Abu al-Rabi‘ al-Zahrani narrated to us, Hammad narrated to us, Hisham ibn ‘Urwah narrated to us — and Abu Kurayb, Muhammad ibn al-‘Ala’, narrated to us (and the wording is his): Abu Mu‘awiyah narrated to us, Hisham narrated to us, from his father, from Abu Ayyub, from Ubayy ibn Ka‘b, who said: I asked the Messenger of Allah, peace and blessings be upon him, about a man who has contact with a woman and then becomes sexually inert (i.e., does not ejaculate). He said: "He should wash what has touched him of the woman, then perform ablution and pray."
