The Ruling on Voluntary Prayer Between the Fajr Adhan and the Iqamah

Question:
With this matter. Is the beginning of the second dawn the adhan of the Fajr prayer? And if Abu Huban, what is the ruling on voluntary prayer between the Fajr adhan and the iqamah, other than the two rak'ahs of the Fajr prayer?

Answer:
If the mu'adhdhin adheres to the correct time and calls the adhan at the appearance of the dawn, then there is no voluntary prayer except the rawatib of the Fajr prayer only after the adhan; there is no rawatib after the Fajr prayer. However, if the mu'adhdhin calls early, because some mu'adhdhins call early since it is permissible to advance the Fajr adhan before the dawn so that people can prepare for the prayer and wake up, it is permissible to advance it before the dawn. But they say that if one calls the adhan before the dawn, there must be a second adhan after the dawn, because Bilal used to call the adhan before the dawn, and then Ibn Umm Maktum would come and call the adhan after the appearance of the dawn when he was told, "Has the dawn appeared?" "Yes, it has appeared."
So if the adhan is called before the dawn, it becomes necessary for him to call the adhan at the appearance of the dawn so as not to mislead the people. As for limiting it to the first adhan before the dawn, this results in misleading the people, and perhaps they will fast, and perhaps they will pray the Fajr prayer. Yes.
So he must either adhere to the timing and not call the adhan before the dawn, or he must call two adhans: one before the dawn and one after the appearance of the dawn, so that people know this and that.
