Sounds like they are decent British Muslims
Apologies if I’m reading something into that that wasn’t intended, but I find that comment a little odd, and in fact slightly off.
I’d very much go with what @theotherjonv said, that the idea of Muslims doing something like this being “remarkable” is a bit depressing and, perhaps unconsciously, seems to acknowledge the attempt by some sections of the the popular (and social) media to portray Muslims as all about bombs, beheadings, forced marriage and child rape.
In my experience, there are really quite a lot of “decent” Muslims, and some of you might be shocked that they are not even all of the “British” variety. There are a lot of practical, hands on, hard work, unsung and un publicised good things being done across communities by those who follow Islam every day, and a lot more than is being given back to society by a lot of the self-identifying “Christians” who spout divisive, reactionary bigotry about them.
