“People complain bitterly about the cacophony from loudspeakers in the mosques,” Said Mahmoud Zaqzuq to justify his ordering a study on the possibility of a centralized or ‘unique call’ to prayer.

This would rule out mosques making their own individual calls, in keeping with a tradition that goes back to the beginning of Islam.

The minister told the daily Al Akhbar his only concern was the “search for calm and the well-being of the people, especially those looking after the sick, or pupils who need to be able to concentrate on their homework.”

Jealously guarded autonomy by the mosques inevitably produces a slight difference in timing for the call to prayer. The result is a clashing and unharmonious noise of competing calls.

Complaints come mostly from those who live near the mosques, whose sheer numbers ensure that thousands of people are affected.

Most objections focus on the muezzin s’ call at dawn, summoning the faithful to the first of Islam’s five daily prayers.

The minister is studying the installation of a network linking different mosques in the same town or district so that a single call goes out at the same time throughout the zone covered by the network.

He says this method, along with choosing the most melodious muezzin ’s voice, would enable the noise level to be controlled.

Another suggestion is to allow only the biggest mosque of an area to make the calls to bring the faithful to prayer – ruling out prayer rooms and less well- attended mosques.

The religious affairs ministry is responsible for some 90,000 mosques and prayer rooms throughout the country, including some 3,000 rooms and mosques in the crowded capital.

Imams fear the reform project will undermine Muslim liturgy. The call to prayer, instituted from the first years of Islamic preaching, was entrusted by the Prophet Muhammad to a freed black slave, Bilal, whose call remains the example for muezzin s to follow today.

A single call to prayer would not conform to Sharia (Islamic law), according to Ahmed Sayer, a professor at Al Azhar university, while his colleague Muhammad Sayed Ahmed Yassir said he feared the move could eventually lead to “canceling Friday prayers in the mosques and be satisfied with prayers put out over the radio.”

Another opponent echoed this, asking if the future rules would “limit Muslims to pray behind an imam officiating on television.”

Others questioned whether there was not “an American hand” behind the ministerial proposition. Islamists frequently accuse the US of pushing Cairo to constrain Muslim religious practices in Egypt.

Fears for the jobs of the 200,000 muezzin s working throughout Egypt have also been expressed, although the minister has promised not to sack any of the 70,000 muezzin s officially working for the state. He says they may be redeployed to other jobs within their mosques.

Those working for religious associations and private organizations appear to be the ones facing the biggest upheaval.

Opponents of the reform project question the rationale of limiting the decibel level of the morning calls.

“How can they pretend to lower the sound level of the call [to prayer] when it is aimed at awakening the faithful so they can accomplish their sacred duty?” asked Abdel Sabur Shahin, head of the Sharia faculty at Al Azhar university, the most prestigious seat of learning in the Sunni Muslim world.
