Iranian Islamic gardens like almost every cultures, represent beauty and happiness and improve the public perception. It has also special geometry with philosophical concept related to Islam’s doctrine that is the focus of this research. Following Quran’s contents, paradise is a beautiful sophisticated garden that something flows under its trees. So the comparison between the somatic geometry of Iranian Islamic gardens and the sophisticated conceptual heavenly descriptions of paradise in Quran is the matter of this research. Thus the configurations of the geometry, based on the paths of rivulets and airflow patterns in the gardens are considered here. The research method is interdisciplinary: in the first step, after initial considerations and exploring, the principals of Iranian Islamic garden’s geometry were extracted by a comparative - descriptive method in some selected case studies. The construction of paradise in Quran frames the trajectory of analysis so the next step is analyzing the paths and geometries with a consequential analytical method. Some simulations of the inner wind are presented also. The simulations include a validated computational fluid dynamics (CFD) model to illustrate the airflow current in this geometry. The results demonstrate the physical imagination of Quran’s perception of paradise in Iranian Islamic gardens and the flows under the trees that is framed in a heavenly geometry.
