One of the signs of the reappearance of Imam Mahdi (as), is the coming of a creature gone astray that misleads others by the name of “Dajjal”.  In Arabic, any liar can be called dajjal.  There are many unusual descriptions about him, but since these descriptions are mostly found in the sources of our Sunni brothers and the hadiths containing these descriptions aren’t ones that can be depended on because of their weak chains of narrators, these hadiths are unreliable.

His role in misleading others is so important that it warns us to be aware of all things that might contribute to our misguidance.

Is he human?  Is he technology?  Is he the devil himself?  Or is he/it something else other than these?  There are different viewpoints on the answer to this question.  Our advice is for all to refrain from anything that might lead to one’s misguidance and for no one to be of his adherents so that we never become one of his helpers and followers and of those deceived by him!
