Sahih al-Bukhari 91:18
Narrated `Abdullah bin `Umar:
Allah's Messenger (ﷺ) said, "I saw myself (in a dream) near the Ka`ba last night, and I saw a man with whitish red complexion, the best you may see amongst men of that complexion having long hair reaching his earlobes which was the best hair of its sort, and he had combed his hair and water was dropping from it, and he was performing the Tawaf around the Ka`ba while he was leaning on two men or on the shoulders of two men. I asked, 'Who is this man?' Somebody replied, '(He is) Messiah, son of Mary.' Then I saw another man with very curly hair, blind in the right eye which looked like a protruding out grape. I asked, 'Who is this?' Somebody replied, '(He is) Messiah, Ad-Dajjal.'"

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " أُرَانِي اللَّيْلَةَ عِنْدَ الْكَعْبَةِ فَرَأَيْتُ رَجُلاً آدَمَ كَأَحْسَنِ مَا أَنْتَ رَاءٍ مِنْ أُدْمِ الرِّجَالِ، لَهُ لِمَّةٌ كَأَحْسَنِ مَا أَنْتَ رَاءٍ مِنَ اللِّمَمِ، قَدْ رَجَّلَهَا تَقْطُرُ مَاءً، مُتَّكِئًا عَلَى رَجُلَيْنِ ـ أَوْ عَلَى عَوَاتِقِ رَجُلَيْنِ ـ يَطُوفُ بِالْبَيْتِ، فَسَأَلْتُ مَنْ هَذَا فَقِيلَ الْمَسِيحُ ابْنُ مَرْيَمَ. ثُمَّ إِذَا أَنَا بِرَجُلٍ جَعْدٍ قَطَطٍ أَعْوَرِ الْعَيْنِ الْيُمْنَى كَأَنَّهَا عِنَبَةٌ طَافِيَةٌ، فَسَأَلْتُ مَنْ هَذَا فَقِيلَ الْمَسِيحُ الدَّجَّالُ ".
