During the Friday prayer (Salat Al Jumu'ah), there are two adhans; the first is to call the people to the mosque, the second is said before the Imam
begins the khutbah (sermon). Just before the prayers start, someone amongst the praying people recites the iqama as in all prayers. The basis for this
is that at the time of the Caliph Umar he ordered 2 adhans to be made, the first of which was to be made in the marketplace to inform the people that
the Friday prayer was soon to begin, and the second adhan would be the regular one held in the mosque. Not all Sunnis prefer two adhans as the need
for warning the people of the impending time for prayer is no longer essential now that the times for prayers are well known.

Azaan/Adhan is the muslim call for prayer used 5 times a day for informing people that it's time for prayer.
It was used in the old days to let people know that it was time for prayer. Back then, they didn't have loudspeakers, TVs, watches, radios. The only
way people could know about the prayer was when the Muazzin stood on the minaret and recited those words in a son tune.
The tradition is still used today even though no one really needs to know the time. People either have watches, radio, tv, internet, cellphones, etc.
that tell them time of prayer. In this modern age, Azaan is not required but people still do it because it's tradition.
While I agree that people should have their rights to follow their tradition, religion, culture, etc. I do not agree with the mosque here.
The right course of action would be to find out in what radius can the azaan be heard? Then everyone who lives in that radius should be asked if they
are ok with it. If even 1 person is not ok with the azaan being recited on the loudspeaker, then they should not do it. It's not about muslim country
or christian neighborhood. Its about people respecting other people's opinion especially when that other person pays to live in that area.
I do not see why they need to recite it on the loudspeaker. I have seen many mosques who turn off their loudspeakers and recite the azaan so it can be
heard in the mosque only.
I am muslim btw.
