Surah al-Kahf

The Prophet (salAllahu alayhi wasalam) said,‘Whoever recited Surah al Kahf on a Friday, Allah will kindle for him abundant light to brightly illuminate the period between the two Fridays (the Friday on which the recitation was made and the next Friday)’[Hakim 2/367, Mishkat al-Masabih #2175, however Baihaqi disagreed with it’s authenticity in Sahih Al Jami 2/1104]Source: Iqra
