What is required of one who drinks in Ramadan thinking that the Maghrib adhan has been called?

Question:
In the last part of this episode, she says: A person drank in Ramadan thinking that the adhan had been called, but it had not been called. What is required of him in such a case?

Answer:
If he knows that he drank before sunset, he must make it up. However, if he thought it was sunset because of apparent signs, he owes nothing. But if he drank thinking it was sunset and then the sun appeared, he must make up that day, according to the correct view held by the majority of scholars. He must make up this day, and this is the most cautious position. Some scholars do not think he must make it up because he is excused and did not do it intentionally. However, the closest and most apparent view is that he must make it up. Likewise, if he eats after Fajr thinking it is still night, but it turns out he ate during the day, he must make it up. This is the stronger position. Yes.
