Mukhtasar Muslim (Abridged) 153 — Obligation of ghusl (bath)

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrated from Umm Kulthum (may Allah be pleased with her), and she narrated from Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) that she said: A man asked the Messenger of Allah (peace and blessings be upon him), "If a man has intercourse with his wife but is unable to ejaculate, is ghusl (ritual bath) obligatory on both of them?" The Prophet (peace and blessings be upon him) replied, "I and she (meaning Umm al-Mu'mineen Aisha, may Allah be pleased with her) do this, and then we perform ghusl."
