It is permissible to grant a non-Muslim the nationality of a Muslim country provided that the danger of Fitnah (sedition) is secured and that his good intentions are sensed. However, he is not allowed to reside in
Arabia unless he embraces Islam. This is based on the Prophet's command to expel the non-Muslims from
the Arabian Peninsula
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
