Hudhaifa and Abu Mas’ud got together and Hudhaifah said:
I know best what the Dajjal (Antichrist) will have with him. He will have with him a sea of water and a river of fire, and what you see as fire will be water and what you sea as water will be fire. If any of you who lives up to that time and desires water, he should drink from what he sees as fire, for he will find it water. Abu Mas’ud al-Badri said: I heard the Messenger of Allah ﷺ say in this way.

حَدَّثَنَا الْحَسَنُ بْنُ عَمْرٍو، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ رِبْعِيِّ بْنِ حِرَاشٍ، قَالَ اجْتَمَعَ حُذَيْفَةُ وَأَبُو مَسْعُودٍ فَقَالَ حُذَيْفَةُ لأَنَا بِمَا مَعَ الدَّجَّالِ أَعْلَمُ مِنْهُ إِنَّ مَعَهُ بَحْرًا مِنْ مَاءٍ وَنَهْرًا مِنْ نَارٍ فَالَّذِي تَرَوْنَ أَنَّهُ نَارٌ مَاءٌ وَالَّذِي تَرَوْنَ أَنَّهُ مَاءٌ نَارٌ فَمَنْ أَدْرَكَ ذَلِكَ مِنْكُمْ فَأَرَادَ الْمَاءَ فَلْيَشْرَبْ مِنَ الَّذِي يَرَى أَنَّهُ نَارٌ فَإِنَّهُ سَيَجِدُهُ مَاءً . قَالَ أَبُو مَسْعُودٍ الْبَدْرِيُّ هَكَذَا سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ .
