Emission Of Mathi During Sleep
If you’re certain about mani, ghusl is compulsory before salah. If you’re certain about mathi, no ghusl is required. If you’re not certain , but you know that it was one of the above, it better to make ghusl before salah. If there’s no physical evidence of either , then you’re not required to do anything.
