`Sayyiduna Ali (may Allah be pleased with him) says that I was a man who had a lot of madhiy (pre-seminal fluid), and I felt shy to ask the Messenger of Allah (peace and blessings of Allah be upon him) because his daughter was married to me, so I asked Sayyiduna Miqdad bin Aswad (may Allah be pleased with him) to ask (on my behalf). He asked, and the Prophet (peace and blessings of Allah be upon him) said: He should wash his private part and perform wudu (ablution).
