(16) باب مَا يَقُولُ إِذَا أَصْبَحَ
Narrated Hudhaifa:
Whenever the Prophet (ﷺ) intended to go to bed, he would recite: "Bismika Allahumma amutu wa ahya (With Your name, O Allah, I die and I live)." And when he woke up from his sleep, he would say: "Al-hamdu lil-lahil-ladhi ahyana ba'da ma amatana; wa ilaihi an-nushur (All the Praises are for Allah Who has made us alive after He made us die (sleep) and unto Him is the Resurrection). "
