Sahih al-Bukhari 3337Book 60, Hadith 12
حَدَّثَنَا عَبْدَانُ، أَخْبَرَنَا عَبْدُ اللَّهِ، عَنْ يُونُسَ، عَنِ الزُّهْرِيِّ، قَالَ سَالِمٌ وَقَالَ ابْنُ عُمَرَ ـ رضى الله عنهما 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 أَنْذَرَهُ قَوْمَهُ، لَقَدْ أَنْذَرَ نُوحٌ قَوْمَهُ، وَلَكِنِّي أَقُولُ لَكُمْ فِيهِ قَوْلاً لَمْ يَقُلْهُ نَبِيٌّ لِقَوْمِهِ، تَعْلَمُونَ أَنَّهُ أَعْوَرُ، وَأَنَّ اللَّهَ لَيْسَ بِأَعْوَرَ ".
Once Allah's Messenger (ﷺ) 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."
