Reciting Ayatul Kursi at Night

It is considered a sunnah to recite Āyat al-Kursī daily, especially before you go to sleep. According to a narration in Bukhārī, if you recite Āyat al-Kursī from start to finish as you settle into your bed, Allah will assign a guardian angel to watch over you throughout the night until morning.
