Duas for sleep & night. Before bed, through the night

Allahu la ilaha illa Huwa, al-Hayyu-l-Qayyum. La ta'khudhuhu sinatun wa la nawm. Lahu ma fi-s-samawati wa ma fi-l-ard. Man dha-lladhi yashfa'u 'indahu illa bi-idhnih. Ya'lamu ma bayna aydihim wa ma khalfahum, wa la yuhituna bi-shay'in min 'ilmihi illa bi-ma sha'. Wasi'a kursiyyuhu-s-samawati wa-l-ard, wa la ya'uduhu hifdhuhuma, wa Huwa-l-'Aliyyu-l-'Adheem.
“Allah, there is no god but He, the Living, the Self-Subsisting. Neither slumber nor sleep overtakes Him. To Him belongs what is in the heavens and what is on the earth. Who can intercede with Him except by His permission? He knows what lies before them and what is behind them, and they grasp nothing of His knowledge except what He wills. His Throne extends over the heavens and the earth, and their preservation does not tire Him. He is the Most High, the Most Great.”
Quran 2:255
Reciting this at evening protects from jinn until morning.
Qul a'udhu bi Rabbi-l-falaq. Min sharri ma khalaq. Wa min sharri ghasiqin idha waqab. Wa min sharri-n-naffathati fi-l-'uqad. Wa min sharri hasidin idha hasad.
“Say: I seek refuge with the Lord of the daybreak. From the evil of what He has created. From the evil of the darkening night as it descends. From the evil of those who blow into knots. And from the evil of the envier when he envies.”
Qul a'udhu bi Rabbi-n-nas. Maliki-n-nas. Ilahi-n-nas. Min sharri-l-waswasi-l-khannas. Alladhi yuwaswisu fi suduri-n-nas. Mina-l-jinnati wa-n-nas.
“Say: I seek refuge with the Lord of mankind. The King of mankind. The God of mankind. From the evil of the whispering one who withdraws. Who whispers in the breasts of mankind. From among the jinn and mankind.”
A'udhu bi kalimati-llahi-t-tammati min ghadabihi wa 'iqabih, wa sharri 'ibadih, wa min hamazati-sh-shayatini wa an yahdurun.
“I seek refuge in Allah's perfect words from His anger and punishment, from the evil of His servants, and from the whispers of the devils and from their presence.”

The Prophet ﷺ said that when one of you is frightened in his sleep, let him say this, and it will not harm him. Al-Albani graded it hasan; Zubair Ali Za'i graded it weak (da'if).
