The medieval Church formally banned the Muslim call to prayer on Christian territory

Evidence

Within its own boundaries, on the other hand, Christendom would not tolerate the call to prayer. Clement IV held it in particular horror; and in the early fourteenth century a canon of the universal Church forbade the Christian princes to allow this public profession of faith on their territories. That the name of Muhammad should be used in the course of calling Muslims to prayer was said to be an offence against the Divine Name and a reproach to the Christian faith. — Norman Daniel, Islam and the West, 1154
