Many of us recite the glorious verses each and every Friday of Surah al- Kahf. Below are some of the merits of this Surah taken from Ma’ariful Qur’an By Mufti Muhammad Shafi
The properties and merits of Surah al-Kahf
According to a narration of Sayyidina Abu al-Darda (radi Allahu anhu) appearing in Muslim, Abu Dawud, Tirmdhi, al- Nasa’I, and the Musnad of Ahmad, one who memorized the first ten verses of Surah al-Kahf will remain protected from the ill effects of Dajjal (imposter). In another report in the same books and from the same authority, the same thing has been said about memorizing the last ten verses of Surah Kahf.
And it has been reported in the Musnad of Ahmad on the authority of Sayyidina Sahl ibn Mu’adh (radi Allahu anhu) that the Holy Prophet (sall Allahu alaihi wa sallam) said,” One who recites the first and last verses of Surah al- Kahf , for him there is light from his feet up to his head. And the one who were to recite the whole Surah, then, there is light from the earth up to the sky.”
And it appears in some narratives that a person who recites Surah al-Kahf on the day of Jumu’ah will have light from his feet up to the sky. This light will serve him well on the day of Qiyamah, and every sin committed by him between the past and present Jumu’ah will be forgiven.” (Imam ibn Kathir has declared this report to be mawquf (a Hadith the narration of which stops at a Sahabi and does not ascend to the Holy Prophet (sall Allahu alaihi wa sallam)
And Hafiz Zya’ Al-Maqdisi, in his book Al-Mukhtarah , has reported on the authority of Sayyidina Ali (radi Allahu anhu) that the Holy Prophet (sall Allahu alaihi wa sallam) said,” One who recites Surah al- Kahf on the day of Jumu’ah will remain protected from every fitnah. And if the Dajjal appears, he will stay safe against the trying challenges released by him as well.” (All these narrative reports have been taken from Tafsir ibn Kathir)
According to a report from Dailami on the authority of Sayyidina Anas (radi Allahu anhu) appearing in Ruh al-Ma’ani , the Holy Prophet (sall Allahu alaihi wa sallam) said, “ The entire Surah al-Kahf was revealed at one time seventy thousand angels came with it” –which shows its majesty”
