The Prophet said "There has been no afflication, nor will be until the hour establishes, greater than that of the Dajjal"
The emergence of the Dajjel will be the greatest afflicion ever faced by mankind, from the creation of Adam until the last Hour, without exception. Allh will give him the ability to wreak discord, evil and dibelief on an unprecedented scale.
His tenure on Earth will be charaterised by terror, havoc and despair. He will make the truth appear as falsehood and vice versa.
