Muslim architecture:Practice of Islam by Muslims (as individuals and communities) reflecting the difference of types and styles over geography and history.

Physical heritage in the Islamic world such as famous mosques, courtyard houses and various architectural styles are Muslim architecture. They have come out as an interaction between the Islamic principles, the place and the people who adopted Islam as a religion and way of life. But they don't necessarily reflect Islam.
