- I think we're all happy about changing the icon Change the Islam.SE favicon (currently "Is") to something Islamic?
- But I don't think we're going to reach a consensus anytime soon unless things change: Islam.SE temporary logo — can we vote?
My impression is that we might be able to get everyone on board with "Islam" in Arabic, i.e., اسلام, as an icon... provided we can reasonably squeeze it in the smallest icon.
Rafid suggested using Islam اسلام in Kufic script. So I attempted it myself: 
(main) 
(meta).
Question: Would you be happy with this hand-drawn Kufic-style "Islam" اسلام as a favicon?
I couldn't find something online, so I drew it myself. This is my first attempt at a Kufic drawing, so please let me know if it needs fixing (it's probably not perfect). Or, better yet, please open up e.g. paintbrush and do so, and post an improvement as an answer.
In any case---it's only a temporary icon.
The 16x16 icon is hardest to draw. I expect it'd be comparatively straightforward to do the other-sized icons. I might do so if there's a chance we can make it work.
Actually, it was very little effort to make corresponding 32x32 icons; just make the lines twice as thick:
The current icon is 
, and some alternatives (drawn by me) are 
and 
(abbreviation "اس" just for this smallest icon).
There seems to be some flexibility:

(a simple image)CiviCRM's logo:
(a simple image)CraftCMS's logo:
(red)HSM's logo:
(rectangular)Chinese's logo:
We got it changed a few days ago because we managed to agree.
