Sahih al-bukhari:6324 Chapter: For every Prophet there is one invocation surely granted Book 80, Hadith 21

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). ”
