It is narrated from Sayyiduna Hudhayfah (may Allah be pleased with him) that when the Prophet (peace and blessings of Allah be upon him) intended to sleep, he would say: "With Your name, O Allah, I die and I live." And when he would wake up from sleep, he would say: "All praise is for Allah who gave us life after causing us to die, and to Him is the resurrection."

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) would come to his bed, he would recite this supplication: «الْحَمْدُ لِلَّهِ الَّذِي ......» ‏‏‏‏“All praise is for Allah who has fed us, given us drink, sufficed us, and provided us with shelter, and how many are there who have no one to suffice them or provide them with shelter.”

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) would certainly recite Surah Sajdah and Surah Mulk before sleeping. Abu Zubair says that these two surahs have seventy more virtues than every other surah of the Noble Qur'an; whoever recites both of them will have the reward of seventy good deeds written for him, his seventy ranks will be elevated, and seventy of his sins will be erased through them.

It is narrated from Sayyiduna Abdullah (may Allah be pleased with him), he says that sleep during the time of remembrance is from Satan. If you wish, you may try it. When any of you goes to bed and intends to sleep, he should remember Allah, the Mighty and Majestic.

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) would not go to sleep until he had recited Surah Al-Mulk and Alif Lam Meem As-Sajdah.

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When one of you goes to lie down on his bed, he should take the edge of his waist-wrapper and dust off his bed with it, for he does not know what may have come onto it after him. Then he should lie down on his right side and recite this supplication: 'In Your name, O Allah, I lay down my side. So if You take my soul, have mercy on it, and if You let it go, protect it as You protect Your righteous servants.' Or he said: 'As You protect Your righteous slaves.'"

It is narrated from Sayyiduna Bara’ bin Azib (may Allah be pleased with both of them) that when the Prophet (peace and blessings of Allah be upon him) would go to his bed, he would lie down on his right side, then recite this supplication:“O Allah! I have turned my face towards You, and I have entrusted my soul to You, and I have relied upon You, fearing You and desiring Your blessings. There is no refuge and no place of safety except with You. I believe in Your Book which You have revealed, and in Your Prophet whom You have sent.”Then he said:“Whoever recites these words (with faith and certainty) at night and then dies that night, his death will be upon the natural disposition (fitrah).”

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) lay down on his bed, he would recite: "O Allah! Lord of the heavens and the earth, Owner of all things, Splitter of the grain and the date-stone, Revealer of the Torah, the Gospel, and the Qur'an. I seek refuge in You from the evil of every creature whose forelock is in Your hand. You are the First, there is nothing before You, and You are the Last, there is nothing after You. You are the Most High, there is nothing above You. You are the Most Near, there is nothing beyond You. Settle my debt for me and enrich me, relieving me from poverty."

It is narrated from Sayyiduna Bara’ bin ‘Azib (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings of Allah be upon him) would come to his bed, he would lie down on his right side, then recite: «اللَّهُمَّ أَسْلَمْتُ ......» ‏‏‏‏“O Allah! I have submitted my soul to You, I have turned my face towards You, I have entrusted my affairs to You, and I have relied upon You in all my matters, hoping in You and fearing You. There is no refuge and no escape from You except with You. I believe in Your Book which You have revealed and in Your Prophet whom You have sent.”The Messenger of Allah (peace and blessings of Allah be upon him) said:“Whoever recites these words and then dies that night, dies upon the natural disposition (fitrah).”

It is narrated from Sayyiduna Jabir (may Allah be pleased with him), he said: When a man enters his house or goes to his bed, an angel and a devil hasten towards him. The angel says: End your work with goodness. The devil says: End your work with evil. So if he praises and remembers Allah, the angel drives the devil away and protects him throughout the night. Then when he wakes up, again the angel and the devil hasten towards him, and both repeat the previous conversation. So if he remembers Allah and says: All praise is due to the One who returned my soul to me after death and did not cause me to die in my sleep. All praise is due to the One "who holds the heavens and the earth lest they move from their places. If they were to move, who could hold them after Him? Surely, He is Most Forbearing, Most Forgiving." [سورہ فاطر: 41] All praise is due to Allah "who holds the heavens from falling upon the earth except by His permission... Surely, He is Most Kind, Most Merciful." [سورہ الحج: 65] If he dies, he dies the death of a martyr, and if he gets up and prays, it will be a prayer of great virtue.
