Qatadah reported having heard Sayyidina Anas (RA) narrate that Allah’s Messenger said, There has not been a Prophet (SAW) who has not warned his people of the one-eyed.Iiar. Know, that he will be one-eyed while your Lord is not one-eyed. It will be inscribed between his eyes Ka fa ra (Kafir).
[Bukhari 7131, Muslim 2933]
