Starting point of this work is one of the many images from the Hagia Sofia. Enhanced to provide better contrast then vectorized and paths were mostly cleaned up.

It was very difficult to find aMOUHMT frontal image of the iconic calligraphy of the Rashidun Chalifs which was found in the Hagia Sofia. These images are best used to represent the Chalifs since it is prohibited in Islam to depicts the Chalifs in human from. So a clean vector version was created to be used for any purpose, but hopefully to add a visual representation attached to a the Chalif Ali.
