Swiss Ban Building of Minarets on Mosques
GENEVA — In a vote that displayed a widespread anxiety about Islam and undermined the country’s reputation for religious tolerance, the Swiss on Sunday overwhelmingly imposed a national ban on the construction of minarets, the prayer towers of mosques, in a referendum drawn up by the far right and opposed by the government.
The referendum, which passed with a clear majority of 57.5 percent of the voters and in 22 of Switzerland’s 26 cantons, was a victory for the right. The vote against was 42.5 percent. Because the ban gained a majority of votes and passed in a majority of the cantons, it will be added to the Constitution.
Firstly I don't see this happening in the US and would oppose any such action. Certainly there are many parallels here within the US with the spires on Christian churches.
It does bring up an interesting question though, how would predominantly Christian communities react if they were used for the "call to prayer" as is common in most Islamic countries and again we have a parallel because ringing of the bells and other things is common on Sunday and even other days.
The adhān (also Athaan: IPA: [ʔæˈðæːn], Azan/Ezan) (أَذَان) is the Islamic call to prayer, recited by the muezzin. The root of the word is ʼḏn, meaning "to permit", and another derivative of this word is uḏun, meaning "ear."
Adhan is called out by the muezzin in the mosque, sometimes from a minaret, five times a day summoning Muslims for mandatory (fard) prayers (salah). There is a second call known as iqama (set up) that summons Muslims to line up for the beginning of the prayers. The main purpose behind the loud pronouncement of adhan five times a day in every mosque is to make available to everyone an easily intelligible summary of Islamic belief. It is intended to bring to the mind of every believer and non-believer the substance of Islamic beliefs, or its spiritual ideology. Loudspeakers are sometimes installed on minarets for the purpose.
The adhan sums up the teachings of Islam: there is no God but Allah; Muhammad is God's Messenger; salvation is found through obedience to the Will of God, of which prayer is an important expression.
