Musannaf Ibn Abi Shaybah 8227 — A man who feels wetness while praying

Muhammad bin Abd al-Rahman said: I asked Sa'id bin al-Musayyib, Urwah bin al-Zubayr, Sulayman bin Yasar and Abu Salamah bin Abd al-Rahman about a man from whom prostatic fluid (madhi) comes out. All of them said: Treat it like a boil; whatever you see of it, wash it, and whatever overcomes you, leave it.
