کتاب الفتن · نُعیم بن حماد

Narrated Ibn Umar: (Later on) Allah's Messenger (ﷺ) (once again) went along with Ubai bin Ka'b to the garden of date-palms where Ibn Saiyad was staying. When the Prophet entered the garden, he started hiding himself behind the trunks of the date-palms as he wanted to hear something from Ibn Saiyad before the latter could see him. Ibn Saiyad was lying in his bed, covered with a velvet sheet from where his murmurs were heard. Ibn Saiyad's mother saw the Prophet (ﷺ) while he was hiding himself behind the trunks of the date-palms. She addressed Ibn Saiyad, "O Saf!" (And this was his name). Ibn Saiyad got up. The Prophet (ﷺ) said, "Had this woman let him to himself, he would have revealed the reality of his case." Then the Prophet (ﷺ) got up amongst the people, glorifying Allah as He deserves, he mentioned Ad-Dajjal, saying, "I warn you about him (i.e. Ad-Dajjal) and there is no prophet who did not warn his nation about him, and Noah warned his nation about him, but I tell you a statement which no prophet informed his nation of. You should understand that he is a one-eyed man and Allah is not one-eyed

Az-Zuhri narrated from Salim from Ibn 'Umar who said:"The Messengers of Allah(s.a.w)stood among the people,he praised Allah as is due to Him, then he mentioned the Dajjal and he said: 'Indeed I warn you of him. There has not been a Prophet except that he warned his people, and Nuh indeed warned his people – but I am to say something about him that no Prophet has said to his people: You should know that he is one-eyed, and Allah is certainly not one-eyed.'” Az-Zuhri said: “ `Umar bin Thabit Al-Ansari informed me that some of the Companions of the Prophet(s.a.w) informed him, that one day, the Prophet(s.a.w) was cautioning them against Fitnah and he said: 'You must know that not one of you will ever see his Lord until he dies. And indeed, he(the Dajjal) has “Kafir” written between his eyes; everyone who is averse to his behavior shall read it.'” (Sahih)
