باب مَا يَقُولُ إِذَا أَصْبَحَ
Sahih al-Bukhari 6324

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). "

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، عَنْ رِبْعِيِّ بْنِ حِرَاشٍ، عَنْ حُذَيْفَةَ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا أَرَادَ أَنْ يَنَامَ قَالَ ‏"‏ بِاسْمِكَ اللَّهُمَّ أَمُوتُ وَأَحْيَا ‏"‏‏.‏ وَإِذَا اسْتَيْقَظَ مِنْ مَنَامِهِ قَالَ ‏"‏ الْحَمْدُ لِلَّهِ الَّذِي أَحْيَانَا بَعْدَ مَا أَمَاتَنَا، وَإِلَيْهِ النُّشُورُ ‏"‏‏.‏
