Hudhaifa reported Allah's Messenger (ﷺ) as saying:
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا شُعْبَةُ ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، - وَاللَّفْظُ لَهُ - حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ ، حَدَّثَنَا شُعْبَةُ ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ ، عَنْ رِبْعِيِّ بْنِ، حِرَاشٍ عَنْ حُذَيْفَةَ ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ فِي الدَّجَّالِ " إِنَّ مَعَهُ مَاءً وَنَارًا فَنَارُهُ مَاءٌ بَارِدٌ وَمَاؤُهُ نَارٌ فَلاَ تَهْلِكُوا " . قَالَ أَبُو مَسْعُودٍ وَأَنَا سَمِعْتُهُ مِنْ، رَسُولِ اللَّهِ صلى الله عليه وسلم .
the Dajjal would have with him water and fire and his fire would have the effect of cold water and his water would have the effect of fire, so don't put yourself to ruin. Abu Mas'ud reported: I also heard it from Allah's Messenger (ﷺ).
