The Prophet (ﷺ) commanded us to recite the opening verses of Soorat al-Kahf against the Dajjaal. According to some reports, the final verses of this surah were mentioned. This means reciting the first ten verses or the last ten. Among the ahaadeeth narrated concerning this was the lengthy hadeeth narrated by Muslim from al-Nawwaas ibn Sam’aan (رضي الله عنه), in which it says:
“Whoever among you sees him (the Dajjaal), let him recite against him the opening verses of Soorat al-Kahf.”
Narrated from Abu’l-Dardaa’ (رضي الله عنه) that the Prophet (ﷺ) said:
“Whoever memorizes ten aayaat from the beginning of Soorat al-Kahf will be protected from the Dajjaal” – i.e., from his fitnah. Muslim said: “Shu’bah said, ‘from the end of al-Kahf.’ Hammaam said, ‘from the beginning of al-Kahf.’
Al-Nawawi (رَحِمَهُ ٱللَّٰهُ) said: “The reason for this is because at the beginning of (this soorah), mention is made of wonders and signs, and whoever ponders them will not be deceived by the fitnah of the Dajjaal. And at the end of this soorah, Allaah says: ‘Do then those who disbelieve think that they can take My slaves as awliyaa’ (lords etc.) besides Me?’ [al-Kahf 18:102].”
(Sharh Sahih Muslim, 6/93).
This is one of the special features of Soorat Al-Kahf. There are ahaadeeth which encourage reading it, especially on Fridays. Al-Haakim (رَحِمَهُ ٱللَّٰهُ) narrated from Abu Sa’eed al-Khudri (رضي الله عنه) that the Prophet (ﷺ) said:
“Whoever recites Soorat al-Kahf on Friday, it will be a light for him from one Friday to the next.”
(Al-Mustadrak, 2/368. ClassSaheehSaheeh by al-Albaani, Saheeh al-Jaami’ al-Sagheer, hadeeth 6346)
Undoubtedly Soorat Al-Kahf is of great significance, containing great aayaat, such as the story of the People of the Cave, the story of Moosa and al-Khidr, the story of Dhu’l-Qarnayn and his built ding of the dam to hold back Ya’jooj and Ma’jooj, proof of the resurrection and the blowing of the Trumpet, and explanation of those whose deeds are most lost, who are those who think that they are guided when in fact they are misguided and blind.
Every Muslim should strive to read this soorah memorize it and read it repeatedly, especially on the best day on which the sun rises, namely Friday.
Fleeing from the Dajjaal and keeping far away from him.
The best way is to live in Makkah or Madeenah, places which the Dajjaal will not enter. When the Dajjaal emerges, Muslims should keep far away from him, because of the confusion he will cause and the mighty wonders that he will have with him, which Allaah (ﷻ) will cause to happen at his hands in otot mankind. A man will come to him, thinking that he is a strong believer, and then he will follow the Dajjaal. We ask Allaah (ﷻ) to grant us and all the Muslims refuge from his fitnah.
Narrated from ‘Imraan ibn Husayn (رضي الله عنه) that the Prophet (ﷺ) said:
“Whoever hears of the Dajjaal, let him keep far away from him, for a man will come to him and think that he is telling the truth because of the wonders that are sent with him.”
