Hazrat Abu Huraira narrates that the Messenger of Allah, peace and blessings be upon him, said: When any of you intends to lie down on his bed, he should remove the extra clothes from underneath him, then he should dust off his bed, because he does not know what might have come onto his bed after him. Then he should lie down on his right side, then recite this supplication: My Lord, in Your name I have placed my side, and in Your name I will raise it. So if You take my soul, have mercy on it. And if You leave it alive, protect it with the protection with which You protect Your righteous servants.
