How is the time for the Fajr prayer determined?

Question:
May Allah reward you, thank you, Khalid. He says: What is the stronger position regarding the issue of the entry of the time for the Fajr prayer, where the Muslim begins performing the two rak'ahs of the Fajr prayer? And if one prays twenty minutes before the specified time between the adhan and the iqamah, has he prayed before the time and the entry of the true dawn?

Answer:
The entry of dawn is known by seeing it, by seeing the dawn, or it is known by the timing, the timing adopted in Makkah al-Mukarramah. If he sees the dawn with his own eyes or relies on the adopted calendar, his prayer is ruled valid. If the dawn appears, he prays the rawatib. Then he prays the Fajr prayer if he is alone. As for if he is praying with a congregation, he prays the rawatib and waits until the prayer is established, and he does not perform voluntary prayers other than the rawatib after the dawn appears. Yes.
