I often feel bad when I write about Odin because he's a deity that is actively worshiped by a number of good-mannered people (although in America many support the wars or the soldiers fighting the wars and have charities for them thinking they're doing their god's work but anyway...). At the same time, however, there are things about Odin that cannot be ignored.
I want to reiterate this one point I have: For all we know, Arabs of Muhammad's (saaws) time did not have interaction with Germans or Scandinavians and so the concept of Dajjal is unique and has no cultural precursor. Even if pre-Islamic Arabs did have connections to people who venerate Odin, it would have been minor contact i.e. trade, and it makes no sense for an Antichrist figure to come from some foreign deity insignificant to Arabs rather than something that had existed among the Arabs or Judeo-Christian tradition.
For those who don't know what the Dajjal is, in sum, he is the Antichrist at the End of Times who is one-eyed, will be a massive deceiver (the best...dajjal means deceiver) who manipulates with magick, illusions and mind control, who has supernatural powers, a love of violence and warfare, an anger management problem and has a massive following of women (I think Christian tradition adds he's a seducer of women). He will start out by claiming to be human and eventually from there will proclaim his godhead and demand worship. He will be able to wander into every home and part of his deception is that he will have jinn (spirits, creatures, whatever you want to call them) who will shapeshift into dead relatives (like ghosts) in order to bring people to his side (at that time there will be much chaos and desperation). There will be a great war and eventually he will be killed by the true messiah (Isa aka Jesus) with a spear. Yes, a spear.
For those who know Odin, much of those qualities match his character. The one-eye situation with Dajjal is a little different than Odin's but that can be explained away by one or the other tradition having an error concerning the nature of his blindness because the similarities are otherwise too profound. To emphasize my above points, here are some of Odin's 102 (some say 200) names:
Atriðr, Atriði - Attacking rider, 'At-Rider'
Auðun - Friend of wealth
Báleygr - Flaming Eye

Why would someone worship a deceiver? How do you know he is not deceiving you when he is openly admitted to having such a nature...and not only that but openly is addressed as being evil? I don't understand that, especially when he's a god of the elite and historically, a god feared by soldiers for a variety of reasons (he could give madness in battle, or cause an enemy to win etc.) and so was not very "down to earth" with men except in his wanderings.
Army Praises ODIN
The Dajjal is going to cause mass starvation and storms and things and then wait for people to come to him in order to provide relief. Then engage in massive warfare. Collecting the souls of the dead could also be metaphorical and not literal i.e. when you die you will be judged with whom you followed and died for. If you died for a deceiver that is your own price.
I want to conclude that I'm only emphasizing this because of the striking similarities between Odin and traditions concerning the Dajjal. If Odin had none I wouldn't even mention anything relating to this. I also don't put these kind of disclaimers when I talk about Horus because he is embraced by occultists and the like who are actively trying to further the Aeon of Horus and other nefarious things.
