بِاسْمِكَ رَبِّي وَضَعْتُ جَنْبِي وَبِكَ أَرْفَعُهُ إِنْ أَمْسَكْتَ نَفْسِي فَارْحَمْهَا وَإِنْ أَرْسَلْتَهَا فَاحْفَظْهَا بِمَا تَحْفَظُ بِهِ عِبَادَكَ الصَّالِحِينَ
Bismika Rabbi wada'tu janbi wa bika arfa'uh, in amsakta nafsi farhamha wa in arsaltaha fahfadhha bima tahfadhu bihi 'ibadakas-salihin
In Your Name, my Lord, I lay down my side, and by You I will rise. If You take my soul, have mercy on it, and if You release it, protect it as You protect Your righteous servants.
Two possible outcomes of sleep: Allah takes your soul permanently (death) or releases it back to you (waking up). This du'a covers both with elegant trust: if You keep it, show mercy; if You return it, give it the protection You give the righteous. You go to sleep not knowing which outcome awaits — and this du'a makes peace with either one.
