Adabul Mufrad — Hadith #36463

The Prophet (PBUH) said: When one of you comes to sleep in his bed, he should shake his bed with the lower part of his garment and remember the name of Allah. Because he does not know what has fallen into his bed in his absence. When he sleeps in bed Then let him lie on his right ear and say, "Holy is my Lord. In Your name I put my side to bed and in Your name I will raise it. If You spare my life, forgive him. And if You let him go, protect him as You are yours." Protect the righteous servants.” (Bukhari, Muslim, Darimi, Ibn Hibban)
