The mu'adhdhin repeating the takbirs and other phrases after the imam, as happens in the two sacred mosques

Question:
In al-Masjid al-Haram and al-Masjid al-Nabawi, the mu'adhdhin repeats the takbir and the saying "Allahu has heard the one who praised Him" and the takbir after the imam during the prayer, and he raises his voice with this. This causes disturbance to the worshippers, and we think that the imam's voice should be sufficient, especially given the presence of loudspeakers. I ask your eminence to provide guidance?

Answer:
There is no harm in that; because it alerts the people, and al-Masjid al-Haram is vast, so some people may be unaware and not notice the imam's voice. Therefore, there is no harm in that alerting, and there is nothing wrong with it. al-Siddiq (may Allah be pleased with him) used to pray with the Prophet (peace and blessings be upon him) during his illness, so he would alert the people because of the Prophet's (peace and blessings be upon him) illness. Thus, the one who alerts is needed to alert the distant people so that they notice the imam's voice and follow him.
