The scribe, for instance, was required to be in a state of ritual purity (ṭahārah), wear clean clothes and face the Kaʿba (in Mecca) while engaged in copying the Book (al- Kitāb). The copying of the Qurʾan was very meritorious for the Muslim. In fact, it was regarded as an act of worship, which drew upon the calligrapher numerous blessings from God.

Some of the most visually stunning manuscripts of the Qurʾan were produced in the early Abbasid period (8th -10th centuries). They exhibit a variety of calligraphic styles and decorations, as well as diacritical pointing by means of slanted strokes and vocalization using red dots. The horizontal-format manuscripts.
