Volume 8, Book 75, Number 327:
Narrated Al-Bara’ bin ‘Azib:
When Allah’s Apostle 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 Amri ilaika, wa alja’tu zahri ilaika, ragh –
batan wa rahbatan ilaika. La Malja’a wa la manja minka illa ilaika. Amantu bikitabika al-ladhi anza –
lta wa nabiyyika al-ladhi arsalta! Allah’s Apostle said, “Whoever recites these words (before going to
bed) and dies the same night, he will die on the Islamic religion (as a Muslim).”
