عَبْد الله بْنَ عُمَرَ رضى الله عنهما قَالَ قَالَ رَسُولُ اللَّهِ صلّى الله عليه وسلّم: بَيْنَا أَنَا نَائِمٌ رَأَيْتُنِي أَطُوفُ بِالْكَعْبَةِ فَإِذَا رَجُلٌ آدَمُ سَبْطُ الشَّعَرِ بَيْنَ رَجُلَيْنٍ يَنْطِفُ رَأْسُهُ مَاءً، فَقُلْتُ مَنْ هَذَا قَالُوا ابْنُ مَرْيَمَ. فَذَهَبْتُ أَلْتَفِتُ فَإِذَا رَجُلٌ أَحْمَرُ جَسِيمٌ جَعْدُ الرَّأْسِ أَعْوَرُ الْعَيْنِ الْيُمْنَى، كَأَنَّ عَيْنَهُ عِنَبَةٌ طَافِيَةٌ، قُلْتُ مَنْ هَذَا قَالُوا هَذَا الدَّجَّالُ. أَقْرَبُ النَّاسِ بِهِ شَبَهًا ابْنُ قَطَنٍ.
It is narrated by Hazrat Abdullah bin Umarra that, “Allah’s Messengersa said, ‘While I was sleeping, I saw myself performing the tawaf of the Kaaba. Behold, there I saw a whitish-red lank-haired man [holding himself] between two men with water dropping from his hair. I asked, ‘Who is this?’ The people replied, ‘He is the son of Mary.’ Then I turned my face to see another man with a red complexion, a big body, curly hair, and blind in the right eye which looked like a protruding out grape. I asked, ‘Who is he?’ They replied, ‘He is Ad-Dajjal;’ Ibn Qatan resembles him more than anybody else among the people.’’”
