What did Prophet Muhammad (saw) warn his followers about Ad-Dajjal that no other prophet had?
 Narrated `Abdullah bin `Umar:                     Allah's Apostle stood up amongst the people and then praised and glorified Allah as He deserved and then he mentioned Ad-Dajjal, saying, "I warn you of him, and there was no prophet but warned his followers of him; but I will tell you something about him which no prophet has told his followers: Ad- Dajjal is one-eyed whereas Allah is not."
