The truly unique Muslim architectural style was gradually established after the 8th century. Just like when we see a person wearing a white robe and a headscarf, we will say that he is an Arab. As soon as we enter the Islamic mosque, we will find its architectural style. Germain Bazin pointed out that all the structures designed by architects have a facing full of practical decoration. Structural components themselves soon became the theme of decoration, such as corner arches, which were used to transform the square into a dome. This feature is split and propagated, and it is deformed into a stalactite shape. This stalactite is grafted on arches, domes, stigmas, zenith, streamers and lintels. They are all decorated with flowers and leaves, made of plaster, plaster, wood and mosaics, or carved with Indian marble. In Persia, influenced by Safi dynasty, it was made of painted pottery bricks, just like a robe wrapped around the whole building. From this we can say that the architectural style of Islam is distinctive and unique.
