What were some of the last words Prophet Muhammad (saw) said before he went to bed each night?
 Narrated Abu Dharr:                     When the Prophet went to bed at night, he used to say: "Bismika namutu wa nahya." And when he got up in the morning, he used to say, "Al hamdu li l-lahi al-ladhi ahyana ba'da ma amatana, wa ilaihi-nnushur."
