If a muʿtakif intentionally invalidates his iʿtikāf by having sexual intercourse – be it during the day or at night – it is obligatory for him to give recompense (kaffārah). As for [intentionally invalidating one’s iʿtikāf by performing] other unlawful acts, there is no kaffārah, although the recommended precaution is that one should give kaffārah. The kaffārah for invalidating an iʿtikāf is the same as the kaffārah for invalidating a fast of the month of Ramadan – i.e.
one has the choice of fasting for sixty days or feeding sixty poor people (fuqarāʾ) – although the recommended precaution is that one should observe the sequence in giving kaffārah, meaning that one should first fast for sixty days, and if he cannot, he should then feed sixty poor people.
