Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) narrates: I was a person from whom madhi (pre-seminal fluid) would be discharged in abundance. I asked the Prophet (peace and blessings of Allah be upon him) about it, and he said: When you see the fluid (madhi), wash your private part and perform wudu, and when you see semen, then perform ghusl.
