The ruling on the adhan before the true dawn

Question:
The questioner says: In our city, the mu'adhdhin gives the second adhan about half an hour before the true dawn appears, and the prayer is established a quarter of an hour after the adhan. What is the ruling on praying in this mosque?

Answer:
There is no harm in the adhan before dawn so that people wake up; advancing the adhan before the appearance of dawn is permissible so that people wake up and prepare. However, the adhan must be given when dawn appears; the adhan must be given when dawn appears so that people know the time has entered. The first adhan is for preparation, and the second is to inform people of the entry of the time of Fajr. Therefore, one should not rely solely on the first adhan, as there is another adhan, either from him or from someone else. The Messenger (peace and blessings be upon him) said: He prays when he is told, "Have you risen?" "Have you risen?" If the adhan is at the appearance of dawn, the iqamah of the prayer depends on the state of the worshippers. If they attend quickly, they establish the prayer. If they are delayed, he waits for them until they attend, and the delay should not be excessive. Yes.
