Arabic calligraphy is an Islamic art form that is primarily used for religious expression and creativity, as it is seen as a way to teach and spread the teachings of the Quran using beautiful penmanship. The art of calligraphy flourished in the Islamic world because verses from the Quran emphasize the importance of learning through writing using a pen. Most Arabic calligraphy incorporates verses from the Quran and words of the Prophet Muhammad to clarify the religious purpose of the structures they adorn.
