اللَّهُـمَّ أَسْـلَمْتُ نَفْـسِي إِلَـيْكَ، وَفَوَّضْـتُ أَمْـرِي إِلَـيْكَ، وَوَجَّـهْتُ وَجْـهِي إِلَـيْكَ، وَأَلْـجَـاْتُ ظَهْـرِي إِلَـيْكَ، رَغْبَـةً وَرَهْـبَةً إِلَـيْكَ، لاَ مَلْجَـأَ وَلاَ مَنْـجَـا مِنْـكَ إِلاَّ إِلَـيْكَ، آمَنْـتُ بِكِتَـابِكَ الَّـذِي أَنْزَلْـتَ وَبِنَبِـيِّـكَ الَّـذِي أَرْسَلْـتَ.

# Translation
O Allah, I submit my soul unto You, and I entrust my affair unto You, and I turn my face towards You, and I totally rely on You, in hope and fear of You. Verily there is no refuge nor safe haven from You except with You. I believe in Your Book which You have revealed and in Your Prophet whom You have sent.

Before you go to bed perform ablutions as you would for prayer, then lie down on your right side and say [this]. The Prophet (SAW) said: Whoever says this and dies in his sleep, has died in a state of the natural monotheism (Fitrah). Al-Bukhari, cf. Al-Asqalani, Fathul-Bari 11/113, Muslim 4/2081
