Hawzah News Agency – Q: A person who is fasting had planned to reach his place of residence before noon adhān. But, along the way he came across an accident that delayed him, hence he did not reach his residency in time. Is his fast valid? Does he have to pay kaffārah or will performing the qaḍā’ be sufficient?
A: His fast is invalid while traveling and it is only obligatory for him to perform the qaḍā’ (of fasting) for the day in which he did not reach his place of residency, and he does not have to pay kaffārah.
