Volume 3, Book 34, Number 298:
Narrated Samura bin Jundab:
The Prophet 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 stand –
ing 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.”
