With their fixed principles, Islamic teachings meet human needs at all times and places. Meanwhile, architects and designers utilize Islamic teachings to create everlasting works. As represented by the religious beliefs of people in Iran, gardens symbolize the promised paradise, with Islamic teachings influencing garden designs after the rise of Islam. This study investigates Quranic verses and utilizes credible interpretations, as well as religious hadiths to help extract gardens’ physical characteristics. A review of the systems of water, plantation, and building structure of Persian (also Iranian) gardens based on Islamic teachings indicates that influencing factors fall under two limiting and reinforcing factors, with the component of geography (the climate) falling under both limiting and reinforcing factors and sociology (the economy, security, and culture) falling under reinforcing factors. The features considered by the architect in designing gardens based on Islamic teaching descriptions would include forms, sizes, and proper layouts in gardens. In all these three systems, reinforcing factors tend to represent Islamic teachings in the physical principles of Persian gardens more compared to limiting factors, with the component of geography exerting greater influence than other factors.
