“One who memorized the first ten verses of Surah al Kahf will be secure against the Dajjal (Anti-Christ).” (Muslim)
Dajjal is one of the prominent figures of end of times and he will bring destruction to mankind. He will bring destruction and havoc to the world and because of his might people with low and weak faith will turn towards him and gather with him. At that time those who believe will ask help from ALLAH Almighty to protect them against his destruction. Therefore, if one wishes to be safe during the time of such grave adversity and annihilation, then one should try to memorize the first ten verses of Surah al Kahf and try reciting them whenever the chance becomes available.
Hazrat Ibn Mardwiyah Al Daiyaa (RA) said that Prophet Muhammad (Peace Be Upon Him) said in a hadith:
“Whoever reads Surah al Kahf on yaumul Jummah, he is immune for 8 days from all fitnah that will happen. When the Dajjal comes out, he will be immune to him.”
