رِيَاضُ الصَّالِحِينَ
Riyad as-Salihin 1458
The Book of the Remembrance of Allah
Supplication before going to Bed
وَعَنْ حذيفة وَأَبِي ذَرٍّ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ كَانَ إِذَا أَوَى إِلَى فِرَاشِهِ قَالَ: بِاسْمِكَ اللهم أحيا وأموت ((رَوَاهُ الْبُخَارِيّ)).
Hudhaifah and Abu Dharr (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) used to supplicate when he went to bed at night: "Bismik-Allahumma ahya wa amut (With Your Name, O Allah, I expire and return to life)." [Al- Bukhari].
