Abstract
In this paper, we tried to interrogate measurements and numbers and extrapolated them, through an analytical study,and four relationships that are found that are called the basic equations for the design of the Malqaf, containing four basic units and their repetition, each of which was expressed by a bundle of identical straight lines that represent the equations of a straight line passing through the principle of coordinates, These four identical line bundles relate the size of the room, the size of the Malqaf, its width, depth and height from the roof of the building, and the errors were calculated, so these errors were among the permissible human measurement errors. These relations werea mathematical proof of the straight monotheistic thought on which the Islamic religion is based and on the idea of unity and repetition in Islamic architecture in an innovative mathematical way.
