Duke University has canceled its plan to use the tower of its chapel for a weekly, amplified call to prayer for Muslims.

In a release Thursday, the North Carolina university said it reconsidered the plan. It says Muslims will instead gather on the quadrangle before heading into a room in the chapel for their weekly prayer service.

Duke spokesman Michael Schoenfeld says the previous plan to use the chapel tower didn't have the intended effect of helping to unify people on campus.

Under the canceled plan, members of the school's Muslim Students Association would have recited the call lasting about three minutes from the bell tower. The plan drew the ire of evangelist Franklin Graham, who urged Duke alumni to withhold support because of violence against Christians that he attributed to Muslims.
