Recitation of the Koran
I am not sure of the particulars, but this must be a relatively recent phenomenom.
Until very recently, over 99% of the Arabs in Chile were Christian. Only 1 out 4,000 people in Chile were Muslim – most of those being new arrivals.
The poster’s name, Roberto Leiva, does not come across as a Muslim name or even Arab.
So I am not sure of the particulars here.
