The time that the Fajr Prayer starts

Q 6: Is it desirable to delay the Fajr (Dawn) Prayer for half an hour or more after the Adhan (call to Prayer)? It has been said that the time of the Fajr Prayer in Egypt, which is announced by the Egyptian Meteorological Authority, is incorrect, and that is why some people delay the Adhan for fifteen minutes after the designated time. What is the ruling on that?

(Part No. 6; Page No. 127)  A: The time of the Fajr Prayer starts with the appearance of the second dawn and lasts until before the sun rises. Anyone who offers the Salah during this period has offered it in its due time, and offering the Fajr Prayer at the beginning of its time is better.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
