What is the content of Ali Abd al-Raziq’s book, "Islam and the Foundations of Governance," concerning the imamate, and how can one respond to those who say that there is no evidence for the issue of the imamate in the Quran or Sunnah?

The book "Islam and the Foundations of Governance" by Ali Abdel Raziq calls for the separation of Islam from governance, claiming that it is solely a religion. The Azhar Council of Senior Scholars condemned the book and its author, expelling him from the ranks of scholars.

If the intention behind the Imamate is to unite Muslims under one Caliph and one banner, then this is the truth and a duty, because the disunity of the Ummah has made enemies covetous of it.

Secularists do not base their arguments on the Quran and Sunnah; rather, they confine Islam to mosques and deny its connection to governance.
