Surat Al Kahf has immense blessings.
Abu Darda’ reported Allah’s Apostle (may peace be upon him) as saying: If anyone learns by heart the first ten verses of the Surat Al-Kahf, he will be protected from the Dajjal. (Sahih muslim Book 004, Hadith 1766)
Abu Sa’id al-Khudri reports that the Prophet SAW said: “Whoever recites Surat Al-Kahf on Jumu’ah will have illumination from the light from one Jumu’ah to the next.” (an-Nasa’i, al-Baihaqi, and al-Hakim)
