In this book Maulana Wahiduddin Khan explains the role of Islam in history. Elaborating on the issue, he writes that in the wake of the revolution in the first phase of Islam, religious freedom took a decisive course in history, spurred on in the initial stages by Muslim action. And in later stages it was activated by the participation of non-Muslim nations. This took place in the first half of the twentieth century, firstly through the League of Nations and later through the United Nations, when all the nations of the world unanimously declared that religious freedom was a fundamental right for all and could not under any circumstances be abrogated.
