The World Federation One Stop Fiqh

Ruling 1635

If a person invalidates his fast by means of something unlawful – whether that thing is fundamentally unlawful, like wine or fornication, or something that has become unlawful due to a particular reason, like eating lawful food that is in a general sense harmful for him, or having intercourse with his wife when she is in the state of ḥayḍ – then in these cases, giving one kaffārah is sufficient. However, the recommended precaution is that he should give the ‘total kaffārah’, i.e. free one slave, fast for two months, and feed sixty poor people or give each one of them one mudd of wheat, barley, bread, or suchlike. In the event that all three are not possible for him, he should do the ones that are possible for him.
