The architecture of the contemporary Islamic mosque has witnessed a clear impact on technological revolutions in general and the nano revolution in particular. Technology in the twenty-first century dominated various areas of life, especially architecture. The use of nanotechnology allowed the production of new materials and improved properties of other materials. Which opened up the architects a prospects for the formation of an architectural product characterized by free formation and interacting with the natural environment and less energy consumption through the employment and use of improved building materials and supported by nanotechnology such as glass, concrete and other materials, From here emerged the problem of research represented by (the existence of cognitive ambiguity about the impact of nanomaterials in Arab Islamic architecture in general and the architecture of the Islamic Mosque in particular), As for the aim of the research, it crystallized in exploring and learning about the impact of nanomaterials in the architecture of the contemporary Islamic mosque. For the purpose of achieving its goal, the research followed an approach based on analysis, synthesis, and description for a set of previous studies. In order to build a comprehensive theoretical framework for the impact of nanomaterials in the architecture of the contemporary Islamic mosque, the research assumes that (the impact of nanomaterial technology on the functional performance of buildings is greater than their effect on building formation and environmental performance.). The research found that the impact of nanomaterial technology on the architecture of the contemporary Islamic mosque is crystallized by achieving the imagination of the designer in finding and creating complex and non-standard forms based on simple forms related to the identity of Arab Islamic architecture through its contribution to developing computers and increasing their speed and efficiency, which opened up to Designers create new horizons and enable them to find new and strange shapes characterized by complexity, flexibility, streamline and immateriality. Nanomaterials influence the architectural function in the contemporary Islamic mosque by fulfilling human values and the ethical dimensions of architecture (identity, privacy, independence, communication, etc.), And fulfill the functional requirements of the mosque, such as increasing the capacity of spaces in order to accommodate the largest number of worshipers and reduce the number of columns and physical and visual obstacles that impede the principle of contacting the rows of worshipers and not cutting them, as well as the desirability of the worshipers ’vision of the sermon, As well as providing an internal environment suitable for worshipers such as providing adequate lighting, natural ventilation and appropriate temperature, Nanomaterials affect the properties of the shape in the contemporary Islamic mosque by achieving the characteristics of lightness, flowery, immaterial, continuous change, brightness, flexibility, showing the interior, the transmission of visual effects between the interior and exterior, the use of three- dimensional decorative configurations, employing shadow, light, and harmony in building materials and cladding
