Question: A woman used to get her period on a fixed date, and today was the expected day for her period. She deliberately broke her fast, but the period did not come. What is the ruling on Kaffarah (expiation)?

💫 Answer: If a woman usually gets her period on a fixed date, for example, on March 2nd, and today, March 2nd, was the expected day, she deliberately broke her fast, but the period did not come, then Kaffarah (expiation) is not obligatory. Only Qada (making up the fast) is necessary.
