Universal mosques are built today by countries for political and showy reasons and in order to appear as countries that respect Islam and care for its affairs. They are built isolated in a vacuum, with enormous areas and costs, on hills and in large open spaces, as a symbol and icon of the state they represent...and in this way they resemble huge Gothic cathedrals, which were often built for purely showy reasons. This is a negative and dangerous change in the reasons for building such buildings It was built in the heart of the city, and in Islamic culture the city was called a city because it contained a mosque. Then the entire city is built on this great mosque, and all the main roads go from it and to it, and public buildings, shops, and markets surround it. Thus, it constitutes a religious, social, and economic magnet capable of attracting people and securing the center with a movement that is repeated five times a day. Changing the nature of the use of these dangerous buildings deprives the contemporary city of its vibrant, active and dynamic heart... thus leading to the weakening and marginalization of its centre.
