The ruling on one who caresses his wife and, after sleeping, finds traces of semen on his clothes

Question : The questioner says: Honorable Shaykh, a man caressed his wife during the day in Ramadan and then slept. After he woke up, he found a sticky fluid on his clothes. What is the ruling on his fast, and what is required of him?

Answer : He owes nothing, as long as he does not know whether this semen came from caressing his wife or from a wet dream that he did not recall, because sometimes a person has a wet dream in his sleep and does not remember that he did. Also, he does not know whether what he found was semen or something else. If he does not know, then he owes nothing. Yes.
