How Islamic Architecture is different from Muslim Architecture?
Asif, Tricky question. Maybe one could say that "Islamic Architecture" refers to public and official architecture made in the name of Islam and that "Muslim Architecture" refers to the private and usually vernacular (home grown) architecture made for people who are muslims.

Maria, "Gold-leaf" (paper-thin gold) may have been used to illuminate the calligraphy around the walls.
