Sahih Muslim Book - 52, Hadith - 7370

حَدَّثَنَا عَلِىُّ بْنُ حُجْرٍ حَدَّثَنَا شُعَيْبُ بْنُ صَفْوَانَ عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ عَنْ رِبْعِىِّ بْنِ حِرَاشٍ عَنْ عُقْبَةَ بْنِ عَمْرٍو أَبِى مَسْعُودٍ الأَنْصَارِىِّ قَالَ انْطَلَقْتُ مَعَهُ إِلَى حُذَيْفَةَ بْنِ الْيَمَانِ فَقَالَ لَهُ عُقْبَةُ حَدِّثْنِى مَا سَمِعْتَ مِنْ رَسُولِ اللَّهِ -صلى الله عليه وسلم- فِى الدَّجَّالِ. قَالَ « إِنَّ الدَّجَّالَ يَخْرُجُ وَإِنَّ مَعَهُ مَاءً وَنَارًا فَأَمَّا الَّذِى يَرَاهُ النَّاسُ مَاءً فَنَارٌ تُحْرِقُ وَأَمَّا الَّذِى يَرَاهُ النَّاسُ نَارًا فَمَاءٌ بَارِدٌ عَذْبٌ فَمَنْ أَدْرَكَ ذَلِكَ مِنْكُمْ فَلْيَقَعْ فِى الَّذِى يَرَاهُ نَارًا فَإِنَّهُ مَاءٌ عَذْبٌ طَيِّبٌ ».فَقَالَ عُقْبَةُ وَأَنَا قَدْ سَمِعْتُهُ تَصْدِيقًا لِحُذَيْفَةَ.

It was narrated that Rib'i bin Hirash said: "I went with 'Uqbah bin 'Amr Abu Mas'ud Al-Ansari to Hudhaifah bin Al-Yaman. 'Uqbah said to him: 'Tell me what you heard from the Messenger of Allah (s.a.w) about the Dajjal.' He said: (The Prophet (s.a.w) said :) 'The Dajjal will emerge, and he will have with him water and fire. As for that which the people will think is water, it will be burning fire, and as for that which the people will think is fire, it will be sweet, cool water. Whoever among you sees that, let him plunge into that which he thinks is fire, for it is sweet, cool water."' 'Uqbah said: "I also heard it" - confirming what Hudhaifah said.
