Feeling refresh after reciting Surah A-Kahfi. :) It is sunnah to read this surah on the night before Friday or on Friday itself.
There is a hadith related to the recommendation to read this surah by Hakim Bayhaqi, from Abu Sa’id , “Whoever recites Surah Al-Kahfi on Friday, light shall shine forth for him between the two fridays.” (Ibnu Hajar, Talkhis al-Habir).

Happy Jumu’ah everyone.
