It is narrated from Hazrat Abu Ayyub Ansari (may Allah be pleased with him) that Hazrat Ubayy bin Ka'b (may Allah be pleased with him) related this hadith to him: I asked the Holy Prophet (peace and blessings be upon him), "If a man has intercourse with his wife and does not ejaculate, what is the ruling?" The Holy Prophet (peace and blessings be upon him) said, "He should wash the part of his body that touched the woman, perform ablution, and then offer prayer."
