Mishkatul Masabih — Hadith #39938

He said, Rasoolullah Sallallahu Alaihi Wasallam said: When one of you sleeps in bed, let him shake the bed with the inside of his clothes. Because he does not know what has come to bed. Then let him recite this dua,\n\n''Wonder Rabbi wa ya'tu jambi wabika arfa'uh in amsakta nafsi farhamha- wa in arsaltaha- fahfazaha- bima- tahfazu bihi 'iba-dakas sa-lihin''\n\n(meaning- O Lord! In Your name I lay down my body and in Your name I will raise it again. If You raise my soul Hold back (from death), but have mercy on my soul. And if you leave it, then protect it, with which You protect Your righteous servants.). In another narration, then let him sleep on his right side, then say, "Bishmika" (meaning- In your name). (Bukhari, Muslim) [1]
