It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said: "If I reached that (point of intercourse) with my wife, I would certainly take a bath."
Musaddad transmitted this hadith through Yahya, Shu'bah, Mansur and Hilal bin Yasaf from Kharashah bin Habib, who narrated it from Ali (may Allah be pleased with him); and Sufyan narrated it through Sulayman and Mansur from Ibrahim, he from Alqamah, and he from Abdullah bin Mas'ud (may Allah be pleased with him); while in another route Abdullah bin Dawud narrated it from al-A'mash, and he from Ibrahim, but here Imam al-A'mash was in doubt about the link through Alqamah.
