It was narrated from Bara' bin 'Azib that the Prophet(saw) said to a man: "When you go to lay down, or go to your bed, say: [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." (Sahih)
