The Islamic Centers are generally involved in performing the Friday congregational prayers known as Salaat-al-Jummah, distributing literature, charitable activities, online propagation and donating informative materials on Islam to various religious and cultural institutions throughout the country. For example, the Fátimah Az-Zahra Islamic Center provides introductory classes on Islamic doctrine and history. These classes, which are open to the general public, are not solely religious in nature: courses in foreign languages and efforts to improve adult literacy are also offered.[4]
