In this work, the construction line technique has been used and the text of the work is Asma Allah.
The calligraphic or rational calligraphy is one of the types of Islamic calligraphy which is a kind of angular Kufic calligraphy and is obtained by drawing geometric shapes such as squares, rhombuses, rectangles and parallel and intersecting lines. The building line is an unadorned and geometric type of Kufic line that is designed based on checkered houses.
The basis of Kufi is the construction of horizontal and vertical extensions and the rotation of the line with a uniform thickness in the horizontal or vertical direction so that all the geometric surfaces of the shape are filled with these horizontal and vertical writings. In some types of building kufi we come across examples where both black and white are composed of words that both have a meaning called difficult or overlapping kufi.
