O Messenger of Allah, if a man parts from his wife suddenly (during sexual intercourse) without discharging semen, what will he be required to do? The Messenger of Allah (may Allah's peace and blessings be upon him) said: It is water (seminal discharge) that makes water (ritual bath) obligatory
Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: I went to Qubā’ with the Messenger of Allah (may Allah's peace and blessings be upon him) on Monday. On reaching (the locale of) Banu Sālim, the Messenger of Allah (may Allah's peace and blessings be upon him) stood at ‘Itbān’s door and called out to him loudly. He came out dragging his lower garment. When he saw that, the Messenger of Allah (may Allah's peace and blessings be upon him) said: "We made the man hurry." ‘Itbān said: "O Messenger of Allah, if a man parts from his wife suddenly (during sexual intercourse) without discharging semen, what will he be required to do?"
