Islamic art cannot be defined as a particular kind of art as it covers many different forms of art. Going back to more than 1400 years it varies from different Islamic cultures, lands, and people. Islamic art covers from architecture calligraphy, paintings, glass, pottery, carpets and embroidery.
The emphasis in Islamic art is on ornamentation, rather than art. Calligraphy inscriptions are the most popular style of Islamic art, especially the calligraphy and decoration of the Quran manuscript. Over the centuries Islamic art developed from many different eras and took influences and styles from such as Persia, China, and Asia.
For Muslims, Allah is the focus of their lives and at the centre of their hearts for worship and aspiration. So Islamic art does not focus on physical qualities rather the spiritual representation of objects and beings. Beauty is quality and always will be a quality of the Divine. For Muslims Allah is beautiful and loves beauty. As Islam is a way of life for a Muslim and makes the life beautiful, and so Islamic art should be used and created to make everyday things beautiful.
Islamic art also uses a lot of repeated pattern such as geometrical and floral designs. The repeated geometric patterns are also seen as spiritual, in the sense that the patterns reflect the language of the universe and make the believer reflect on life and the greatness of the creation.
