The ruling on the adhan for Fajr before the time enters and praying after it

Question:
Honorable Shaykh, may Allah grant you success, regarding the permissibility of the Fajr adhan after midnight, before the time enters. The question is: Is it permissible to pray the Fajr prayer before the time enters, after the adhan?

Answer:
No, it is not permissible, it is not permissible, it is not permissible, except after [the time enters]. As for the one who calls the adhan before Fajr, they say he must call the second adhan so as not to harm the people, or there should be another mu'adhdhin who calls the adhan after Fajr, as was the case with Bilal and Abdullah ibn Umm Maktum (may Allah be pleased with them both).
It is not limited to the first adhan so as not to mislead the people. The first adhan is called so that they may wake up, and so that those who perform the tahajjud prayer may do so. May Allah help us. The tahajjud prayer is also lowered, and one prepares for Fajr so that he does not think the night is still remaining. The one who wins should make his wudu and change his clothes. This first adhan is for that purpose. As for the prayer, it is upon the second adhan. Fasting is upon the second adhan.
