If the mu'adhdhin makes a mistake in Ramadan and calls the adhan a few minutes before Maghrib, and the people break their fast, are they required to make up that day?

Question:
He says: Honorable Shaykh, may Allah grant you success. If the mu'adhdhin calls the adhan about seven minutes before the time for the Maghrib adhan, and some people break their fast, are they required to repeat the fast for that day?

Answer:
Yes, without a doubt; because they did not complete the day. They broke their fast before completing the day, so they are required to make it up. This occurred during the time of the Companions. It was a cloudy day, and the mu'adhdhin called the adhan, then the sun emerged from the clouds, so they issued a ruling that making up the fast is obligatory.
