Narrated Hudhaifa: The Prophet (ﷺ) said about Ad-Dajjal that he would have water and fire with him: (what would seem to be) fire, would be cold water and (what would seem to be) water, would be fire.
حَدَّثَنَا عَبْدَانُ، أَخْبَرَنِي أَبِي، عَنْ شُعْبَةَ، عَنْ عَبْدِ الْمَلِكِ، عَنْ رِبْعِيٍّ، عَنْ حُذَيْفَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ فِي الدَّجَّالِ “ إِنَّ مَعَهُ مَاءً وَنَارًا، فَنَارُهُ مَاءٌ بَارِدٌ، وَمَاؤُهُ نَارٌ ”. قَالَ أَبُو مَسْعُودٍ أَنَا سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم.
