What is the ruling of the Shari'ah concerning a pregnant woman who intentionally induced vomiting to alleviate pregnancy symptoms, being unaware that doing so invalidates the fast, and has now stopped doing it? Is she required to make up the fast (qada'), or both make up the fast and offer expiation (qada' and kaffarah), or is nothing required of her?

Whoever does something that breaks the fast, being ignorant that it is a fast-breaker, his fast is not invalidated by that, according to the preponderant opinion. Therefore, the fast of a woman who intentionally induced vomiting due to her ignorance that it was a fast-breaker is valid, and she is not required to make up for it. However, if she knew of the prohibition and intentionally broke her fast, then she is only obliged to make up for it (qada'), and expiation (kaffarah) is not obligatory except for intercourse, according to the preponderant opinion.
