The Prophet said: “When one of you lies down on his right side, then says: ‘O Allah, I have submitted myself to You, and I have turned my face to You, and I lay myself down relying upon You, and I have entrusted my affair to You, there is no refuge [nor escape] from You except to You. I believe in Your Book and Your Messengers (Allāhumma innī aslamtu nafsī ilaika wa wajjahtu wajhī ilaika, wa alja’tu ẓahrī ilaika, wa fawwaḍtu amrī ilaika, lā malja'a [wa lā manjā] minka illā ilaik, ūminu bikitābika wa birusulika)’ – then if he dies that night, he shall enter Paradise.”  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا اضْطَجَعَ أَحَدُكُمْ عَلَى جَنْبِهِ الأَيْمَنِ ثُمَّ قَالَ اللَّهُمَّ إِنِّي أَسْلَمْتُ نَفْسِي إِلَيْكَ وَوَجَّهْتُ وَجْهِي إِلَيْكَ وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ وَفَوَّضْتُ أَمْرِي إِلَيْكَ لاَ مَلْجَأَ وَلاَ مَنْجَا مِنْكَ إِلاَّ إِلَيْكَ أُومِنُ بِكِتَابِكَ وَبِرُسُلِكَ فَإِنْ مَاتَ مِنْ لَيْلَتِهِ دَخَلَ الْجَنَّةَ  

the Prophet (saas) said to a man: "When you go to lay down, or go to your bed, say: Allahumma aslamtu wajhi ilayka, wa al-ja'tu zahri ilayka, wa fawwadtu amri ilayka, raghbatan wa rahbatan ilayka, la malja'a wa la manja'a minka illa ilayka, amantu bi kitabikal-ladhi anzalta, wa nabiyyikal arsalta [O Allah, I have submitted my face (i.e., myself) to You, and I am under Your command (i.e., I depend upon You in all my affairs), and I put my trust in You, hoping for Your reward and fearing Your punishment. There is no fleeing from You and no refuge from You except with You. I believe in Your Book that You have revealed and in Your Prophet whom You have sent).' Then if you die that night, you will die in a state of the Fitrah (nature), and if you wake in the morning you will wake with a great deal of good." (Using translation from Ibn Mājah 3876)   

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا أَوَيْتَ إِلَى فِرَاشِكَ فَتَوَضَّأْ وَنَمْ عَلَى شِقِّكَ الْأَيْمَنِ وَقُلْ اللهُمَّ أَسْلَمْتُ وَجْهِي إِلَيْكَ وَفَوَّضْتُ أَمْرِي إِلَيْكَ وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ رَهْبَةً وَرَغْبَةً إِلَيْكَ لَا مَلْجَأَ وَلَا مَنْجَا مِنْكَ إِلَّا إِلَيْكَ آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ وَبِنَبِيِّكَ الَّذِي أَرْسَلْتَ فَإِنْ مُتَّ مُتَّ عَلَى الْفِطْرَةِ  

The Prophet said: “When one of you lies down on his right side, then says: ‘O Allah, I have submitted myself to You, and I have turned my face to You, and I lay myself down relying upon You, and I have entrusted my affair to You, there is no refuge [nor escape] from You except to You. I believe in Your Book and Your Messengers (Allāhumma innī aslamtu nafsī ilaika wa wajjahtu wajhī ilaika, wa alja’tu ẓahrī ilaika, wa fawwaḍtu amrī ilaika, lā malja'a [wa lā manjā] minka illā ilaik, ūminu bikitābika wa birusulika)’ – then if he dies that night, he shall enter Paradise.” (Using translation from Tirmidhī 3395)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا اضْطَجَعَ أَحَدُكُمْ عَلَى شِقِّهِ الْأَيْمَنِ فَلْيَقُلِ اللهُمَّ إِنِّي أَسْلَمْتُ دِينِي إِلَيْكَ وَوَجَّهْتُ وَجْهِي إِلَيْكَ وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ وَفَوَّضْتُ أَمْرِي إِلَيْكَ لَا مَنْجَى مِنْكَ إِلَّا إِلَيْكَ فَإِنْ مَاتَ مِنْ لَيْلَتِهِ دَخَلَ الْجَنَّةَ زَادَ إِبْرَاهِيمُ فِي حَدِيثِهِ «وَأُؤمِنُ بِكَ وَبِرُسُلِكَ»

"إِذَا اضْطَّجَعَ أحدُكم على جنْبهِ الأيمنِ، ثمَّ قال: اللَّهُمَّ إني أسلمتُ نفسِى إليكَ ووجّهتُ وجْهى إليكَ، وألجأتُ ظهْرِى إليكَ وفوَّضتُ أمْرى إليك، لا ملجأ مِنْك إلا إليكَ أوْمِنُ بكتابِكَ وبرسولِكَ، فإنْ مات منْ ليلتِه دخل الجنةَ".
