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."
