It is narrated from Sayyiduna Ali bin Abu Talib (may Allah be pleased with him), he says: I was a person who had a lot of madhi (pre-seminal fluid), and I felt shy to ask the Messenger of Allah (peace and blessings be upon him) about this because his daughter was married to me. So I instructed a man to ask (this issue), and he asked the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said: "Wudu must be performed due to the discharge of madhi."
