Sayyiduna Miqdad bin Aswad (may Allah be pleased with him) narrates that I asked the Messenger of Allah (peace and blessings be upon him) about a man who approaches his wife and pre-seminal fluid (madhi) is discharged. The Messenger of Allah (peace and blessings be upon him) said: When any of you experiences such a condition, he should wash his private part. The narrator says: What the Messenger of Allah (peace and blessings be upon him) meant was that he should wash his private part and perform ablution.

Sayyiduna Ali (may Allah be pleased with him) narrates that I used to have a lot of madhi (pre-seminal fluid), but I felt shy to ask the Messenger of Allah (peace and blessings be upon him), because his daughter (Sayyidah Fatimah al-Zahra, may Allah be pleased with her) was married to me. So I told a man (Miqdad bin Aswad, may Allah be pleased with him). He asked the Prophet (peace and blessings be upon him), and he said: Wudu is necessary because of it.

Sayyiduna Abdullah bin Sa’d (may Allah be pleased with him) narrates: I asked the Messenger of Allah (peace and blessings be upon him), and he said: The fluid that comes out after semen is called madhiy, and every young man experiences madhiy. In such a situation, you should wash your private part and testicles, and perform ablution as you do for prayer.
