Who are the followers of the Dajjal, and who are the harshest on him?

Question:
"The harshest people on the Dajjal are the Banu Tamim." Is this authentic?

Answer:
It is authentic, meaning in opposing him and refuting him.
Q: Does this imply that this man is one of them?
The Shaykh: It is possible, Allah knows best. Every person of faith is against him.
Q: The Jews?
The Shaykh: They are his followers. Seventy thousand from the Jews of Isfahan will follow him from the East, and the Jews in Palestine are his people and his army. The Muslims will kill them along with the Messiah, 'Isa ibn Maryam (peace be upon him).
Q: At the end of time, the Qur'an will be taken away. Will this happen to the Sunnah as well?
The Shaykh: After the Dajjal, after a period of time, and after the sun rises from the west.
Q: And the Sunnah will still exist?
The Shaykh: There is no mention of it in the texts, but after the emergence of the Dajjal, the Qur'an will be taken away, and then the pleasant wind will come and take the souls of the believing men and women.
Q: The man who came to the Dajjal and informed him that the Prophet (peace and blessings be upon him) had informed about him, about the Dajjal, does this not indicate that the Sunnah remains until the time of the Dajjal?
The Shaykh: Yes, the Sunnah remains. The Sunnah and the Qur'an remain. The Qur'an is removed after the Dajjal, after a period of time, after the sun rises from the west.
