Doubting that a man has had a sexual dream, but no traces of Maniy

Q: What is the ruling on a person who wakes up and then doubts that he had a wet dream but when he examines his underwear, he does not find Maniy (spermatic fluid)?

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions.The basic rule is that no Ghusl (ritual bath following major ritual impurity) is required of him (unless there is a clear evidence to prove that it is required), because what is certain cannot be overruled by what is doubtful.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
