Sahih Bukhari Volume 9, Book 92, Hadith 7129

حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا إِبْرَاهِيمُ، عَنْ صَالِحٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ ـ رضى الله عنهما ـ قَالَ قَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي النَّاسِ فَأَثْنَى عَلَى اللَّهِ بِمَا هُوَ أَهْلُهُ ثُمَّ ذَكَرَ الدَّجَّالَ فَقَالَ ‏"‏ إِنِّي لأُنْذِرُكُمُوهُ، وَمَا مِنْ نَبِيٍّ إِلاَّ وَقَدْ أَنْذَرَهُ قَوْمَهُ، وَلَكِنِّي سَأَقُولُ لَكُمْ فِيهِ قَوْلاً لَمْ يَقُلْهُ نَبِيٌّ لِقَوْمِهِ، إِنَّهُ أَعْوَرُ وَإِنَّ اللَّهَ لَيْسَ بِأَعْوَرَ

Narrated By 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."
