Human relations are so integrated that no state can have complete freedom of action under its principles unless the same principles are not in force … - Syed Abul Ala Maududi

Finally, no less a figure than Sayyid Abu ’l-‘Alā’ Mawdūdī, one of the major thinkers behind modern Islamist ideology, said that in an Islamic state as envisioned by him, “no one can regard any field of his affairs as personal and private. Considered from this aspect, the Islamic state bears a kind of resemblance to the Fascist and Communist states.”

[Unbelievers] “have, however, absolutely no right to seize the reins of power in any part of God’s earth nor to direct the collective affairs of human beings according to their own misconceived doctrines. For if they are given such an opportunity, corruption and mischief will ensue. In such a situation the believers would be under an obligation to do their utmost to dislodge them from political power and to make them live in subservience to the Islamic way of life.”

(The) materials for the constitution of an Islamic state are to be found in four principle sources, the Koran, the Sunna of the Prophet, the conventions and practices of the Four Rightly Guided Caliphs, and in the rulings of the great jurists of the Islamic tradition.
