In Ramadan, I woke up and ate and drank because I did not hear the Fajr adhan and did not know that the time had entered. Do I have to make up the fast?

Question:
He says: Honorable Shaykh, may Allah grant you success. On one of the days of Ramadan, I woke up and ate and drank because I did not hear the Fajr adhan, and I did not know that the time had entered. When I looked at the sky, I found that the time of Fajr had entered. Is my fast considered valid?

Answer:
No. As long as it is established for you that you ate and drank after the appearance of Fajr, you must make up this day. As long as it becomes clear to you that you ate after the appearance of Fajr and drank after the appearance of Fajr, you must make up this day. Yes.
