The architecture-planning solution of the mosque in the village of Rustov is little different from the "Ardebil" mosque in Guba. Comparing the mosques leads to the idea that they were built by the same masters. The only difference is that the Rustov mosque is slightly bigger than the "Ardebil" mosque. Its prayer hall is divided into four parts by three rows of columns (three columns in each row), while the prayer hall of "Ardabil" mosque is divided into three parts by two rows of columns (two columns in each row).
