Baraa Radiyallahu 'Anhu reports:
"When Rasulullah Sallallahu 'Alayhi Wasallam retired, he put his right hand under his right cheek, and recited this du'aa: Rabbi qini adhaa-baka yauma tub-a-thu 'ibaadaka.Translation... O Allah, save me from Your punishment on the day of qiyaamah".
Hudhayfah Radiyallahu 'Anhu says:
"When Rasulullah Sallallahu 'Alayhi Wasallam lay down on a bed, he recited: Allahurmma bi-ith-mika a-mutu wa ahyaa.Translation... O Allah! In Thy name do I live and die".When he awakened he recited this du'aa: Alhamdulillaahil ladhi ahyaanaa ba'da rnaa amaatana wa-ilayhin nushur.Translation...'Praise be to Allah Who restored unto us life, having caused us to die and unto Him shall be the Resurrection"'.
'Aayeshah Radiyallahu 'Anha narrates:
"Every night before Rasulullah Sallallahu 'Alayhi Wasallam slept on his bed, he put together his hands (as in the du'aa) and blew on it and recited (the surahs of) AI-Ikhlaas (Qul huwauahu ahad), AI-Falaq (Qul a'udhu birabbil falaq), and An-Naas (Qui a'udhu birabbin naas) and wiped those parts of the body that he could (wherever the hand could reach). He began with the head, then the face and then the front part of his body. This was done thrice".
Ibn 'Abbaas Radiyallahu 'Anhu reports:
"Once Rasulullah Sallallahu 'Alayhi Wasallam slept and began snoring. It was, the nature of Rasulullah Sallallahu 'Alayhi Wasallam that he snored, when he slept. Bilaal Radiyallahu 'Anhu gave the call to prepare for salaah. Rasulullah Sallallahu 'Alayhi Wasallam awakened and performed the salaah. He did not perform the wudu". This hadith has a detailed incident
Anas bin Maalik Radiyallahu'Anhu says:
"When Rasulullah Sallallahu 'Alayhi Wasallam went to bed, he recited this du'aa:Alhamdulillaahil ladhi at'a-manaa wa-saqaanaa wa-kafaanaa wa-aa-waa-naa-fa-kam mim-mal laa kaafiya lahu wa-laa mu-wiya.Translation...'Praise be to Allah Who gave us food and drink, provided us sufficiently, and gave us (a place for) shelter! How many there are who have neither a provider nor a shelterer!'
Abu Qataadah Radiyallahu 'Anhu relates:
"If Rasulullah Sallallahu 'Alayhi Wasallam made an early journey-break in the last portion of the night on his travels, he slept on his right side. If he was staying there till before the morning, he lifted his right arm, put his head on it and slept".
