Which Qur’anic Surahs are preferred for daily recitation as regular devotions, and what is their merit for the Muslim, like Surat Al-Kahf which is recited on the eve of Friday?

The باب of dhikr (remembrance of Allah) is vast, and a Muslim should maintain the adhkar (forms of remembrance) mentioned in the Sunnah (definition) or the Qur’an. There are books that compile adhkar, such as "Al-Wabil Al-Sayyib," "Al-Kalim Al-Tayyib (definition)," and "Al-Adhkar" by Al-Nawawi. Among the recited verses and surahs are: Al-Ikhlas (definition), Al-Mu'awwidhatayn, the last two verses of Al-Baqarah, and Ayah Al-Kursiyy. And the verse from Surah (definition) At-Tawbah (definition): "Sufficient for me is Allah; there is no deity except Him. On Him I have relied, and He is the Lord of the Great Throne," is to be recited seven times in the morning and in the evening. And Surah Al-Mulk and Surah As-Sajdah are recited before sleeping.
