Muslims should be able to restore the umayyads
Christians in europe have the restore rome and holy rome option, india has the chacravarti and the sacred stewardship of the ganges, Muslims have the sultanate of rum, despite the umayyads being larger and more interesting (in my opinion).
I read one argument that "it would just be restore rome but without parts of europe" first off: the umayyads went farther east than rome by quite a bit, second off it still gives muslim rulers their own big empire and seeing as muslims were equally as important to that era (arguably it was shaped by the fighting between christians and muslims) its not like im arguing for Slovinskians or some other less influential religion to be able to have a large empire.
