First ten aayaat of Surah al-Kahf If anyone learns by heart the first ten verses of the Surah al-Kahf, he will be protected from the Dajjal. (Sahih Muslim: Book #004, Hadith #1766)But it should be noted that “learning by heart” also indicates implementing these aayat on ourselves. And the sufficient proof for this indication is the following hadith about the dream that Prophet Muhammed (pbuh) had:“He whose head was being crushed with a stone was one who learnt the Quran but never acted on it, and slept ignoring the compulsory prayers.” (Sahih Bukhari: Book #21, Hadith #244)Surah Kahf (The Cave) is the eighteenth (18th) Surah of the glorious Qur’an. Surah Kahf comes immediately after Surah Bani Israel (also known as Al-Isra). Because Dajjali fitnah is going to be the toughest test of the believers, therefore implementing these Aayaat is going to be toughest on the believers as well.Dajjal comes from the word Dajjl which means deceiver/ imposter. It is said in a hadith that there will arise 30 Dajjal before the real Dajjal appears (Sahih Bukhari: Book #88, Hadith #237). For example, Ghulam Ahmed Qadiyaani, who claimed to be a prophet was a Dajjal, an imposter, pretending to be a prophet.Now, let’s go through the aayat and try to understand how we can implement these aayat on ourselves and remain safe from the Dajjali fitnah.
