Allah's Apostle very often used to ask his companions, "Did anyone of you see a dream?" So dreams would be narrated to him by those whom Allah wished to tell. One morning the Prophet said, "Last night two persons came to me (in a dream) and woke me up and said to me, 'Proceed!' I set out with them and we came across a man lying down, and behold, another man was standing over his head, holding a big rock. Behold, he was throwing the rock at the man's head, injuring it. The rock rolled away and the thrower followed it and took it back. By the time he reached the man, his head returned to the normal state. The thrower then did the same as he had done before. I said to my two companions, 'Subhan Allah! Who are these two persons?' They said, 'Proceed!'

I asked them, 'Who are these?' They said to me, 'Proceed!' And so we proceeded and came across a river." I think he said, ".... red like blood." The Prophet added, "And behold, in the river there was a man swimming, and on the bank there was a man who had collected many stones. Behold, while the other man was swimming, he went near him. The former opened his mouth and the latter (on the bank) threw a stone into his mouth whereupon he went swimming again. He returned and every time the performance was repeated. I asked my two companions, 'Who are these (two) persons?' They replied, 'Proceed! Proceed!' And we proceeded till we came to a ...
