What is the ruling on one who breaks his fast in Ramadan through sexual intercourse, and does he owe an expiation and making up the day?

The questioner : To what extent is it correct to say that one who breaks his fast through sexual intercourse owes an expiation and making up the day? It is known from the hadith that the expiation is required. If making up the day is valid, what is its evidence?

The Shaykh : There are narrations in which al-Hafiz Ibn Hajar al-Asqalani states that the Prophet (peace and blessings be upon him) ordered the one who broke his fast through sexual intercourse to make up a day. As Ibn Hajar himself says, the individual chains of these narrations are weak, but their collective weight gives the ruling strength. This is the basis for the opinion that making up the day is obligatory for the one who breaks his fast through sexual intercourse, in addition to the well-known severe expiation.
