The earliest Quranic manuscripts date back to the 7th century, with the text written in a simple, cursive script known as Hijazi script. As Islamic art and calligraphy evolved, so did the scripts used to write the Quran. The development of Arabic fonts was influenced by various calligraphic styles, including Kufic, Naskh, and Thuluth. These scripts were meticulously crafted by skilled calligraphers, who considered the Quranic text a sacred art form.
