Read the passage and answer the question:

The developments that followed the coming of Islam were not confined to ruling elites; in fact, they permeated far and wide, through the subcontinent, amongst different social strata – peasants, artisans, warriors, and merchants, to name a few. All those who adopted Islam accepted, in principle, the five “pillars” of Islam. However, the universal features were often overlaid with diversities in practice derived from sectarian affiliations (Sunni, Shi‘a), and the influence of local customary practices of converts from different social milieus. The complex blend of a universal faith with local traditions is perhaps best exemplified in the architecture of mosques. Some architectural features of mosques are universal. However, there are several features that show variations.
