It was narrated from Abu Hurairah that: when going to bed, the Prophet (saas) used to say: "Allahumma Rabbas-samawati wa Rabbal-ardi, wa Rabba kulli shay'in, faliqal-habbi wan-nawa, munzilat-Tawrati wal-Injili wal-Qur'anil-'Azim. A'udhu bika min sharri kulli dabbatin Anta akhidhun binasiyatiha, Antal-Awwalu fa laysa qablaka shayun, wa Antal-Akhiru, fa laysa ba'daka shayun', Antaz-zahiru, fa laysa fawqaka shayun', wa antal-batinu fa laysa dunaka shay', aqdi 'annid-dayna waghnini minal-faqr (O Allah, Lord of the heavens and Lord of the earth and Lord of all things, Cleaver of the seed and the kernel, Revealer of the Tawrah, the Injil and the Magnificent Qur'an, I seek refuge with You from the evil of every creature You seize by the forelock. You are the First and there is nothing before You; You are the Last and there is nothing after You; You are the Most High (Az-Zahir) and there is nothing above You, and You are the Most Near (Al-Batin) and there is nothing nearer than You. Settle my debt for me and spare me from poverty)."

It was narrated from Abu Hurairah that: the Messenger of Allah (saas) said: "When anyone of you wants to go to bed, let him undo the edge of his Izar (waist wrap) and dust of his bed with it, for he does not know what came to it after him. Then let him lie down on his right side and say: 'Rabbi bika wada'tu janbi wa bika arfa'uhu, fa in amsakta nafsi farhamha, wa in arsaltaha fahfazha bima hafizta bihi 'ibadikaas-salihin (O Lord, by Your leave I lie down and by Your leave I rise, so if You should take my soul then have mercy on it, and if You should return my soul then protect it as You protect Your righteous slaves)."

It was narrated from 'Aishah that: whenever the Prophet (saas) went to bed, he would blow into his hands, recite Al-Mu'awwidhatain, then wipe his hands over his body.

It was narrated from Bara' bin 'Azib that: the Prophet (saas) said to a man: "When you go to lay down, or go to your bed, say: Allahumma aslamtu wajhi ilayka, wa al-ja'tu zahri ilayka, wa fawwadtu amri ilayka, raghbatan wa rahbatan ilayka, la malja'a wa la manja'a minka illa ilayka, amantu bi kitabikal-ladhi anzalta, wa nabiyyikal arsalta [O Allah, I have submitted my face (i.e., myself) to You, and I am under Your command (i.e., I depend upon You in all my affairs), and I put my trust in You, hoping for Your reward and fearing Your punishment. There is no fleeing from You and no refuge from You except with You. I believe in Your Book that You have revealed and in Your Prophet whom You have sent).' Then if you die that night, you will die in a state of the Fitrah (nature), and if you wake in the morning you will wake with a great deal of good."

It was narrated from 'Abdullah that: whenever the Prophet (saas) went to his bed, he would put his hand - meaning his right hand - beneath his cheek then say: "Allahumma qini 'adhabaka yawm tab'athu - [or: tajma'u] - 'ibadaka (O Allah, save me from Your punishment on the Day when You resurrect - or gather - Your slaves)."
