I was practicing walking in this rough surface when the imam began calling to prayer at the sunset. I did not pay attention; he was not calling for me anyway, I thought:) then I fell down so bad. Was that a quick warning for me, or just an accident, I still don't know. Next time I will be careful, just in case.

PS: some background info about Turkish/Islamic tradition about adhan (call to prayer). On hearing adhan, one enters into a respectful mood and repeats silently what the imam says. It is related that the prayers made during adhan are accepted.
