The dua before sleeping is an excellent way to remember Allah when ending the day. It is a popular saying that sleep is a mini death; hence, it makes sense to remember Allah, thank Him for His blessings, and beseech Him to grant us life after the mini sleep. The dua is a way of ensuring that a believer has the blessings and protection of Allah (سُبْحَانَهُ وَتَعَالَى) with them while they're deep into slumber and unconscious of the happenings around them. It is mustahab to recite the dua before sleeping every night.
A person is unaware of their surroundings while sleeping. If a person reads the dua before falling asleep and then dies in their sleep, they will die in a state of fitrah (Sahih al-Bukhari 6313). The dua is also a great way of thanking Allah (سُبْحَانَهُ وَتَعَالَى) for His provisions and sustenance (Jami` at-Tirmidhi 3396). Another dua to be recited before falling asleep praises Allah (سُبْحَانَهُ وَتَعَالَى) and His attributes, and thus the reciter becomes the recipient of a great number of blessings and rewards ( Sahih Muslim 2713 a).

Allah! There is no God but He, the Ever Living, the One Who sustains and protects all that exists. Neither slumber nor sleep overtakes Him. To Him belongs whatever is in the heavens and whatever is on the earth. Who is he that can intercede with Him except with His Permission? He knows what happens to them in this world, and what will happen to them in the Hereafter. And they will never encompass anything of His Knowledge except that which He wills. His Throne extends over the heavens and the earth, and He feels no fatigue in guarding and preserving them. And He is the Most High, the Most Great.(Whoever reads this when he lies down to sleep will have a guardian from Allah remain with him and Satan will not be able to come near him until he rises in the morning.)

The Messenger has believed in what was revealed to him from his Lord, and [so have] the believers. All of them have believed in Allah and His angels and His books and His messengers, (saying), "We make no distinction between any of His messengers." And they say, "We hear and we obey. (We seek) Your forgiveness, our Lord, and to You is the (final) destination."(1)Allah does not charge a soul except (with that within) its capacity. It will have (the consequence of) what (good) it has gained, and it will bear (the consequence of) what (evil) it has earned. "Our Lord, do not impose blame upon us if we have forgotten or erred. Our Lord, and lay not upon us a burden like that which You laid upon those before us. Our Lord, and burden us not with that which we have no ability to bear. And pardon us; and forgive us; and have mercy upon us. You are our protector, so give us victory over the disbelieving people."(2)(These two Verses will be sufficient for anyone who recites them at night before sleeping.)Allah burdens not a person beyond what he can bear. He gets reward for that (good) which he has earned, and he is punished for that (evil) which he has earned. Our Lord! Punish us not if we forget or fall into error. Our Lord! Lay not on us a burden like that which You did lay on those before us. Our Lord! Put not on us a burden greater than we have strength to bear. Pardon us and grant us forgiveness. Have mercy on us. You are our Protector, and help us against the disbelieving people.
Bismika Rabbee wadha'tu janbee , wa bika 'arfa'uhu, fa'in 'amsakta nafsee farhamhaa, wa 'in 'arsaltahaa fahfadhhaa, bimaa tahfadhu bihi 'ibaadakas-saaliheen.
With Your Name my Lord, I lay myself down and with Your Name I rise. And if my soul You take, have mercy on it, and if You send it back then protect it as You protect Your righteous slaves.(If any of you rises from his bed and later returns to it, let him dust off his bed with his waist garment three times and mention the Name of Allah, for he does not know what may have entered the bed after him, and when he lies down he should say: بِسْمِ اللَّهِ
Allaahwmma 'innaka khalaqta nafsee wa 'Anta tawaffaahaa, laka mamaatuhaa wa mahyaahaa, 'in 'ahyaytahaa fahfadhhaa, wa 'in 'amattahaa faghfir lahaa . Allaahumma 'innee 'as'alukal-'aafiyata.
O Allah, You have created my soul and You take it back. Unto You is its death and its life. If You give it life then protect it, and if You cause it to die then forgive it. O Allah, I ask You for strength.
Allaahumma qinee 'athaabaka yawma tab'athu 'ibaadaka.
O Allah, save me from Your punishment on the Day that You resurrect Your slaves. (Three times)(When the Prophet saw wanted to lie down to sleep, he used to place his right hand under his cheek and says this dua'.)
Bismika Allaahumma 'amootu wa 'ahyaa.
In Your Name, O Allah, I die and I live.

O Allah! Lord of the Seven heavens and Lord of the Magnificent Throne. Our Lord and the Lord of everything. Splitter of the grain and the date-stone, Revealer of the Torah and the Injeel and the Furqan (the Qur'an), I seek refuge in You from the evil of everything that You shall seize by the forelock. O Allah You are the First and nothing has come before you, and You are the Last, and nothing may come after You. You are the Most High, nothing is above You and You are the Most Near and nothing is nearer than You. Remove our debts from us and enrich us against poverty.
Alhamdu lillaahil-lathee 'at'amanaa wa saqaanaa, wa kafaanaa, wa 'aawaanaa, fakam mimman laa kaafiya lahu wa laa mu'wiya.
Praise is to Allah Who has provided us with food and with drink, sufficed us and gave us an abode for how many are there with no provision and no home.
Allaahumma 'Aalimal-ghaybi wash-shahaadati faatiras-samaawaati wal'ardhi, Rabba kulli shay 'in wa maleekahu, 'ash-hadu 'an laa 'ilaaha 'illaa 'Anta, 'a'oothu bika min sharri nafsee, wa min sharrish-shaytaani wa shirkihi, wa 'an 'aqtarifa 'alaa nafsee soo 'an, 'aw 'ajurrahu 'ilaa Muslimin.
O Allah, Knower of the unseen and the evident, Maker of the heavens and the earth, Lord of everything and its Master, I bear witness that there is none worthy of worship but You. I seek refuge in You from the evil of my soul and from the evil of Satan and his helpers. (I seek refuge in You) from bringing evil upon my soul and from harming any Muslim.
Recite Surah 32 (As-Sajdah) and Surah 67 (Al-Mulk).
Allaahumma 'aslamtu nafsee 'ilayka, wa fawwadhtu 'amree 'ilayka, wa wajjahtu wajhee 'ilayka, wa 'alja'tu dhahree 'ilayka, raghbatan wa rahbatan 'ilayka, laa maalja' wa laa manja minka 'illaa 'ilayka, 'aamantu bikitaabikal-lathee 'anzalta wa bi-nabiyyikal-lathee 'arsalta.
O Allah, I submit myself to You, entrust my affairs to You, turn my face to You, and lay myself down depending upon You, hoping in You and fearing You. There is no refuge, and no escape, except to You. I believe in Your Book (the Qur'an) that You revealed, and the Prophet whom You sent.(Before you go to bed perform ablutions as you would for prayer, then lie down on your right side and says this dua'. Whoever says this and dies in his sleep, has died in a state of the natural monotheism (Fitrah).)
As per the Sunnah and the relevant Hadith, the Prophet Muhammad (ﷺ) would lay on his right side before sleeping, put his right hand under his face, and then recite the dua before sleeping. The dua should be recited keeping in mind the uncertainty that life holds and that there remains no guarantee of waking up after.
There are numerous benefits and advantages associated with the dua before sleeping. It is an excellent way of thanking Allah (سُبْحَانَهُ وَتَعَالَى) at the end of the day. The dua calls for protection from Allah (سُبْحَانَهُ وَتَعَالَى), Who appoints angels as guardians over the reciter and at his bedside for the entire duration of the night. Satan cannot harm the person in any way who recites the dua before sleeping. It is an outstanding method of asking for the blessings and bounties of Allah (سُبْحَانَهُ وَتَعَالَى), and the person is rewarded in the best way possible for these acts of his.
