When you go to bed during night, you should say:" O Allah, I surrender myself to Thee and entrust my affair to Thee, with hope in Thee and fear of Thee. There is no resort and no deliverer (from hardship but Thou). I affirm my faith in the Book which Thou revealed and in the Messengers whom Thou sent." If you die in this state you would die on Fitra, and Ibn Bashshdr did not make a mention of" night" in this hadith.  

أَنَّ رَسُولَ اللَّهِ ﷺ أَمَرَ رَجُلاً إِذَا أَخَذَ مَضْجَعَهُ مِنَ اللَّيْلِ أَنْ يَقُولَ اللَّهُمَّ أَسْلَمْتُ نَفْسِي إِلَيْكَ وَوَجَّهْتُ وَجْهِي إِلَيْكَ وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ وَفَوَّضْتُ أَمْرِي إِلَيْكَ رَغْبَةً وَرَهْبَةً إِلَيْكَ لاَ مَلْجَأَ وَلاَ مَنْجَا مِنْكَ إِلاَّ إِلَيْكَ آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ وَبِرَسُولِكَ الَّذِي أَرْسَلْتَ فَإِنْ مَاتَ مَاتَ عَلَى الْفِطْرَةِ وَلَمْ يَذْكُرِ ابْنُ بَشَّارٍ فِي حَدِيثِهِ مِنَ اللَّيْلِ  

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)   

أَنَّ رَسُولَ اللهِ ﷺ أَمَرَ رَجُلًا مِنَ الْأَنْصَارِ أَنْ يَقُولَ إِذَا أَخَذَ مَضْجَعَهُ اللهُمَّ أَسْلَمْتُ نَفْسِي إِلَيْكَ وَوَجَّهْتُ وَجْهِي إِلَيْكَ وَفَوَّضْتُ أَمْرِي إِلَيْكَ وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ رَغْبَةً وَرَهْبَةً إِلَيْكَ لَا مَلْجَأَ وَلَا مَنْجَا مِنْكَ إِلَّا إِلَيْكَ آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ وَنَبِيِّكَ الَّذِي أَرْسَلْتَ فَإِنْ مَاتَ مَاتَ عَلَى الْفِطْرَةِ
