This book highlights the true nature of an Islamic state in the light of the teachings of the Holy Qur'an and the examplary conduct, both personal and collective, of the Prophet of Islam and the Rightly-Guided Caliphs. It explains that an Islamic state is not a theocratic polity as its critics assume. Instead, it is a welfare state in its truest sense, based on justice in totality and the concept of Tawheed (Oneness of God). The book also examines why an Islamic state could not be established anywhere in the world after a short period of the true caliphate.// Born in 1942 in Azamgarh (UP, India), he is a retired professor of Hamdard University, New Delhi.
