Usually, the musical chant that ushers Muslims into their house of worship for prayer is prohibited under city noise bylaws. But across Canada, cities are allowing the call, or adhan, during the COVID-19 crisis, during the Muslim holy month of Ramadan.

The Islamic call to prayer, adhan, means "to listen," and it summons Muslims for obligatory prayer, which takes place five times a day and is meant to bring people together.

An Edmonton mosque has developed an app that provides accurate, real-time prayer notifications five times a day.
