What was the dua that the Prophet Muhammad (saw) recited when he went to bed and when he woke up?
 Narrated Juhaifa:                     When the Prophet went to bed, he used to say, "Allhumma bismika ahya wa amut." And when he got Up in the mornings he used to say, "Al hamdu li l-lahi al-ladhi ahyana ba'da ma amatana wa ilaihi-nnushur."
