And despite complaining sometimes, that the call to prayer wakes me up - the one at dawn, particularly - you know what? I was bummed. I would really miss it if it was gone. Then I realised, upon closer inspection of the news article, that it isn't the azan at all, but the iqamat-as-salat, which comes later and signals the beginning of prayers.
I am not sure why the General Authority for Islamic Affairs and Endowments discontinued the after-the-call call, but people aren't very happy about it.
