A complementary theme is the relation between Mashrabiya and light. Ghiasvand et al. (2008) explain how in Muslim culture light is a “symbol of divine unity”; Aljowder (2014) supports this view through her research on the relationship between light and visual privacy.

Both scholars agree that the Mashrabiya enables the passage of divine light which modifies other elements and forms patterns. Ghasvand (2008) suggests that with the right light coming through the pierced screen, the facade resembles lace. Light and shadow also add dynamic rhythms to architecture and its forms, giving texture to smooth surfaces. However, summer light can be harsh and cause severe temperature increases in the interior. As Samuels (2011) and Aljowder (2014) note, Mashrabiya screens fulfil this cultural need by responding to and blocking direct light and reducing solar gain.
