BUKHARI 6325: from Abū Dhar —
Whenever the Prophet ﷺ lay on his bed, he used to say: "Allahumma bismika amutu wa ahya," and when he woke up he would say: "Al-hamdu lil-lahilladhi ahyana ba'da ma an atana, wa ilaihi an-nushur."

البخاري ٦٣٢٥: عن ابو ذر —
كَانَ النَّبِيُّ ﷺ إِذَا أَخَذَ مَضْجَعَهُ مِنَ اللَّيْلِ قَالَ اللَّهُمَّ بِاسْمِكَ أَمُوتُ وَأَحْيَا فَإِذَا اسْتَيْقَظَ قَالَ الْحَمْدُ لِلَّهِ الَّذِي أَحْيَانَا بَعْدَ مَا أَمَاتَنَا وَإِلَيْهِ النُّشُورُ
