عن حذيفة، وأبي ذر رضي الله عنهما
قالا: كان رسول الله صلى الله عليه وسلم: إذا أوى إلى فراشه قال: «باسمك اللهم أموت وأحيا«وإذا استيقظ قال: «الحمد لله الذي أحيانا بعد ما أماتنا وإليه النشور»
Whenever the Messenger of Allah (sallallahu alayhi wa sallam) went to bed, he would supplicate: “Bismika-Allahumma amut wa ahya (With Your Name, O Allah, I die and return to life)”; and when he woke up, he would supplicate thus: “Al-hamdu lillahilladhi ahyana bada ma amatana, wa ilaihin-nushur (All praise belongs to Allah Who has restored us back to life after causing us to die; and to Him shall we return).”
