Ali Abd al-Raziq's controversial 1925 work, 'Islam and the Foundations of Rule,' fundamentally challenged the widely held belief that the Islamic caliphate was a divinely ordained institution. Abd al-Raziq argued that the caliphate was a human, political construct, not a religious necessity, and that Islamic law did not prescribe a specific form of government. This groundbreaking perspective advocated for the separation of religious and political authority, paving the way for secular governance. The book ignited a fierce debate across the Islamic world and led to the author's dismissal from his religious post, marking a pivotal moment in modern Islamic political thought.
