Sayyiduna Zaid bin Khalid al-Juhani (may Allah be pleased with him) once asked Sayyiduna Uthman (may Allah be pleased with him) that if a man has intercourse with his wife but does not ejaculate, what is the ruling? He replied that he should perform ablution as he does for prayer, and wash his private part, and said that he heard the Prophet (peace and blessings be upon him) say this. The narrator says that then I asked the same question to Sayyiduna Ali, Sayyiduna Zubair, Sayyiduna Talha, and Sayyiduna Ubayy bin Ka'b (may Allah be pleased with them), and they also gave the same answer.
