Ash-Shama'il Al-Muhammadiyah: The Sleeping Of Rasoolullah

“When the Prophet (Allah bless him and give him peace) lay down to sleep, he placed the palm of his right hand under his right cheek and said: ‘O my Lord, preserve me from Your torment on the day when You resurrect Your servants!'”

“When the Prophet (Allah bless him and give him peace) went to his mattress, he would say: ‘O Allah, in Your Name I shall die and live,’ and when he woke up, he would say: ‘Praise be to Allah, who has revived us after He caused us to die, and to Him is the resurrection!'”

"When Allah’s Messenger (Allah bless him and give him peace) went to his mattress each night, he joined the palms of his hands, then breathed into them and recited into them: “Say: ‘He is Allah, One [qul Huwa'llahu Ahad]!' (Al-Qur'an;112:1), and: “Say: ‘I take refuge with the Lord of the Daybreak [qul a'udhu bi-Rabbil-falaq]!' (Al-Qur'an;113:1), and: “Say: ‘I take refuge with the Lord of humankind [qul a'udhu bi-Rabbi’n-nas]!' (Al-Qur'an;114:1), Then he passed them over as much of his body as he could, beginning with his head and his face and the front of his body, doing that three times.”

“Allah’s Messenger (Allah bless him and give him peace) slept until he gasped for breath, and he had gasped for breath while he was sleeping, so Bilal came to him and called him to the ritual prayer, whereupon he got up and performed the ritual prayer, and he did not perform the minor ritual ablution. And there is a story behind this tradition."

“When Allah’s Messenger (Allah bless him and give him peace) went to his mattress, he would say: ‘Praise be to Allah, who has fed us and quenched our thirst, and has sufficed us and sheltered us, for how many there are without a provider of sufficiency and without a provider of shelter!'”

“When the Prophet (Allah bless him and give him peace) alighted for rest at night, he would recline on his right side, and when he alighted for rest shortly before the morning, he would raise his forearm and place his head on the palm of his hand.”
