One who drank water at the beginning of the Fajr adhan while intending to fast

The questioner:
May Allah reward you. This questioner says: If a person intended to fast from the night, and then woke up—assuming the person had intended to fast from the night—

The Shaykh:
Yes.

The questioner:
and woke up at the beginning of the Fajr adhan and drank water, what is the ruling?

The Shaykh:
The Fajr adhan differs: if the mu'adhdhin adheres to the timing and calls the adhan at the correct time, it is not permissible to drink or eat, because his adhan is a sign of the entry of the time of dawn. However, if the mu'adhdhin calls early, there is no harm in eating and drinking. The Messenger (peace and blessings be upon him) said, "Indeed, Bilal calls the adhan at night," meaning he calls early. This indicates that if the mu'adhdhin calls at the correct time, one should not eat with the adhan, like the adhan of Ibn Umm Maktum. But if he calls early, one may eat, as was the case with the adhan of Bilal (may Allah be pleased with him). Bilal's intention in advancing the adhan was to wake the people and prepare them for the suhur. Yes.
