Musnad Abu Ya'la al-Mawsili 42:263

Zuhayr narrated to us, Abu ‘Amir narrated to us, from Zuhayr, from Sharik, from ‘Abd al-Rahman ibn Abi Sa‘id, from his father, who said: We went out with the Prophet, may Allah bless him and grant him peace, on Monday to Quba’. He passed by us at Banu Salim, and the Messenger of Allah, may Allah bless him and grant him peace, stopped at the door of Ibn ‘Utban and called out to him while he was upon his wife’s belly. He came out dragging his lower garment. When he saw him, he said: "The man has been hurried." Ibn ‘Utban said: "O Messenger of Allah, what do you see regarding a man if he is hurried away from his wife and does not ejaculate? What is upon him?" He said: "Verily, the water is from the water."
