Hadith 4:484
Muhammad ibn Bakr narrated to us, from Ibn Jurayj, who said: I said to ‘Amr ibn Dinar, "Is it not said regarding the one who has intercourse with his wife during Ramadan that he should complete that day and make it up?" He said, "Yes."
حدثنا محمد بن بكر عن بن جريج قال قلت لعمرو بن دينار أليس كذا يقال في الذي يصيب أهله في رمضان ليتم ذلك اليوم ويقضيه قال نعم
