fraternity groups

Question about Fraternities (Or similiar groups)?

I know Christianity has groups like the Knights of Columbus, freemasonry, etc… Does Islam have any International Organizations like that but are in service to the exalted Allah, praise be to he.

Salam if you are muslim otherwise Alikum

Following are some helpful website about Islamic Organizations
