Duke University plans to sound a Muslim call to prayer from the university's chapel bell tower beginning this Friday, and the decision has rippled through social media, sparking some outcry.

A male student from the Duke Muslim Students Association will chant the call, or adhan, from tower, signalling the beginning of the weekly prayer service, or jummah, CNN reported. The call will last for three minutes and will be "moderately amplified." It will repeat every Friday at 1 p.m.

The North Carolina university was established with help from the Methodist church, and some see using the chapel for Muslim prayer, particularly in light of the recent terror attack in Paris, as an affront to Christians.

Franklin Graham, son of famed evangelist Billy Graham, urged donors to fight back against the university's decision.

Allowing the call from the chapel is meant to show "commitment to religious pluralism that is at the heart of Duke's mission," explained Christy Lohr Sapp, an associate dean for religious life at Duke, in an editorial for the News & Observer:

Duke has more than 700 Muslim students, faculty and staff, but some people on social media voiced concern that Duke was allowing these individuals to have privileges not given to others:

Duke University is going to start airing Muslim prayer over speakers every Friday, do they display the 10 commandments on campus also? — Jami 🦅 (@Jami_USA) January 14, 2015

I wonder how Duke or atheist would feel if Christians wanted to recite the lords prayer once a week?... http://t.co/J09Ojp5ScA — Bill LuMaye Show (@BillLuMaye) January 14, 2015

Duke posted an FAQ about the call that attempted to clear up any misconceptions, noting that none of the chapel's other religious services are being taken away:

The addition of the adhan was in the works months ago, well before the Charlie Hebdo shooting, according to Imam Adeel Zeb, a Muslim chaplain at Duke who spoke with the Christian Science Monitor.

"This is not about politics," Zeb said. "This is part of Duke's mission to promote religious diversity on campus."

WRAL notes that in many majority Muslim countries, the adhan is sounded from mosques, television and radio stations five times a day. Full sermons are broadcast on Fridays.
