Sahih Muslim · Book 48: The Book Pertaining to the Remembrance of Allah, Supplication, Repentance and Seeking Forgiveness · Supplication When Going To Sleep
Al-Bara' reported that whenever Allah's Messenger (ﷺ) went to bed, he said:
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 " .
" 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."
