hm...well then for this i have to check Surah Qaf, cuz all i know that only Hadith-e-Mubarik talks about Zahoor-e-Dajjal.
cuz if Quran talks about him then there wont any discrepancies of him coming and spreading his fitna.
my bad, I doubled checked and my mistake for saying that there is a mention about dajjal in Surah Kahf - infact it says by reading first 10 ayats n last 10 ayats of this particular surah will help you avoid Dajjal when he/i arrives.
