The Messenger of Allah ﷺ used to recite al-Musabbihat before going to sleep, and say: They contain a verse which is better than a thousand verses. (Using translation from Abū Dāʾūd 5057)
أَنَّ النَّبِيَّ ﷺ كَانَ يَقْرَأُ الْمُسَبِّحَاتِ قَبْلَ أَنْ يَرْقُدَ وَيَقُولُ «إِنَّ فِيهَا أَيَّةً أَفْضَلَ مِنْ أَلْفِ آيَةٍ»
