(CNN)Duke University has reversed its decision to allow a Muslim call to prayer to sound from a campus chapel bell tower, school officials announced Thursday.

Plans changed because the Durham, North Carolina, school's effort to "unify was not having the intended effect," Michael Schoenfeld, vice president for public affairs and government relations, said in a statement.

"Duke remains committed to fostering an inclusive, tolerant and welcoming campus for all of its students," Schoenfeld said.

The Duke Muslim Students Association had planned to chant the call, or adhan, from the Duke Chapel bell tower. The adhan signals the beginning of the weekly prayer service. Jummah prayers have taken place in the basement of Duke Chapel for many years, the statement said.
