Riba and its forms in early Islamic society

Riba (interest) is intrinsic to capitalism. Riba and Capitalism exploit labor and divide society into 'haves' and 'have-nots.' Therefore, riba is a sin and equated to waging war against Allah and the Prophet in al-Qur'an. Riba must be eliminated as part of a country's Islamization. Not only bank interest, but all forms of interest-bearing transactions must be eliminated including share cropping, black market dealing in foreign currencies, and renting houses.
