A physician told a patient that fasting is harmful for his health. However, after a few years, he realized that fasting was not harmful for him and the physician was wrong in excusing him from fasting. Does he have to pay kaffārah in addition to performing qaḍā’?
Someone with a strong excuse doubted — 50% probability — that fasting was not obligatory for him, so he did not fast. Later it became clear to him that fasting was obligatory for him at that time. What is the ruling in respect of performing the qaḍā’ and paying kaffārah?
