"I've seen stained glass work in many architectural buildings, but this is exceptional. From dawn, the mosque is filled with color and light, dappling the Persian rugs, the ceiling and wall tiles with patterns and colors.

"I visited on a winter morning and waited for the light that moves gently from left to right to fall exactly in the center so my photo could be completely symmetrical."
