What are the consequences of the adhan being called before its time has entered?

Question:
It was stated in the Tawhid magazine in one of its issues published last year that the time for the Fajr prayer does not begin until twenty minutes after the adhan, and therefore it is not permissible to pray the sunnah before this time, and some people have permitted themselves to eat and drink until that time?

Answer:
This varies according to the countries. If it is known that the adhan is called early in the country, and that the one calling the adhan calls it before the dawn, then this is an error. It does not prohibit food for the fasting person if it is known that the mu'adhdhin called early and that he called before the dawn. Therefore, food is not prohibited, and prayer is not permissible. However, this is not specific to Egypt, nor to other than Egypt; this is in every country.
If a person knows in his country, in his village, or in his place, or in his tribe, or in the desert where he is, that this mu'adhdhin called before the dawn, then food is not prohibited for one who intends to fast. He eats and drinks until the dawn appears, and prayer is not permissible for him, neither the obligatory prayer nor the rawatib. The rawatib is not valid before the appearance of the dawn.
As for if it is known that the dawn has appeared, he must abstain from food and drink, and the Fajr prayer and its rawatib become permissible. This is not specific to Egypt, nor to other than Egypt, but all countries follow this pattern. The mu'adhdhin must seek to determine the dawn and call the adhan upon the appearance of the dawn. It is not permissible for a Muslim to eat after the appearance of the dawn, even if the adhan has not been called, and even if he has not heard the adhan. If he knows that the dawn has appeared, he has no right to eat while he intends to fast, especially the obligatory fast like Ramadan. He has no right to eat after he has known the appearance of the dawn, even if the mu'adhdhin has not called, and even if the mu'adhdhin is sleeping and has not called.
The criterion is the dawn. If the adhan is called before the dawn, and it is known that it was called before the dawn, then its adhan does not prohibit eating and drinking for the fasting person, nor does it make prayer permissible. Rather, his adhan is an error and not in its proper place. Therefore, food is not prohibited for the fasting person, and it does not permit the Fajr prayer. The Fajr prayer is after the appearance of the dawn, and fasting is in the daytime, not in the night. If his adhan is early, then his adhan is not in its proper place, unless he intended the first adhan; in that case, there is no harm. However, he cannot rely on it alone; no, he cannot rely on it alone. Rather, the adhan is called after the appearance of the dawn.

Question: Is the dawn known by the word of Allah (Glorified and Exalted is He) : [al-Baqarah:187]? Does the Muslim rely on this, or does he rely on the adhan of the mu'adhdhin?

Answer: He relies on the adhan if the mu'adhdhin is trustworthy. He relies on it. The mu'adhdhin seeks to determine the time and takes care, and does not call the adhan except when the dawn has appeared. The Muslims rely on the adhan. In the time of the Prophet (peace and blessings be upon him), they relied on the adhan.
