The Prophet ﷺ said, "When anyone of you go to bed, he should shake out his bed with the inside of his waist sheet, for he does not know what has come on to it after him, and then he should say: 'Bismika Rabbi Wadaʿtu Janbi wa bika arfa'uhu, In amsakta nafsi farhamha wa in arsaltaha fahfazha bima tahfazu bihi ibadakas-salihin."  

النَّبِيُّ ﷺ إِذَا أَوَى أَحَدُكُمْ إِلَى فِرَاشِهِ فَلْيَنْفُضْ فِرَاشَهُ بِدَاخِلَةِ إِزَارِهِ فَإِنَّهُ لاَ يَدْرِي مَا خَلَفَهُ عَلَيْهِ ثُمَّ يَقُولُ بِاسْمِكَ رَبِّ وَضَعْتُ جَنْبِي وَبِكَ أَرْفَعُهُ إِنْ أَمْسَكْتَ نَفْسِي فَارْحَمْهَا وَإِنْ أَرْسَلْتَهَا فَاحْفَظْهَا بِمَا تَحْفَظُ بِهِ عِبَادَكَ الصَّالِحِينَ  

The Prophet ﷺ said, "When anyone of you goes to bed, he should dust it off thrice with the edge of his garment, and say: Bismika Rabbi Wadaʿtu janbi, wa bika arfa'hu. In amsakta nafsi faghfir laha, wa in arsaltaha fahfazha bima tahfaz bihi 'ibadaka-s-salihin."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا جَاءَ أَحَدُكُمْ فِرَاشَهُ فَلْيَنْفُضْهُ بِصَنِفَةِ ثَوْبِهِ ثَلاَثَ مَرَّاتٍ وَلْيَقُلْ بِاسْمِكَ رَبِّ وَضَعْتُ جَنْبِي وَبِكَ أَرْفَعُهُ إِنْ أَمْسَكْتَ نَفْسِي فَاغْفِرْ لَهَا وَإِنْ أَرْسَلْتَهَا فَاحْفَظْهَا بِمَا تَحْفَظُ بِهِ عِبَادَكَ الصَّالِحِينَ  

Whenever the Prophet ﷺ went to bed every night, he used to cup his hands together and blow over it after reciting Surat Al-Ikhlas, Surat Al-Falaq and Surat An-Nas, and then rub his hands over whatever parts of his body he was able to rub, starting with his head, face and front of his body. He used to do that three times.  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا أَوَى إِلَى فِرَاشِهِ كُلَّ لَيْلَةٍ جَمَعَ كَفَّيْهِ ثُمَّ نَفَثَ فِيهِمَا فَقَرَأَ فِيهِمَا {قُلْ هُوَ اللَّهُ أَحَدٌ} وَ{قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ} وَ{قُلْ أَعُوذُ بِرَبِّ النَّاسِ} ثُمَّ يَمْسَحُ بِهِمَا مَا اسْتَطَاعَ مِنْ جَسَدِهِ يَبْدَأُ بِهِمَا عَلَى رَأْسِهِ وَوَجْهِهِ وَمَا أَقْبَلَ مِنْ جَسَدِهِ يَفْعَلُ ذَلِكَ ثَلاَثَ مَرَّاتٍ  

The Prophet ﷺ said to me, "Whenever you go to bed perform ablution like that for the prayer, lie or your right side and say, "Allahumma aslamtu wajhi ilaika, wa fauwadtu ʿAmri ilaika, wa alja'tu Zahri ilaika raghbatan wa rahbatan ilaika. La Malja'a wa la manja minka illa ilaika. Allahumma amantu bikitabika-l-ladhi anzalta wa bina-biyika-l ladhi arsalta" (O Allah! I surrender to You and entrust all my affairs to You and depend upon You for Your Blessings both with hope and fear of You. There is no fleeing from You, and there is no place of protection and safety except with You O Allah! I believe in Your Book (the Qur'an) which You have revealed and in Your Prophet (Muhammad) whom You have sent). Then if you die on that very night, you will die with faith (i.e. or the religion of Islam). Let the aforesaid words be your last utterance (before sleep)." I repeated it before the Prophet ﷺ and when I reached "Allahumma amantu bikitabika-l-ladhi anzalta (O Allah I believe in Your Book which You have revealed)." I said, "Wa-rasulika (and your Apostle)." The Prophet ﷺ said, "No, (but say): 'Wanabiyika-l-ladhi arsalta (Your Prophet whom You have sent), instead."  

قَالَ النَّبِيُّ ﷺ إِذَا أَتَيْتَ مَضْجَعَكَ فَتَوَضَّأْ وُضُوءَكَ لِلصَّلاَةِ ثُمَّ اضْطَجِعْ عَلَى شِقِّكَ الأَيْمَنِ ثُمَّ قُلِ اللَّهُمَّ أَسْلَمْتُ وَجْهِي إِلَيْكَ وَفَوَّضْتُ أَمْرِي إِلَيْكَ وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ رَغْبَةً وَرَهْبَةً إِلَيْكَ لاَ مَلْجَأَ وَلاَ مَنْجَا مِنْكَ إِلاَّ إِلَيْكَ اللَّهُمَّ آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ وَبِنَبِيِّكَ الَّذِي أَرْسَلْتَ فَإِنْ مُتَّ مِنْ لَيْلَتِكَ فَأَنْتَ عَلَى الْفِطْرَةِ وَاجْعَلْهُنَّ آخِرَ مَا تَتَكَلَّمُ بِهِ قَالَ فَرَدَّدْتُهَا عَلَى النَّبِيِّ ﷺ فَلَمَّا بَلَغْتُ اللَّهُمَّ آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ قُلْتُ وَرَسُولِكَ قَالَ لاَ وَنَبِيِّكَ الَّذِي أَرْسَلْتَ  

Messenger of Allah ﷺ said to me, "When you want to go to bed, perform ablution as you do for prayer, then lie down on your right side and say: 'Allahumma aslamtu wajhi ilaika, wa fawwadtu 'amri ilaika wa alja'tu dhahri ilaika, raghbatan wa rahbatan ilaika, la malja'a wa la manja minka illa ilaika. Amantu bikitabik al-ladhi anzalta wa binabiyyika al-ladhi arsalta'. If you should die then (after reciting this) you will die on the religion of Islam (i.e., as a Muslim); so let these words be the last you say (before going to bed)" While I was memorizing it, I said, "Wa birasulika al-ladhi arsalta (in Your Apostle whom You have sent).' The Prophet ﷺ said, "No, but say: Wa binabiyyika al-ladhi arsalta (in Your Prophet whom You have sent).  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَتَيْتَ مَضْجَعَكَ فَتَوَضَّأْ وَضُوءَكَ لِلصَّلاَةِ ثُمَّ اضْطَجِعْ عَلَى شِقِّكَ الأَيْمَنِ وَقُلِ اللَّهُمَّ أَسْلَمْتُ وَجْهِي إِلَيْكَ وَفَوَّضْتُ أَمْرِي إِلَيْكَ وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ رَغْبَةً وَرَهْبَةً إِلَيْكَ لاَ مَلْجَأَ وَلاَ مَنْجَا مِنْكَ إِلاَّ إِلَيْكَ آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ وَبِنَبِيِّكَ الَّذِي أَرْسَلْتَ فَإِنْ مُتَّ مُتَّ عَلَى الْفِطْرَةِ فَاجْعَلْهُنَّ آخِرَ مَا تَقُولُ فَقُلْتُ أَسْتَذْكِرُهُنَّ وَبِرَسُولِكَ الَّذِي أَرْسَلْتَ قَالَ لاَ وَبِنَبِيِّكَ الَّذِي أَرْسَلْتَ  

That the Prophet ﷺ advised a man, saying, "If you intend to lie down (i.e. go to bed), say, 'Allahumma aslamtu nafsi ilaika wa fauwadtu ʿAmri ilaika, wa wajjahtu wajhi ilaika wa alja'tu zahri ilaika, reghbatan wa rahbatan ilaika. La malja'a wa la manja minka illa ilaika. Amantu bikitabikal-ladhi anzalta; wa nabiyyikalladhi arsalta.' And if you should die then (after reciting this before going to bed) you will die on the religion of Islam"  

أَنَّ النَّبِيَّ ﷺ أَمَرَ رَجُلاً وَحَدَّثَنَا آدَمُ حَدَّثَنَا شُعْبَةُ حَدَّثَنَا أَبُو إِسْحَاقَ الْهَمْدَانِيُّ عَنِ الْبَرَاءِ بْنِ عَازِبٍ أَنَّ النَّبِيَّ ﷺ أَوْصَى رَجُلاً فَقَالَ إِذَا أَرَدْتَ مَضْجَعَكَ فَقُلِ اللَّهُمَّ أَسْلَمْتُ نَفْسِي إِلَيْكَ وَفَوَّضْتُ أَمْرِي إِلَيْكَ وَوَجَّهْتُ وَجْهِي إِلَيْكَ وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ رَغْبَةً وَرَهْبَةً إِلَيْكَ لاَ مَلْجَأَ وَلاَ مَنْجَا مِنْكَ إِلاَّ إِلَيْكَ آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ وَبِنَبِيِّكَ الَّذِي أَرْسَلْتَ فَإِنْ مُتَّ مُتَّ عَلَى الْفِطْرَةِ  

When Messenger of Allah ﷺ went to bed, he used to sleep on his right side and then say, "All-ahumma aslamtu nafsi ilaika, wa wajjahtu wajhi ilaika, wa fauwadtu ʿAmri ilaika, wa alja'tu zahri ilaika, raghbatan wa rahbatan ilaika. La Malja'a wa la manja minka illa ilaika. Amantu bikitabika al-ladhi anzalta wa nabiyyika al-ladhi arsalta! Messenger of Allah ﷺ said, "Whoever recites these words (before going to bed) and dies the same night, he will die on the Islamic religion (as a Muslim).  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا أَوَى إِلَى فِرَاشِهِ نَامَ عَلَى شِقِّهِ الأَيْمَنِ ثُمَّ قَالَ اللَّهُمَّ أَسْلَمْتُ نَفْسِي إِلَيْكَ وَوَجَّهْتُ وَجْهِي إِلَيْكَ وَفَوَّضْتُ أَمْرِي إِلَيْكَ وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ رَغْبَةً وَرَهْبَةً إِلَيْكَ لاَ مَلْجَأَ وَلاَ مَنْجَا مِنْكَ إِلاَّ إِلَيْكَ آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ وَنَبِيِّكَ الَّذِي أَرْسَلْتَ وَقَالَ رَسُولُ اللَّهِ ﷺ مَنْ قَالَهُنَّ ثُمَّ مَاتَ تَحْتَ لَيْلَتِهِ مَاتَ عَلَى الْفِطْرَةِ {اسْتَرْهَبُوهُمْ} مِنَ الرَّهْبَةِ مَلَكُوتٌ مُلْكٌ مَثَلُ رَهَبُوتٌ خَيْرٌ مِنْ رَحَمُوتٍ تَقُولُ تَرْهَبُ خَيْرٌ مِنْ أَنْ تَرْحَمَ  

Messenger of Allah ﷺ said, "O so-and-so, whenever you go to your bed (for sleeping) say, 'O Allah! I have surrendered myself over to you and have turned my face towards You, and leave all my affairs to You and depend on You and put my trust in You expecting Your reward and fearing Your punishment. There is neither fleeing from You nor refuge but with You. I believe in the Book (Qur'an) which You have revealed and in Your Prophet (Muhammad) whom You have sent.' If you then die on that night, then you will die as a Muslim, and if you wake alive in the morning then you will receive the reward." (See Hadith No. 323, Vol. 8)  

قَالَ رَسُولُ اللَّهِ ﷺ يَا فُلاَنُ إِذَا أَوَيْتَ إِلَى فِرَاشِكَ فَقُلِ اللَّهُمَّ أَسْلَمْتُ نَفْسِي إِلَيْكَ وَوَجَّهْتُ وَجْهِي إِلَيْكَ وَفَوَّضْتُ أَمْرِي إِلَيْكَ وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ رَغْبَةً وَرَهْبَةً إِلَيْكَ لاَ مَلْجَأَ وَلاَ مَنْجَا مِنْكَ إِلاَّ إِلَيْكَ آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ وَبِنَبِيِّكَ الَّذِي أَرْسَلْتَ فَإِنَّكَ إِنْ مُتَّ فِي لَيْلَتِكَ مُتَّ عَلَى الْفِطْرَةِ وَإِنْ أَصْبَحْتَ أَصَبْتَ أَجْرًا  

When you go to bed, say:" Praise is due to Allah Who fed us, provided us drink, sufficed us and provided us with shelter, for many a people there is none to suffice and none to provide shelter."  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا أَوَى إِلَى فِرَاشِهِ قَالَ الْحَمْدُ لِلَّهِ الَّذِي أَطْعَمَنَا وَسَقَانَا وَكَفَانَا وَآوَانَا فَكَمْ مِمَّنْ لاَ كَافِيَ لَهُ وَلاَ مُئْوِيَ  

When the Messenger of Allah ﷺ wanted to go to sleep, he put his right hand under his cheek and would then say three times: O Allah, guard me from Thy punishment on the day when Thou raisest up Thy servants.  

عَنْ حَفْصَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا أَرَادَ أَنْ يَرْقُدَ وَضَعَ يَدَهُ الْيُمْنَى تَحْتَ خَدِّهِ ثُمَّ يَقُولُ اللَّهُمَّ قِنِي عَذَابَكَ يَوْمَ تَبْعَثُ عِبَادَكَ ثَلاَثَ مِرَارٍ
