What is obligatory for one who finds wetness upon waking from sleep?

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: If I wake up from sleep and I have had a wet dream, is this considered semen or pre-seminal fluid? And what is obligatory in this case?

Answer:
If you find the wetness, if you feel that you had a wet dream and you find the wetness, then this is major ritual impurity without a doubt. Likewise, if you find the wetness after sleeping and you do not remember a wet dream, then it is obligatory for you to perform the full ritual bath. This is based on the saying of the Messenger (peace and blessings be upon him): The water for the full ritual bath is required by the presence of the water from the wet dream, because one may have a wet dream and not feel it, for sleep is heavy. A person may have a wet dream and semen may come out of him, and he does not know; he finds its trace when he wakes up. Yes, so whoever wakes up and finds wetness, he performs the full ritual bath, because this is major ritual impurity of which he is not aware. Yes.
