حِينَ أَمْسَيْتَ أَعُوذُ بِكَلِمَاتِ اللَّهِ التَّامَّاتِ مِنْ شَرِّ مَا خَلَقَ لَمْ يَضُرَّكَ
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that a man from Banu Aslam said: When I slept last night, a scorpion stung me. The Messenger of Allah, peace and blessings be upon him, said: If you had said in 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.
