The Prophet (ﷺ) said to me, "Whenever you go to bed perform ablution like that for the (prayer), lie on your right side and say: Allahumma inni aslamtu wajhî ilaika, wa fauwaḍtu 'Amrî ilaika, wa alja‘tu zahrî ilaika raghbatan wa rahbatan ilaika. La wa manja minka illâ ilaika. Allahumma âmantu bikitâbikal-ladhî anzalta wa bi na-bîyikal-ladhî arsalta, [O Allâh ! 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 Allâh ! I believe in Your Book (the Qur'ân) which You have revealed and in Your Prophet (ﷺ) (Muḥammad whom you have sent]. Then if you die on that very night, you will die with faith (i.e. on the religion of Islâm). Let the aforesaid words be your last utterance (before sleep)." I repeated it before the Prophet (ﷺ) and when I reached Allâhumma âmantu bikitâbikal-ladhi anzalta (O Allâh I believe in Your Book which You have revealed)." I said, "Wa Rasûlika (and Your Messenger (ﷺ)). The Prophet (ﷺ) said, "No, (but say): Wa nabiyikal-ladhî arsalta (Your Prophet (ﷺ) whom You have sent), instead." [1:247-O.B.]
