The first adhan before the adhan of Fajr and its duration

Question:
Honorable Shaykh, may Allah grant you success, is the first adhan that comes before the adhan of Fajr recommended? And if it is recommended, what is the duration between the two adhans?

Answer:
It is as long as it takes for the sleeper to wake up and for the fasting person to stop eating, meaning it serves as a reminder for the people, as long as it takes for the Muslim to perform wudu and purify himself. In it is a reminder for the people. The first adhan is a reminder for the people. Bilal used to do it in the presence of the Messenger (peace and blessings be upon him). Bilal used to call the adhan at night. And Ibn Umm Maktum used to call the adhan at the appearance of the dawn.
This is evidence for the prescription of the first adhan. But one should not rely on it alone. The first adhan is not called unless the adhan for the second one, for Fajr, will be called. Or there is another mu'adhdhin who calls the adhan at the appearance of the dawn. So that the people are not deceived into thinking that the time for prayer has entered. Yes.
