Aren’t loud speakers against their religion ? LOL
First time I ever heard the call was around 4am upon landing in Jordan after an overnight flight and I had just collapsed into my hotel bed. It droned on for about 5 to 10 minutes. Definitely a loudspeaker and not a human. My theory is Islam is mostly a grumpy religion because of this first crack of the dawn wake up call. It’s every day and there is no respite unless you get out of range.
