about the ruling on the takbir (proclaiming the greatness of Allah) one hour or half an hour before the Fajr adhan?

Question:
He asks about the ruling on the takbir one hour or half an hour before the Fajr adhan.

Answer:
Proclaiming the takbir before the adhan for Fajr is a bid'ah (religious innovation). Reciting the salawat (blessings) upon the Prophet (peace and blessings be upon him) and raising one's voice with it on the minbars and in the loudspeakers. These are among the newly introduced innovations for which Allah does not grant any authority.
Yes, the takbir is a remembrance of Allah and is good, so it is the best of remembrance, and it is a word of tawhid (the oneness of Allah). But making it in this form, specifying it for this time, and preceding the adhan with it, this is a bid'ah. If a person remembers Allah between himself and his own self, and increases in the remembrance of Allah, that is a good thing. But utilizing it at a specific time, yes, and performing it in a specific manner, but there is no evidence for it. So what is said before the adhan from the adhkar (remembrances), this is an innovation, and it must be abandoned.
