Ali bin Abu Talib reported,

I was a man who discharged a great deal of prostatic fluid, so I asked the Prophet ﷺ about it.He said, "When you notice the prostatic fluid, perform ablution and wash your private part. But when you notice fluid gushing forth, then take a full bath."I mentioned this to Sufyan, and he said, "I heard it from Rukayn as well." Both of them said "fluid gushing forth."Ibn Abu Bukayr also narrated to us, saying that Zaidah narrated to them, and he too said "gushing forth."
