Which surahs or verses is it recommended to recite daily or at specific times, and is it permissible to recite them during the Qiyam al-Layl prayer every night?

It is recommended to recite Ayatul Kursi, the last verses of Surat Al-Baqarah, Surat Al-Ikhlas, Surat Al-Falaq, and Surat An-Nas every night before sleeping. There is no authentic hadith that proves the virtue of reciting Surat Al-Waqi'ah every night. The virtue of reciting Surat As-Sajdah and Surat Al-Mulk has been established. There is no specific surah recommended to be recited every night during Qiyam Al-Layl (night prayer), but there is no harm in reciting a specific surah without believing it to be a Sunnah practice.
