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 Messenger of Allah ﷺ. (Using translation from Muslim 2935)
عَنِ النَّبِيِّ ﷺ قَالَ فِي الدَّجَّالِ إِنَّ مَعَهُ مَاءً وَنَارًا فَنَارُهُ مَاءٌ بَارِدٌ وَمَاؤُهُ نَارٌ فَلَا تَهْلِكُوا قَالَ أَبُو مَسْعُودٍ وَأَنَا سَمِعْتُهُ مِنْ رَسُولِ اللهِ ﷺ
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.
عَنِ النَّبِيِّ ﷺ قَالَ فِي الدَّجَّالِ إِنَّ مَعَهُ مَاءً وَنَارًا فَنَارُهُ مَاءٌ بَارِدٌ وَمَاؤُهُ نَارٌ قَالَ أَبُو مَسْعُودٍ أَنَا سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ﷺ
