There are two other relevant edicts against non-Muslims in Muslim lands:
- Prohibition against calling the prayer by a bell or a some kind of a Gong (Nakos).
- Prohibition of Christians and Jews against raising their voices at prayer times.
In fact, one reason why the semantron is used in the Middle East as a Christian call to prayer is because Muslims banned church bells! (In some Muslim societies, the semantron was banned as well. One Umayyad caliph destroyed a church after hearing the semantron.)
Yes, eleven centuries before loudspeakers were invented, Muslims banned Jews and Christians from doing anything related to prayer that would be considered offensive to sensitive Muslim ears.
Now, Muslims are crying about how discriminatory it is to demand that they lower the volume of their ear-splitting pre-dawn calls to prayer.
