No not really, I've seen Alah's name several times in pomegranites, I've also seen Hindu statues drink milk, I've seen the image of Jesus on the side of a railway wagon, a Buddhist temple survived the 'A' bomb so similarly the mosques survived because they will be the best and most robustly built buildings in the area.
If you believe in God you will see him working all around you this perhaps is an example of this but as I've pointed out above it does'nt specifically signify the existence in a specific deity.
Well not to me anyway.
