Al-Bara' reported that whenever Allah's Messenger (ﷺ) went to bed, he said:" O Allah, it is with Thine Name that I live and it is with Thine Name that I die." And when he got up he used to say:" Praise is due to Allah, Who gave us life after our death (sleep) and unto Thee is resurrection."
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي السَّفَرِ، عَنْ أَبِي بَكْرِ بْنِ أَبِي مُوسَى، عَنِ الْبَرَاءِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ إِذَا أَخَذَ مَضْجَعَهُ قَالَ " اللَّهُمَّ بِاسْمِكَ أَحْيَا وَبِاسْمِكَ أَمُوتُ " . وَإِذَا اسْتَيْقَظَ قَالَ " الْحَمْدُ لِلَّهِ الَّذِي أَحْيَانَا بَعْدَ مَا أَمَاتَنَا وَإِلَيْهِ النُّشُورُ " .
Muslim
