We get sporadic questions from Islamic users that have very specific investing restrictions, because of their faith.
Those are good questions, and I welcome them into the site. I think a tag for these questions would be a good thing, to bind them together.
Maybe islamic-investment or islamic-banking, something in between.
Possible candidate questions for this tag (not exhaustive):
A country tag may not be recommended in this case, because Islam is present in almost all countries.
At least for investing, the word "Sharia" would be most appropriate - Sharia being the name for the set of laws in Islam that apply. This is very consistently used in my experience with regard to investments; banking it doesn't seem to be as regular, but it is still the proper term ("Shariah compliant finance").
I also think that, while for non-Islamic folks "Islam" would be the word we expect, for those who follow that faith "Sharia" (or "Shariah") would be more commonly understood.
As such, I'd suggest:
with predefined synonyms
shariah-compliant-financing sharia-banking shariah-banking islamic-banking islamic-finance islamic-investment
all of which seem likely to come up to me (and if we have enough that do, the autocomplete will do the rest for us).
I think this is a good idea, and I'd suggest islamic-finance, though either of the two suggestions in the question are fine too.
The list of question is small. If we still want to have a tag; islamic-banking is a better tag as it is well known word. It would be easier to think the term and tag.
