Abu Huraira reported God’s messenger as saying that when any of them went to bed he should dust his bedding with the inner extremity of his lower garment, for he does not know what has come on to it since he left it. He should then say, “In Thy name, my Lord, I lay down my side and in Thee I raise it up. If Thou keepest my soul have mercy on it, but if Thou lettest it go guard it with that with which Thou guardest Thy upright servants.” A version says that he should then lie down on his right side and say, “In Thy name...” (Bukhari and Muslim). A version says he should dust it three times with the border of his garment, and has “If Thou keepest my soul grant it pardon.”
