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»
