Especially where they now have these newfangled things called “watches”. Let’s admit that the call is a relic of the middle ages, much as the Christian church bells were. Just as loud church bells are no longer necessary to call people to church, so the Muslim call is also no longer necessary. There should be apps for that.
Yes, I’m sure it’s a relic of a previous era.
Maybe Muslims want to let everyone know they are here, maybe hoping they will get some converts, who didn’t know there was a Muslim community in their town????
