Aish bin Anas Bakri (may Allah have mercy on him) says: Sayyiduna Ali (may Allah be pleased with him), Sayyiduna Ammar (may Allah be pleased with him), and Sayyiduna Miqdad (may Allah be pleased with him) discussed the matter of madhi (pre-seminal fluid). Sayyiduna Ali (may Allah be pleased with him) said: "I experience a lot of madhi and I feel shy to ask the Messenger of Allah (peace and blessings be upon him) about it because his daughter is married to me." So he told either Sayyiduna Ammar (may Allah be pleased with him) or Sayyiduna Miqdad (may Allah be pleased with him) to ask the Messenger of Allah (peace and blessings be upon him) about it. Ata (may Allah have mercy on him) says: Aish mentioned the name of one of them, but I have forgotten; in any case, they asked, and the Messenger of Allah (peace and blessings be upon him) said: "This is madhi; he should wash it off." I asked: "Wash what?" The Messenger of Allah (peace and blessings be upon him) said: "His private part, and he should perform ablution well and sprinkle water on his private part, that is, wash it."
