The Messenger of Allah ﷺ sued to teach them the following words in the case of alarm: I seek refuge in Allah's perfect words from His anger, the evil of His servants, the evil suggestions of the devils and their presence. Abdullah ibn Amr used to teach them to those of his children who had reached puberty, and he wrote them down (on some material) and hung on the child who had not reached puberty.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُعَلِّمُهُمْ مِنَ الْفَزَعِ كَلِمَاتٍ أَعُوذُ بِكَلِمَاتِ اللَّهِ التَّامَّةِ مِنْ غَضَبِهِ وَشَرِّ عِبَادِهِ وَمِنْ هَمَزَاتِ الشَّيَاطِينِ وَأَنْ يَحْضُرُونِ وَكَانَ عَبْدُ اللَّهِ بْنُ عَمْرٍو يُعَلِّمُهُنَّ مَنْ عَقَلَ مِنْ بَنِيهِ وَمَنْ لَمْ يَعْقِلْ كَتَبَهُ فَأَعْلَقَهُ عَلَيْهِ  

[Machine] He said, "O Messenger of Allah, I feel loneliness." He replied, "When you go to your bed, say, 'I seek refuge in the perfect words of Allah from His anger and punishment, and from the evil of His servants, and from the whispers of the devils, and from their presence.' Indeed, it will not harm you, and it is preferable that nobody comes near you."  

أَنَّهُ قَالَ يَا رَسُولَ اللهِ إِنِّي أَجِدُ وَحْشَةً قَالَ إِذَا أَخَذْتَ مَضْجَعَكَ فَقُلْ أَعُوذُ بِكَلِمَاتِ اللهِ التَّامَّةِ مِنْ غَضَبِهِ وَعِقَابِهِ وَشَرِّ عِبَادِهِ وَمِنْ هَمَزَاتِ الشَّيَاطِينِ وَأَنْ يَحْضُرُونِ فَإِنَّهُ لَا يُضَرُّكَ وَبِالْحَرِيِّ أَنْ لَا يَقْرَبَكَ  

[Machine] He said, "O Messenger of Allah, I feel loneliness." He said, "When you go to your bed, say, 'I seek refuge in the perfect words of Allah from His anger and punishment and from the evil of His servants and the whispers of the devils, and from their presence.' Indeed, it will not harm you, and it is better for you not to approach it."  

أَنَّهُ قَالَ يَا رَسُولَ اللهِ إِنِّي أَجِدُ وَحْشَةً قَالَ فَإِذَا أَخَذْتَ مَضْجَعَكَ فَقُلْ أَعُوذُ بِكَلِمَاتِ اللهِ التَّامَّةُ مِنْ غَضَبِهِ وَعِقَابِهِ وَشَرِّ عِبَادِهِ وَمِنْ هَمَزَاتِ الشَّيَاطِينِ وَأَنْ يَحْضُرُونِ فَإِنَّهُ لَا يَضُرُّكَ وَبِالْحَرِيِّ أَنْ لَا يَقْرَبَكَ  

[Machine] The Messenger of Allah ﷺ used to teach us words to say before sleeping out of fear, "In the name of Allah, I seek refuge in the complete words of Allah from His anger and punishment, from the evil of His slaves, from the whispers of the devils, and that they come near."  

كَانَ رَسُولُ اللهِ ﷺ يُعَلِّمُنَا كَلِمَاتٍ يَقُولُهَا عِنْدَ النَّوْمِ مِنَ الْفَزَعِ «بِاسْمِ اللهِ أَعُوذُ بِكَلِمَاتِ اللهِ التَّامَّاتِ مِنْ غَضَبِهِ وَعِقَابِهِ وَمِنْ شَرِّ عِبَادِهِ وَمِنْ هَمَزَاتِ الشَّيَاطِينِ وَأَنْ يَحْضُرُونِ»  

[Machine] Khalid ibn al-Walid ibn al-Mughirah was a man who would experience fear in his sleep. He mentioned this to the Messenger of Allah ﷺ , and the Prophet ﷺ said to him, "When you lie down to sleep, say, 'In the name of Allah, I seek refuge in the perfect words of Allah from His anger, punishment, the evil of His slaves, and from the whispers of the devils and that they come close.'" So he said it, and that fear went away from him.  

كَانَ خَالِدُ بْنُ الْوَلِيدِ بْنِ الْمُغِيرَةِ رَجُلًا يَفْزَعُ فِي مَنَامِهِ فَذَكَرَ ذَلِكَ لِرَسُولِ اللهِ ﷺ فَقَالَ لَهُ النَّبِيُّ ﷺ إِذَا اضْطَجَعْتَ فَقُلْ بِاسْمِ اللهِ أَعُوذُ بِكَلِمَاتِ اللهِ التَّامَّةِ مِنْ غَضَبِهِ وَعِقَابِهِ وَشَرِّ عِبَادِهِ وَمِنْ هَمَزَاتِ الشَّيَاطِينِ وَأَنْ يَحْضُرُونِ فَقَالَهَا فَذَهَبَ ذَلِكَ عَنْهُ  

"إِذَا فزعَ أحدُكُم في النَّوم فليقلْ: باسْم الله أعوذُ بكلماتِ الله التَّامة مِنْ غضبِه وشرِّ عقابه وشرِّ عبِاده، ومِنْ همزاتِ الشَّياطين وأنْ يحضرون؛ فإِنها لنْ تَضُرَّه".  

"إذا أخذت مضجعك فقل: أعوذ بكلمات الله التَّامَّة من غضبه وعقابيه، وشرَّ عباده، ومن هَمزات الشياطين أن يحضرون، فإنه لا يضُرُّك، وبالحرِيِّ ألا يَضُرَّك".  

"إِذَا اضطجعت فقلْ: بسم الله، أعوذُ بكلمةِ اللهِ التَّامَّةِ منْ غَضَبِه وعِقَابه ومنْ شرِّ عبادِه ومِنْ همزاتِ الشياطينِ وأنْ يحضرون" .
