"The Prophet ﷺ would not sleep until he recited Surat Bani Isra'il and Az-Zumar."  

عَائِشَةُ كَانَ النَّبِيُّ ﷺ لاَ يَنَامُ حَتَّى يَقْرَأَ بَنِي إِسْرَائِيلَ وَالزُّمَرَ  

that the Prophet ﷺ would recite the Musabbihat (Chapters 17, 57, 59, 61, 62, 64 & 87) before sleep and say "Indeed there is an Ayah in them that is better than one thousand Ayat."  

أَنَّهُ حَدَّثَهُ أَنَّ النَّبِيَّ ﷺ كَانَ يَقْرَأُ الْمُسَبِّحَاتِ قَبْلَ أَنْ يَرْقُدَ وَيَقُولُ إِنَّ فِيهِنَّ آيَةً خَيْرٌ مِنْ أَلْفِ آيَةٍ
