Sayyiduna Ali (may Allah be pleased with him) narrates that I said to Sayyiduna Miqdad (may Allah be pleased with him) to ask the Prophet (peace and blessings be upon him) about this issue: If a man approaches his wife and madhiy (pre-seminal fluid) is discharged from him, what is the ruling? I felt shy to ask this question myself, because his daughter is married to me. So he asked this issue, and the Prophet (peace and blessings be upon him) said: "Such a person should wash his private part and perform wudu."
