Narrated Ibn `Umar: Once Allah's Apostle stood amongst the people, glorified and praised Allah as He deserved and then mentioned the Dajjal saying, l warn you against him (i.e. the Dajjal) and there was no prophet but warned his nation against him. No doubt, Noah warned his nation against him but I tell you about him something of which no prophet told his nation before me. You should know that he is one-eyed, and Allah is not one-eyed.
