Is it obligatory to make up the fast of one who drank during the Fajr adhan?

The questioner:
Please, Abdullah from al-Qway'iyah. Peace be upon you. And upon you. Peace be upon you. May Allah keep you in good, O Shaykh. I have a question. I was in Ramadan, I went to the bathroom to relieve myself, and when I came out, the mu'adhdhin was calling the adhan. I thought it was the false dawn, so I drank. Do I have to make up this day, or do I not? I asked the imam and said to him, "You are rushing the adhan." He said, "I am calling the adhan at the time specified in the calendar I have." I said, "Does the calendar you have account for the white thread the white thread?" He said, "I have a calendar that I follow."

The Shaykh:
Yes, he is right in that. So you do not eat or drink if the mu'adhdhin begins the adhan, provided he is calling it at the true dawn and according to the calendar. The saying of the Messenger (peace and blessings be upon him) And Ibn Umm Maktum used to call the adhan at the true dawn; he would not call it until it was said to him, "It is morning, it is morning." Yes. Thank you.

The questioner:
I have to make up this day.

The Shaykh:
If you delayed until after the true dawn and drank, you repeat this day, because you did not fast it completely. Yes.

The presenter:
Thank you.
