Regarding the recitation of Surah Kahf, both narrations of reciting it from
memory and also from the Quraan itself exist in the hadith.
a) ibn Mardawaih reports from ibn Umar marfooan: He who recites Surah Kahf
on the day of Jumuah, nur (light) will be spread out for him from below his
feet till the sky, it will shine for him till the Day of Judgement and hsi
sins between the two Jumuahs will be forgiven for him.
In Tafseere Roohul Ma’ani vol.8 pg. 288, under the tafseer of Surah Kahf,
there are three Ahaadith which support the recitation of Surh Kahf from the
Quraan and there also appear a few narrations on reciting from memory.
3) Surah Kahf can be recited on the night of Jumuah (Thursday night) or on
the Day of Jumuah. Narrations regarding its recitaiton at both times are
found in the treasure of Ahaadith.
a) ibn Mardawaih reports from Abdullah ibn Mughaffal marfooan: The home in
which Surah Kahf is recited, shaitaan does not enter that house on that
specific night. (Roohul Ma’ani, vol. 8, pg. 289).
Many Ulama are of the opinion that it is sunnat to recite Surah Kahf on the
Day of Jumuah and on the same token, many are of the view that is sunnat to
recite it on the Night of Jumuah and they also state that it will be
commendable to read it at both times. (Roohul Ma’ani, vol.8 pg. 289).
