Dua before sleeping — in Your name I lie down and rise
If one of you rises from his bed and then returns to it, he should dust it with the edge of his garment three times, for he does not know what has occurred in his absence, and when he lies down, he should supplicate:
بِاسْمِـكَ رَبِّـي وَضَعْـتُ جَنْبِـي، وَبِكَ أَرْفَعُـهُ، فَإِنْ أَمْسَـكْتَ نَفْسِـي فَارْحَـمْهَا، وَإِنْ أَرْسَلْتَـهَا فَاحْفَظْـهَا بِمَـا تَحْفَـظُ بِـهِ عِبَـادَكَ الصَّـالِحِـينَ
Bismika rabbī waḍa‘tu janbī, wa bika arfa‘uh, fa’in amsakta nafsī fa-rḥamhā, wa in arsaltahā fa-ḥfaẓhā bimā taḥfaẓu bihi ‘ibādaka ṣ-ṣāliḥīn.
Translation
In Your name, my Lord, I lay 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.
When to recite
Before going to sleep.
