What is the expiation for a husband having intercourse with his wife during the daytime in Ramadan, and is it fasting for two months or paying a sum of money, and how much is it?

Whoever has intercourse with his spouse during the daytime in Ramadan, upon him is an ordered expiation (kaffarah murattabah): freeing a believing slave. If he is unable, then fasting two consecutive months. If he is unable, then feeding sixty poor people. This expiation suffices him, and nothing else is required of him thereafter. A Muslim must safeguard his fasting and the sanctity of Ramadan.
