Islamic calligraphy is the artistic practice of handwriting and calligraphy, based upon the alphabet in the lands sharing a common Islamic cultural heritage. It includes Arabic Calligraphy, Ottoman, and Persian calligraphy. It is known in Arabic as khatt Islami (خط اسلامي), meaning Islamic line, design, or construction.
The development of Islamic calligraphy is strongly tied to the Qur’an; chapters and excerpts from the Qur’an are a common and almost universal text upon which Islamic calligraphy is based. Deep religious association with the Qur’an, as well as suspicion of figurative art as idolatrous, has led calligraphy to become one of the major forms of artistic expression in Islamic cultures.
