"Dajjal is well-built with his hands tied to his neck and having iron shackles between his two legs up to the ankles."
- Prophet Muhammad

If it isn't suspicious, why would they hide it?

"Dajjal will command the sky to rain, and it will rain, and it will command the earth to bring forth vegetation and it will do so. And part of its trial will be that it will pass by a clan and they will disbelieve in it, so all their flocks will perish and none will be left."
- Prophet Muhammad
