Though the country has the major portion of the residents following Islam, there are no constraints for those who belong to the other religious groups. The majority of the people, who practice Islam in Djibouti, are Sunni Muslims. The considerable foreign group of people of Djibouti sustained Roman Catholic, Greek Orthodox, and Protestant and Ethiopian Orthodox churches.
The constitution of Djibouti, after declaring the religion of Islam, the state religion, also provided freedom of religion. The national holidays of the country include the Muslim holidays on the Birth of Prophet Muhammad, Eid-al-Fitr, the Islamic New Year, Eid al-Adha and also the Ascension of the Prophet. For the non-Muslims of the country, proselytizing is discouraged.
The Arab merchants had brought in the religion of Islam along with trade in the interior part of the country. Both the Afar and the Issa are Sunni Muslims and both of the groups follow the law of the Shafiite School. Each of the towns of Djibouti has a mosque.
