What is the Surah or Ayah that is protection from Al Dajjal?

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

Al Dajjal will constitute a great trial for all Muslims.  May Allah Protect us all from its temptations.

The only way to get saved from those trials is to seek refuge with Allah supplicating Him ardently for protection.  Also, one should recite the first ten Ayah (verses) of Surah Al Kahf.  The Prophet (Sallallahu Alaihi wa Sallam) said: "Whoever recites ten verses from the beginning of Surah Al Kahf, Allah Protects him from Dajjal."

Allah knows best.
