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 يُقْرَأُ الْمُسَبِّحَاتِ قَبْلَ أَنْ يَرْقُدَ وَيَقُولُ «إِنَّ فِيهِنَّ آيَةً أَفْضَلُ مِنْ أَلْفِ آيَةٍ»
