What Wikipedia says about Arabic Calligraphy
This art form is based on the Arabic script, which for a long time was used by all Muslims in their respective languages. They used it to represent God because they denied representing God with images. Calligraphy is especially revered among Islamic arts since it was the primary means for the preservation of the Qur’an. Suspicion of figurative art as idolatrous led to calligraphy and abstract depictions becoming a major form of artistic expression in Islamic cultures, especially in religious contexts. The work of calligraphers was collected and appreciated.
