Dua Before Sleeping
Seeking Allah's protection before sleep
بِاسْمِكَ رَبِّي وَضَعْتُ جَنْبِي وَبِكَ أَرْفَعُهُ فَإِن أَمْسَكْتَ نَفْسِي فَارْحَمْهَا وَإِنْ أَرْسَلْتَهَا فَاحْفَظْهَا بِمَا تَحْفَظُ بِهِ عِبَادَكَ الصَّالِحِين
Bismika Rabbi wada'tu janbi wa bika arfa'uh, fa in amsakta nafsi farhamha, wa in arsaltaha fahfazha bima tahfazu bihi 'ibadakas-saliheen.
In Your name, my Lord, I lie down and in Your name I rise, so if You should take my soul then have mercy upon it, and if You should return my soul then protect it in the manner You do so with Your righteous servants.
