Dr. Zakir: If a person has a wet dream during the day while having a fast, maybe he offers Fajr Salaah and he sleeps and he has a wet dream, it is involuntary. A person has a wet dream, even if he ejaculates, its involuntary, he's not to be blamed for that. So in this case, because it's unintentional, surely it will not break the fast and he can complete the fast and the thing that is advised to him is that he should have a Ghusl, a bath, as soon as possible so that he can offer the Salaah.
Yusuf Chambers: Ah.. that's excellent, I think that's self explanatory, thank you for that
