What are the two phrases that Prophet Muhammad (peace be upon him) said when he went to sleep and when he awoke?
 Narrated Hudhaifa:                     When the Prophet went to bed, he would say: "Bismika amutu wa ahya." and when he got up he would say:" Al-hamdu li l-lahil-ladhi ahyana ba'da ma amatana wa ilaihin-nushur."
