In the eyes of history, religious toleration is the highest evidence of culture in a people. It was not until the Western nations broke away from their religious law that they became more tolerant, and it was only when the Muslims fell away from their religious law that they declined in tolerance and other evidences of the highest culture.

The tolerance within the body of Islam was, and is, something without parallel in history; class and race and color ceasing altogether to be barriers.
