The moment you wake up
Sleep is a small death. These are the first words on returning from it.
الْحَمْدُ لِلَّهِ الَّذِي أَحْيَانَا بَعْدَ مَا أَمَاتَنَا وَإِلَيْهِ النُّشُورُ
Al-ḥamdu lillāhi-lladhī aḥyānā baʿda mā amātanā wa ilayhi-n-nushūr.
“All praise is for Allah, who gave us life after He caused us to die, and to Him is the return.”
