Originator of the heavens and the earth" بدیع السموات والارض  ( Al Baqarah – 117 )
Everything We created is precisely measured. " إنا کل شئ خلقناه بقدر " ( Al Qamar – 49 )
If anyone meditates in the verses of the universe and creation he must see the creativity of God in all Gods creations, as we can find that everything is completely arranged and consistency  and all the universe is ruled by certain laws, as God created everything by measure and this is the secret of creativity in this great universe.
Scientists researched and studied the geometrical sequences arranging the universe which is the sacred geometry which arranges and controls all the forms of existence and life starting from eye cornea, DNA molecules for humans, flowers petals, diamond crystals, tree branches and animals down to galaxies, solar systems and even the chemical composition of air is arranged in a certain law. The science of sacred geometry depends on deep understanding for these universal aspects and geometrical arrangements which consists it including geometrical forms and mathematical ratios which is used for the design of everything in nature, because of this all old civilizations used it in religious architecture with a special form aiming the creation of spiritual energy field connecting man to universe by using the same ratios of building style, and from here comes the research problem which can be determined in the following question: What are the sacred geometry aspects in the arts of Islamic architecture and decoration which acquires it its creative artistic aesthetics? Through the studying of sacred geometry concept, the forms, and mathematical geometrical arrangements used by scientists based on aesthetic proportions in nature and applying this in arts of Islamic architecture and decoration through studying samples of arts of Islamic architecture and decoration. The research aims to prove that Islamic architecture and decorations didn’t come accidentally but it is based on geometrical and mathematical concepts depending on sacred geometry which arranges universal construction. The results of the research refers to the conclusion that Islamic architecture and decoration are all based on the golden ratio of mathematical and geometrical basis which gives it atheists which is clear in the visual sense of comfort through its connection to universal sacred geometry which makes it harmonious with the surrounding universe.
