Abu Hurairah (RA) reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as say ing: When any one of you goes to bed, he should take hold of the hem of his lower garment and then should clean (his bed) with the help of that and then should recite the name of Allah for he himself does not know what he left behind him on his bed, and when he intends to lie on bed, he should lie on his right side and utter these words: "Hallowed be Allah, my Lord. It is with Thine (grace) that I place my side (upon the bed) and it is with Thee that I take it up (after sleep), and in case Thou withholdst my being (if thou causest me to die), then grant pardon to my being, and if Thou keepst (this process of breathing on), then protect it with that with which Thou protected Thine pious servants."

This hadith has been narrated on the authority of Ubaidullah bin 'Umar with the same chain of transmitters and he said: Then utter: "My Lord. With Thine name I place my side and if Thou keepest me alive have mercy upon myself"

Anas reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: When you go to bed, say: "Praise is due to Allah Who fed us, provided us drink, sufficed us and provided us with shelter, for many a people there is none to suffice and none to provide shelter."
