Narrated Al-Bara bin `Azib: Allah's Apostle said to me, "When you want to go to bed, perform ablution as you do for prayer, then lie down on your right side and say: 'Allahumma aslamtu wajhi ilaika, wa fauwadtu `Amri ilaika wa aljatu zahri ilaika, raghbatan wa rahbatan ilaika, lamalja'a wa la manna mink a ill a ilaika. Amantu bikitabi kalladhi anzalta wa bi nabiyyikal-ladhi arsalta'. If you should die then (after reciting this) you will die on the religion of Islam (i.e., as a Muslim); so let these words be the last you say (before going to bed)" While I was memorizing it, I said, "Wa birasiulikal-ladhi arsalta (in Your Apostle whom You have sent).' The Prophet said, "No, but say: Wa binabiyyi-kalladhi arsalta (in Your Prophet whom You have sent).

Narrated Al-Bara 'bin `Azib: The Prophet said to me, "Whenever you go to bed perform ablution like that for the prayer, lie or your right side and say, "Allahumma aslamtu wajhi ilaika, wa fauwadtu `Amri ilaika, wa alja'tu Zahri ilaika raghbatan wa rahbatan ilaika. La Malja'a wa la manja minka illa ilaika. Allahumma amantu bikitabika-l-ladhi anzalta wa bina-biyika-l ladhi arsalta" (O Allah! I surrender to You and entrust all my affairs to You and depend upon You for Your Blessings both with hope and fear of You. There is no fleeing from You, and there is no place of protection and safety except with You O Allah! I believe in Your Book (the Qur'an) which You have revealed and in Your Prophet (Muhammad) whom You have sent). Then if you die on that very night, you will die with faith (i.e. or the religion of Islam). Let the aforesaid words be your last utterance (before sleep)." I repeated it before the Prophet and when I reached "Allahumma amantu bikitabika-l-ladhi anzalta (O Allah I believe in Your Book which You have revealed)." I said, "Wa-rasulika (and your Apostle)." The Prophet said, "No, (but say): 'Wanabiyika-l-ladhi arsalta (Your Prophet whom You have sent), instead."

Narrated Al-Bara bin `Azib: That the Prophet advised a man, saying, "If you intend to lie down (i.e. go to bed), say, 'Allahumma aslamtu nafsi ilaika wa fauwadtu `Amri ilaika, wa wajjahtu wajhi ilaika wa alja'tu zahri ilaika, reghbatan wa rahbatan ilaika. La malja'a wa la manja minka illa ilaika. Amantu bikitabikal-ladhi anzalta; wa nabiyyikalladhi arsalta.' And if you should die then (after reciting this before going to bed) you will die on the religion of Islam"

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, raghbatan wa rahbatan ilaika. La Malja'a wa la manja minka illa ilaika. Amantu bikitabika al-ladhi anzalta 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).

Narrated Al-Bara' bin `Azib: Allah's Apostle said, "O so-and-so, whenever you go to your bed (for sleeping) say, 'O Allah! I have surrendered myself over to you and have turned my face towards You, and leave all my affairs to You and depend on You and put my trust in You expecting Your reward and fearing Your punishment. There is neither fleeing from You nor refuge but with You. I believe in the Book (Qur'an) which You have revealed and in Your Prophet (Muhammad) whom You have sent.' If you then die on that night, then you will die as a Muslim, and if you wake alive in the morning then you will receive the reward." (See Hadith No. 323, Vol. 8)
