All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
A person who deliberately broke the fast in Ramadan is obliged to make it up and expiate for it if one broke the fast because of having sexual intercourse with his wife. However, if one broke the fast for other reasons, then he is only obliged to make up for the day he broke the fast, according to the most preponderant opinion of the scholars and he is not obliged to expiate for it.
The expiation for a person who broke the fast because of sexual intercourse with his wife is to free a slave, and whoever is unable to do this, he is obliged to fast two consecutive months, so much so that if he breaks the fast one day without a valid reason, he is obliged to fast again from the beginning. However, if he breaks the fast for a sound reason, because of sickness, or fainting, for instance and the like, then in this case he does not start anew, but he should resume from where he stopped fasting, as the continuity of fasting is not interrupted due to the above reasons. Nonetheless, if one is unable to fast because it is very difficult for him to fast two consecutive months, then he is obliged to feed sixty poor persons [on each day he broke the fast due to having sexual intercourse with his wife].
Allah Knows best.
