What is the ruling on one who wakes up and finds moisture on his garment?

Question:
What?

Answer:
He says: If a person wakes up from sleep and finds moisture on his garment or on his body, this is wet dreams, and he has to perform ghusl. He has to perform ghusl. The Prophet (peace and blessings be upon him) said: "Water is from water." Water means ghusl. The emission of semen, and the sleeper does not feel it; he may have a wet dream without knowing. But if he finds the trace, this is evidence that he had a wet dream, so he performs ghusl.
