When the Prophet (ﷺ) went to bed he said: “Allahumma bismika amutu wa ahya.” When he woke he said: “Al-hamdu lillahi alladhi ahyana ba‘da ma amatana wa ilayhi-n-nushur.” Hudhayfah also reported this wording (Bukhari 6312 / 6324). Night remembrance (اذكار النوم) also includes Ayat al-Kursi: whoever recites it when lying down has a protector from Allah and Shaytan does not approach until morning (Bukhari 2311).

Yes. Hisnul Muslim gathers the authentic night remembrances: this dua, Ayat al-Kursi, the last two verses of Al-Baqarah, and the mu‘awwidhat. Noor al-Dua teaches them word by word so they stay on the tongue at bedtime.
