Arabic calligraphy is the artistic practice of handwriting and calligraphy based on the Arabic alphabet. It is known in Arabic as khatt (Arabic: خط), derived from the word 'line', 'design', or 'construction'. Kufic is the oldest form of the Arabic script.
From an artistic point of view, Arabic calligraphy has been known and appreciated for its diversity and great potential for development. In fact, it has been linked in the Arabic culture to various fields such as religion, art, architecture, education and craftsmanship, which in return have played an important role in its advancement.
Although most Islamic calligraphy is in Arabic and most Arabic calligraphy is Islamic, the two are not identical. Coptic or other Christian manuscripts in Arabic, for example, have made use of calligraphy. Likewise, there is Islamic calligraphy in Persian or the historic Ottoman language.
The Arabic alphabet is known to be used by one of the most widely used language scripts in the world. Many scholars believe that the alphabet was created around the 4th century CE. The alphabet consists of 28 letters written from right to left. Each letter can be written in four ways, depending on where the letter is placed in a sentence. These four locations are also known as initial, medial, final and isolated.
The pens used for Arabic calligraphy vary from Latin calligraphy. The tools used for calligraphy are different assortments of pens and calligraphy ink. The most common calligraphy pen used is Qalam.
The Khamish pen also known as a reed pen is used by Arab, Turkish, and Iranian calligraphers. The reed of the pen is grown along rivers. Although this pen has been used for over 500 years, preparing the pen is a lengthy process.
The Java pen is known for the tool's hardness and ability to create sharp edges. The pen is good to use for small scripts.
The Handam pen consists of the same strength that the Java pen has. The pen is good to use for all kinds of scripts.
The Celi pen is used for large writing in Arabic calligraphy. These pens are made from hardwood and cut and drilled.
The two most popular scripts used for Arabic calligraphy are Kufic and Naskh. Kūfic was derived from Iraq and initially used for inscription on stone and metal. Naskhī originated from Mecca and Medina. The script is used as a cursive script, for example on papyrus and paper.
The Thuluth script used during the medieval times is known as one of the oldest scripts to exist. The script was used on mosques and for Quranic text due to the appearance of the text.
The Nasta'liq script is used more for Persian than Arabic scripting. Because of the upward slant to the left, the script is seen as different from the other scripts. The cursive look creates an elegant look when creating.
The Diwani Script was created during the Ottoman era. The lining and lettering of this script creates a sense of closeness when writing. Due to this reason, it's difficult to read since the letters intertwine.

The shift from Arabic calligraphy to Arabic typography presents technical challenges, as Arabic is essentially a cursive script with contextual shapes.
Taking Shape: Abstraction From the Arab World, 1950s-1980s, a 2020 installation at New York University's Grey Art Gallery, explored how Arabic calligraphy, with its ancient presence in visual art, influenced abstract art in the Arab world. For Madiha Omar, the Arabic alphabet was a means of expressing a secular identity and appropriating Western painting, while Omar El-Nagdi explored the inherent divinity of Arabic calligraphy.
