What is the ruling on the transparent, viscous white fluid that soils clothes during sleep with a feeling of lust? Does it necessitate ghusl or wudu, and what is its ruling in Ramadan?

If the discharge is madhy (pre-seminal fluid), then one must wash the male organ and the affected area of the body, purify the clothes by sprinkling water on them, and then perform wudu' (ablution). If it is manly (seminal fluid), then ghusl (ritual bath) is obligatory by consensus. If you doubt whether it is manly or madhy, some scholars say you are bound by the rulings of both, while others say you may choose between them. The emission of fluid at night does not affect the fast. However, during the day: madhy does not invalidate the fast according to the preponderant opinion, while manly invalidates the fast if it is emitted through direct contact or masturbation, but it does not invalidate it through a wet dream or thought.
