Dajjal

 Al Dajjal a false messianic figure who will come forth before the end of time; after a reign of 40 days or 40 years, he will be destroyed by Christ or Mahdi and the world will submit to Allah.

he is described as a plump, one eyed  man with a ruddy face and curly hair and the arabic word kufr on his forehead. Al Dajjal will appear at a time of great tribulation, he will be followed by the jews and he claim to be god in Jerusalem.. he will work false miracles and most people will be decieved. At this moment will occur the second coming of Christ.

Tradition expects Al Dajjal to appear in the east, possibly in khorasan or in the west.  in the mean time  he is said to be some where in east indies on an island from which the sounds of dancing and beautiful music emanate according to sailors folk lore and the tale of sindbad the sailor.

an alternate version is linked with the greek prometheus legend, in this account , al Dajjal is bound to a rock on an island in the sea and is fed by demons.
