Mufti Sahib,I want to know about Dajjaal;who is he? and how we can save ourselves from his fitnah?

Answered according to Hanafi Fiqh by

Dajjaal will be a Jew and he will have the same ideology as the Jews and
other Kuffaars. They will use one another and be common enemies of Muslims
and Islam.

Hadhrat Ali (Radhiallaahu Anhu) narrates that Rasulullah (Sallallaahu Alayhi
Wasallam) said, ‘Whosoever recites Surah Kahf on Friday, he will be saved
from evil for eight days and if Dajjaal emerges, he will be saved from the
evils of Dajjaal.’ (Ma’riful Qur’aan vol.4 pg.546; Rabbaani Bookdepot)

and Allah Ta’ala Knows Best
