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