Sahih al-Bukhari 2085
Narrated Samura bin Jundab:
The Prophet (ﷺ) said, "This night I dreamt that two men came and took me to a Holy land whence we 
proceeded on till we reached a river of blood, where a man was standing, and on its bank was standing 
another man with stones in his hands. The man in the middle of the river tried to come out, but the 
other threw a stone in his mouth and forced him to go back to his original place. So, whenever he tried 
to come out, the other man would throw a stone in his mouth and force him to go back to his former 
place. I asked, 'Who is this?' I was told, 'The person in the river was a Riba-eater."
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ، حَدَّثَنَا أَبُو رَجَاءٍ، عَنْ سَمُرَةَ بْنِ جُنْدُبٍ ـ رضى الله عنه ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ رَأَيْتُ اللَّيْلَةَ رَجُلَيْنِ أَتَيَانِي، فَأَخْرَجَانِي إِلَى أَرْضٍ مُقَدَّسَةٍ، فَانْطَلَقْنَا حَتَّى أَتَيْنَا عَلَى نَهَرٍ مِنْ دَمٍ فِيهِ رَجُلٌ قَائِمٌ، وَعَلَى وَسَطِ النَّهْرِ رَجُلٌ بَيْنَ يَدَيْهِ حِجَارَةٌ، فَأَقْبَلَ الرَّجُلُ الَّذِي فِي النَّهَرِ فَإِذَا أَرَادَ الرَّجُلُ أَنْ يَخْرُجَ رَمَى الرَّجُلُ بِحَجَرٍ فِي فِيهِ فَرَدَّهُ حَيْثُ كَانَ، فَجَعَلَ كُلَّمَا جَاءَ لِيَخْرُجَ رَمَى فِي فِيهِ بِحَجَرٍ، فَيَرْجِعُ كَمَا كَانَ، فَقُلْتُ مَا هَذَا فَقَالَ الَّذِي رَأَيْتَهُ فِي النَّهَرِ آكِلُ الرِّبَا ‏"‏‏.‏
