Sayyiduna Sahl bin Hunaif (may Allah be pleased with him) says: I used to face great difficulty because of madhi (pre-seminal fluid) and I used to perform ghusl (full ritual bath) very frequently because of it. One day when I asked the Messenger of Allah (peace and blessings be upon him), he said: "For you, only wudu (ablution) will suffice because of it." I said: "What should I do about what gets on my clothes?" The Messenger of Allah (peace and blessings be upon him) said: "It will suffice for you to take a handful of water and strike it on the part of the garment where you think the madhi has touched."
