Question
A person woke up late for Suhoor, looked at the clock at the moment of waking, and understood from the glance that the time for fasting had not yet entered, so he drank and gave his wife and child to drink, and they drank as well. Then it became clear to him afterward that he had drunk two or three minutes after the time for fasting had begun. Does he have to make up a day instead of it while the night is still ongoing, and what is the ruling on this according to the Shafi'i school since the husband is of the Shafi'i school?
Answer
I say, and with God's guidance: His fast is invalid whether it is obligatory or voluntary, and he must make up this day due to its invalidation by mistake, and he should refrain from eating if it is in Ramadan. In the case of voluntary fasting, making up is sufficient. This is according to the Hanafi school, and God knows best.
