The reason for the multiple adhan in the Fajr prayer

Question:
A questioner asks: Why was there more than one adhan for the Fajr prayer in the time of the Messenger of Allah (peace and blessings be upon him)? The adhan of Bilal ibn Rabah and Ibn Umm Maktum (may Allah be pleased with them both).

Answer:
Bilal’s adhan is called at night, meaning before the dawn breaks, in order to wake up the sleepers and alert those who are engaged in night prayer so that they can prepare for the Fajr prayer. Then the adhan is called for Ibn Umm Maktum when the dawn breaks. He was a blind man who would not call the adhan until he was told, “It is morning, it is morning.” The difference between the two is that Bilal’s adhan is before the dawn, and Ibn Umm Maktum’s adhan is at the dawn. From this, the scholars said that whoever calls the adhan at night must call the adhan at the dawn. So if he calls it early to wake people up, he must call it at the dawn so that they know that the first adhan was at night and they do not pray Fajr; rather, they pray upon the second adhan. Yes.
