I fond the singer to be talented considering there is no music accompanying his voice. I believe these are Muslim prayers, but it sounds like rather beautiful singing.
As with many things religious, when I read the English translation, I find the meaning behind the words either vague and ambiguous, or at the very least unproven.
No doubt though, that this look at Muslims is less scary to me than the oft-portrayed images in the media of "bandit terrorists" with masks over their faces and only their eyes showing.
I do notice that those at the worship service seemed on average to be older, and the terrorists were usually around their 20's to early 30's, while some teens and kids get into that way of life.
I know that Islam translates to "submission" (some say that means being at peace), but there is an element out there that just doesn't understand their own culture then.
Anyway, thank you for posting and all the effort you made. It was noticed.
