A man has a sexual dream and finds water but there is no place to perform Ghusl

Q: If I have a wet dream while traveling and there is water but there is no place to perform Ghusl (ritual bath following major ritual impurity), what should I do regarding Salah?

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions. You should make Ghusl if you discharge Maniy (spermatic fluid) in a wet dream. Having no place to perform Ghusl is not an excuse, as you can ask one of your friends to screen you with a mantle, for example, so that you can make Ghusl. (Part No. 5; Page No. 305) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
