In Saudi Arabia, voting rights are limited to Muslims.
Explanation:
The state of "Saudi Arabia" is an "Islamic theocracy". If a non-muslim individual wishes to have the citizenship of Saudi Arabia, it is mandatory for him to convert to Islam.
Though there is a certain percentage of non-muslim population in the country, the government of Saudi Arabia does not recognize them as official citizens of the country.
Thus, voting rights in "Saudi Arabia" are only limited to Muslims.
